"Failed" Xserve disk running well in USB enclosure

Hi everyone,
I'm curious if anyone else has tried this and what their results might have been.
I had a pair of "bad" Xserve RAID hard drives (250 GB Hitachi's manufactured in April 2004) laying around from the last year or two. I don't remember the exact error messages that they threw at the time of failure, but I swapped them out and the RAID rebuilt itself on the new disks without issue.
I was cleaning some junk out the other day and happened upon these disks. I decided to pop one out of its chassis and drop it into a Rockfish USB 2.0 enclosure to see what might happen. When I powered it up and connected it to my Intel MacPro (10.4.11), I was asked if I would like to initialize the disk. Did that, and to my surprise, the disk showed up on the Desktop without a problem.
At this point, I decided to "push" the disk to see if I could get it to fail. Did the following:
1) Ran a complete block scan with Drive Genuis. All ~490 million blocks passed and not a single bad one found.
2) Formatted the drive to MS-DOS with Disk Utility and did a block scan in XP. Got the same result as #1 above.
3) Successfully cloned my MacPro system using SuperDuper to the drive twice. Booted into the clones and ran them for most of the day without problem before cloning the USB back to the internal drive (again, without problem).
After doing this, I was curious on the status of the second disk. After swapping it into the USB enclosure, I found that it too seems to be "OK".
In case you are wondering, I also tried reintroducing one of the disks from the above into the RAID and it wouldn't accept the disk. My guesses are 1) the RAID is less forgiving to drive problems then having it in the Desktop setting; 2) the fact that S.M.A.R.T. is not supported via USB 2.0 is letting me get away with doing this since errors are not being reported; 3) the RAID drive chassis is the source of the problem. I would think that #3 in less likely then #2 and #1 since the chassis seems to be just drive and power cables.
Has anyone else tried something similar with "bad" Xserve RAID disks? If so, what were the results? At this point, I'm planning on using these disk as noncritical storage devices since they seem fairly solid. To bad they can't be put into the SATA bays of the MacPro....
Looking forward to input.
Cheers,
Scott

Here is an update:
The "failed" Xserve drive has been performing well over the last week. As Tony mentioned in a previous post, his attempt to freshly install OS X onto such a disk sometimes failed or during booting. To test this, I installed Leopard client to the disk successfully and was able to boot my desktop with it. However, after installing the 10.5.1 update, I could not longer boot from the disk. It would start the boot process, but would get stuck on the grey screen and not proceed any further (I tried it a few times, all cases ended just as Tony described). In fact, the boot disk seemed to stop spinning at that point and I was forced to shutdown using the power button.
Thinking that I may have finally "killed" the disk, I ran Disk Utility on it. To my surprise, it found no errors. So I erased the disk, cloned my Tiger 10.4.11 system and was able to successfully boot into it without problems.
SO.....
Booting from a cloned OS X system WORKS, but booting from a fresh OS X install DOESN'T?!?!?
Hard for me to explain why this might be the case. Any opinions from people reading this?
Thanks.

Disk manager not assigning usb enclosure drive a letter

LAPTOP: Toshiba Satellite 1135-S155 Windows XP Home Edition.
current preinstalled 40 GB HDD message says it is failing & backup. want to backup to usb enclosure using western digital 80 GB HBB (didn't want to shock the system). computer does detect my toshiba 4 GB flash drive & assigns drive letter E. DEVICE MANAGER detects the western digital hdd as: usb device generic void disc, PROPERTIES claims Location 0; VOLUME shows Disk 1, unknown, unreadable, partion style as Not Applicable, 0 MB. Disk Management does not show usb device thus doesn't even assign a Drive letter to it. not attaching any other usb device while i have usb enclosure hdd hookup. have gone through troubleshooting, reinstall, basically what i can find to do from "Windows XP Inside Out Manual" unless not looking in right place.
Should i place new western digital 80 GB HDD into computer, use original restore discs that came with system, then place old 40 GB HDD into usb enclsoure and copy that hard drive onto the new 80 GB HDD? Or what?
found a hero once in this forum & hopefully will find you again. love my old clunker & don't want to give her up yet!

Hey, I'm back. And with SUCCESS!!!!
Was able to take new hard drive and connect to a laptop running VISTA. VISTA recognized the new hard drive that was in the same USB external enclosure that I was using. VISTA recognized in both Device Manager & the much needed DISK MANAGER. Was able to initialize immediately w/no problemos!! YIPEE SKIPPY.
Did I dare to be BAD? You betcha! Took the initialized HD back home & hooked up to the TOSHIBA Satellite 1135-S155. Again, success. My old DISK MANAGER saw it, I was able to continue to partition & format it!!! Why WinXP Home Edition couldn't initialize it? - Is one I'll leave for the cosmos.
Anyway - Who says you can teach an old dog new tricks - HA! Little did they know about ME - oh, ahem, and of course JERRY aka The HERO and also The Wondrous CEE-64.
So excited was I, and how could I NOT be? That I immediately tried the FREE Acronis True Image Western Digital Edition that was suggested by The Wondrous CEE-64 on the 08-29-2009 7:03 PM session. As I was hoochie-cooching around in my NEWER SHOES, I suddenly I noticed that after burning 'Volume 5' onto a CD-R - ERROR MESSAGE (Error occurred while writing to file), hmmm - inserted a different CD-R, again same message, hmmm - inserted a different CD-R yet, hmmm - same message & got the hint. Shall I go on? OK you asked for it.
After checking Western Digital website & running one of their programs. The initialized, partitioned, formatted WD Scorprio Blue HD was just being recognized as a USB Generic Mass Storage Device. Hmmm - maybe because the Western Digital Edition couldn't detect the new hd being from WD, could that be the problem? Closed and uninstalled the FREE Acronis True Image Western Digital Edition.
Per HERO Jerry's suggestion on 8-27-2009 12:00 PM, I downloaded FREE Acronis True Image 2010 Home Edition. Loaded fine, reread the users guide (serveral times). Attached the USB external enclosure (YES, the hard drive was inside) started the program, used CLONE DISK option, TA-DA it worked.
Yep, it has to reboot. Okey-dokey. UNTIL it came to me having a problem. This TOSHIBA requires an F1 button to be pushed after start up AND it doesn't like the USB GENERIC MASS STORAGE DEVICE to be attached during boot up. It stops & requests either F2 (setup) or F_ (I forget) and doesn't respond until I 'safely remove the USB device', then the F1 button. SOMEHOW, after swapping out the drives (THAT went really well, pat on the back) & Started the computer up. YUP, Toshiba intro screen pops up, then the F2 etc. screen, & waited longer than usual. Pushed the F2, saw that it is the WD drive with larger capacity, exit, then a dark screen with a flashing cursor in the upper left hand corner came on. That was it. Nothing for a minute or two, tried just shutting the laptop off. Wouldn't. Ended up swapping the hard drives while the fan was running. Using the old TOSHIBA 40GB drive again.
Whada say? One more time for old times sake? Or should I just hang it up? What do I do now, pleazzzze and thank-you.
PS - Can't wait, this stuff is getting good!

SATA Problem: Can see hard disks in USB enclosures, but not internal

I have a mid-2010 macbook pro 13". The other day, it crashed on wake-up, and would not boot. I had a OCZ Vertex SSD boot drive, and the OEM hard drive in an optibay enclosure (replaces the optical drive and used only for data). I used this setup for one year with no problems. After much troubleshooting, I found that I could see the SSD drive by booting into a recovery partition that I have on a USB stick, and putting the SSD in a USB enclosure. Then disk utility could see it, but not mount it. The label on the boot partition was "lion", but it changed to "disk1s2". I was able to repair the drive using disk utility, and then boot from it using the USB enclosure.
Once booted, I could still see the OEM hard drive with no problems. So I powered down and put the SSD back inside the case and rebooted. It booted in safe mode, but it booted fine. The next time I rebooted, it would not boot. I swapped the OEM drive and the SSD drive, and then the sytem booted with no problems and I was able to use both drives.
One day later, I noticed my OEM drive was no longer mounted in OSX. I took it out, put it in a USB enclosure, and OSX could see it fine. There were no errors on the disk. I put it back in the macbook and reboot but OSX couldn't see it.
So, the primary SATA port seems to be working intermittently. Three times now, a drive has stopped working on this port. Each time, I could use the drive in an external enclosure (or using the other SATA port normally used for the optical drive. Does anyone have any ideas? Could it just be the cable? It is the motherboard?
I'm trying to make this computer last at least another month or so because I need to upgrade to a larger model, and am holding out for the 2012 release.

Could be something as simple as the cable...they have been known to go bad. Got an Apple store nearby? If so, it's a cheap/easy replacement.

Compatible USB enclosure for hard disk from a 15-inch Aluminum Powerbook

My old Powerbook finally bit the dust, so I dismantled it and removed the hard disk. I want to get an enclosure to use it as a USB drive, but do not know what size or type of enclosure to purchase.
I tried to guess, and ended up buying:
Connectland CL-ENC25005 2.5-Inch Light Weight USB 2.0 Interface SATA HDD External Enclosure
http://www.amazon.com/gp/product/B0028Y4D9U/ref=oxya_ohproduct
When I got it, the connector in the enclosure was too small for the number of pins on the hard drive. Can somebody recommend an appropriate USB enclosure to use with an old Powerbook hard disk?

Hi, jakshale, and welcome to Apple Discussions. Your Serial ATA (SATA) enclosure isn't what you need, as you've guessed; your drive is a Parallel ATA (PATA, also called IDE) unit and needs an enclosure designed for that interface. Any enclosure intended for 2.5" ATA/IDE/PATA notebook drives will work. Here's one that's almost as dirt cheap as the one you bought:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817106093
Note that if you intend to use the newly-repackaged drive with a Powerbook, a USB-only enclosure isn't a good choice unless you get one that can use its own AC adapter. This is because most Powerbooks don't supply enough power through their USB ports to power an external drive. The same Powerbooks do supply sufficient power through their FireWire ports, so an enclosure that can be connected via FireWire is a better choice. If you're going to use the drive with a desktop Mac or an Intel MacBook instead of a Powerbook, a USB enclosure should be fine.

My KT3 Ultra Experience (from the nightmare to a running well system)

Well First...
I don't speak a well english, maybe because still think in spanish, so maybe find many gramatical errors.
the very very begin
The history begins with a terrible electric shock in my house, i got a Athlon XP 1700+ with a cheap PC Chips Board (810)..yeah the all in one board (video, modem, ethernet, sound) build my first system with a mixture of expectatives and dreams with my first AMD athlon XP , the system running well, before got the "great idea" to plug a Zoltrix Genie TV card for record South Park, everything is OK, so, i think that i abuse the luck, and a rainy night, i surf the net ( a XXX one... ATK... never forget that site after this) a electric shock enter trought the tv cable searching ground, someone that got this experience maybe feels a demon in a box, a white light come out from the back of the system and hit the isolated regulator ( with the sparks and all the stuff ) the light goes out and a tasty barbecue smell fill completly the room.
ohhh...
the list of cooking components:
   Athlon XP 1700+
   PC Chips 810 (a/v/r/s)
   Maxtor HDD 40GB
   Zoltrix Genie TV
   Mouse (generic)
   Keyboard (generic)
   Microsoft sidewinder gamepad
The miracle pieces:
   256MB DIMM sticks from crucial (PC 100) two of them
   External CD Burner HP CD-Writer 8230e (USB)
   Philips Monitor 17'
i learn to never watch a porno site in a rainy night... it's really bad for your system
build another system "da plan!"
in a trip to Bogotá i search in the computer mall called UNILAGO, the new system board, someone callit MOBO, my idea are this:
A Boxed Board. Candidates like ASUS , Gygabyte, MSI, with the VIA 333 chip are required.
we search in all the place, asus show its A7V333 model, but its too expensive in the price that this guy offered (maybe think that i don't search the pricewatch.com page before go to the mall... je je) in a place some guy show me a very nice box... i think the first impression counts, its the kt3 ultra board in her shiny box, next tactic ask for minimun price (...no minimun price got this board...) so i pay 360 thousand pesos for it.
wen come back to Cali ( the place i live) and after got some pesos in my bag i go to the computer mall in Cali called La passarella (remember the argentinian soccer player?) for buy the components.....
the list is this:
   Athlon XP 1800+ BOXED (got the original AMD heatsink)
   DDR RAM PC2100 256 MB
   Genius Netscroll Optic
   Genius Keyboard
   CD-Rom LG 52 X
   Case with a 300W ATX Power Supply
   Realtek Ethernet Card (Encore)
   AGP Video card with the SIS chip 315 128MB of ram
   Genius Maxfire USB (i buyit for the cheap price and anyway i don't play too much in a computer so i dont need a Nvidia Ti thing or a gamepad expensive)
wen go to the house, plug all the stuff and the process it's fine, no complicate things occur, i do two modifications first
1)to the AMD heatsink, the clip come in the other side, so i need to unplug the Power ATX supply for attach it and don't want to do the same thing every time that retire the heatsink, i disarm the heatsink and turn the clip to the other side, no problems with this mod...
2)i don't use floppy disks... I HATE IT so the place of the floppy converts in the place for the D-Bracket with all the lights and two USB... nice because i perfored the case in the right way and the usb and the lights come in the front of the case...it's a easy mod...
all the things come well so turn it ON...
KT3 Ultra first Round!
well i don' pay much attention in the first time that power on the system and hit the del key.... nothing happens and a letters of searching array and scanning devices show... after this process the amibios screen shows (the blue one, and still today don't find the option for change the color scheme like te PC Chips amibios options got) in this point i know that the rule "search the instruction booklet" it's totally necessary for many options the options that i disable and some that enable are this:
    in integrated peripherals disable the ata raid option (remember the scan devices screen?) i plug a maxtor ATA 100 hard drive to the ide cable because don't know if this hard disk works with the Raid Option maybe not because is ata 100.. so disable the option
    in power management options i activate the CPU critical temperature to 70°C
    in advanced bios settings i enable the MSI link to the future screen... nice, SMART for HDD enable. In the boot secuence put first CD-rom and later HDD
    in standard CMOS settings put the hour...(uh!), and obvious disable the nasty floppy drive (BOOT CDS REPLACE THE NEED OF FLOPPY DRIVES...)
    in PC health disable the intrussion option, because i don't have the switch for the case...
    in frecuency and voltage i find the FSB in 100Mhz but i don't change anything in this point...
after this tiny modification, i save the changes and restart....
the system boot with a CD he he... with a image of the win98 boot disk, so i formated and fdisk the drive... tooooo fast in this point.
after partition the HDD in 5 pieces and formating every partition, i reboot the computer for installing Win98...
the installation goes normal, and install all the MSI software (only for know what apps are appreciable por me) i don't have any problems, install all the drivers for every single hardware piece and the system works well... so testing es the next point.
KT3 Ultra first test after the installation
well i feel that my job are easyly...(ji ji) and all the process go OK so testing my new machine gotme like a child.
i run the test of SiS for the AGP card ( 3D thrill ) the demo of the card got a cosmic scene, comes very fast, i try to watch if someone piloting the space ship, and maybe see something
the sound are good for the include sound chip in the board, put and test all the effects and test...ok ok... nice.
microsoft direct X got some testings so i run it too ... write in run command "dxdiag" and ready for the tests, in this point i feel free to install a copy of "formula 1 2002" in the machine some guy borrowme a copy, wen i try to install got a n error.... (the first one) and the game don't install ... i reject the installation and try another game, in this point i search the Athlon XP Oem.bmp file for branding my new system... je je, and hit the window key and pause and i find that my processor runs in 1.1 Mhz... (what!!!) if this CPU is a 1800 and this speed maybe is wrong....so i read the boocklet and find in the FSB option the way for put the CPU in his real Mhz...(1.53) in this point begins the troubles...
KT3 Ultra damage my CPU??????!!!!!
Wen enter to the bios i got direct for the FSB option and put it to 133Mhz maybe this thing it's easyly too, i think, i made and save the changes... and.....
A BLACK SCREEN COMES AND I SEE THE FOUR LEDS IN RED!!!!
AHHHH!, i thinks that this processor pases to a better life after this point, with shaking hands read again the boocklet and find the interpretation for the 4 red leds signal, damage or bad installed processor.
oh, so what i do...?
i continue reading for a little FAQ in the boocklet, and nothing, only a glossary, i call a friend to helpme... ( the true geek one) the guy tell me to reset the bios with the jumper... so, i don't loose anything with this and do it...
wen the computer reboots the signals come to life... (ufff!) and the scanning device creen shows again... so i need to save again my settings.
i do all the things and save, the system turns on and windows 98 load normal again... i try to fix the FSB thing in other time i think, and continue intalling some programs.
In my CDs find a copy of formula 1 2001 no de 2002 version, because this version i installed in my other fried system i installed in mine for show and prove the 3d card...
the installation works fine and terminate ok, wen i hit the icon to play, the 3d settings window appears i select some options 800x600 32bit color and press test, a blank screen comes with some little caracters, in some point wen the test come back my system frozes and nothing happens... OHHHHHHH! what happens?.... i think, i decided to check the temperature values because in this point think that my installation fails in the put heatsink process.
i load PC alert and find CPU temperature in 78°C... oh, it's too high i think so shutdown the system and check the heatsink for anything that miss in the first time.
i put again the heatsink an log to the bios for check the values....
this is the values of PChealth option in bios:
   Cpu temp : 71°C and stable in this value...it's high too
   System Temp : 38°C ...high too
   VCore      1.744V
   +5.0V       5.038V
   +12V      11.923V
   -12V      -11.497
   -5V         -5.026V
   Batt      3.24V
   +5VSB      4.969
some ideas come to my mind and try to think if some options of the bios, the best performance option it's a good point to start i think so i select and save the changes...
oh, oh, the black screen comes again.... buuuuuu! and the four red leds too....buuuu!
mmmm, ....what i do?, what i do?....i reset again the bios, for the options and try to boot the machine again... maybe leave the system in the first point i think but nothing prepare me for the many "chorro" of errors thath follow after this point....
If i can roll back the time....
i think to be superman and fly in a oposite earth direction for roll back the time... (luisa!)
the system begins a non stop errors secuence sometimes the four leds are red, sometimes tree leds red an the top right led green, in the book says this signal is for damage DDR ram...
wen windows 98 loads the system frozes in some points, and wen enter and run some test the system frozes too...
i reset the bios to the original form an try to leave the house excactly wen enter the first time... i save it and the errors continues...
with NO hope of correct by myself the issues i turn on my old K6II system and find the MSI forum that got some mysql errors
in the forum find the Power unit suplly issues, i got the ATX box and 300W maybe it's too low i think after MANY post with same errors like me, i think to made a program plan for recover the stability and my ideas come in the next point.
now need another message to continue....

Return the system to the "normal" or less stability
In the forum (thanks for the people thath participate) some people says issues of frozen systems because cheap ATX power supply, some other got problems with the heatsink, i think that a mixture of those issues gotme like mad and try to figure out the quality of a atx power supply that changes the performance after a bios setup... ( it's a very cheap ATX power supply, i think) the Power unit now don't support the energy, and power needs of the system in some cases wen i run the 3d accelerated test the system frozes wen i hit "test".
return today to the computer mall passarella, and buy this items:
   Vulcano 7 (it's a building no, it's a airplane no,... it's vulcano 7 with speed sensor incorporated, much bigger than a building and more CFM than any airplane make!)
   ATX power supply 400W for kicks power requeriments and maybe extract energy enough for a reading lamp...
   wen come back to the house i install the new parts, the vulcano 7 needs the same mod than the other AMD one, or maybe MSI put the sockect A protect clip layer in the wrong site, maybe the board fit well in a ATX-XL case for no uninstall the power unit to put the heatsink... anyway need to uninstallit but this issue it's funny.
wen everiting it's ok i turn on the system...
KT3 Ultra Runs smooth... FINALLY
i know thath every body needs to listen a couple of help tips, in this point i think that logged to the forum are the best idea that i got, many people got the same problems and if you don't ask or search you think thath the MSI board it's a terrible board, and this no true, and because it's red too.
the system loads normal and i think to go up the FSB to the NORMAL 133 value for this athlon XP 1800+ i change the values, save and reboot the first thing that i find are the bios recognize the Amd Athlon XP 1800+ in the first black screen ( wen disables da logo) later, web hit windows key+ pause the window says Athlon XP 1800+, in the fuzzy logic app i find the values of 1523 Mhz and the temperature don't rises 50°C it's now OK, better than the cooking eggs thing that got before the changes.
now i need to give some thanks..
Thanks
to all the people in the forum, i don't write a nice english but i know read and it's enough for take a easy living style with this machines...
MSI people thanks
for the people in the mall, they don't know much the Power unit issues of this board it's a bit more exigent than others in his point.
to my dog that share my angry in the late night, it's a good one that dont' sleep well wen i work in the night..
so to all the people thanks for made this posible, maybe this long post with less technical things works for put your boards well.

MacBookPro3,1 runs well with 10.6.8 but can't install Mavericks or Mountain Lion

I have an old "Santa Rosa" MBP from August 2007. It runs 10.6.8 perfectively well but I thought I'd install Mavericks to see what the future is like. Unfortunately it failed midway through the install with a "hardware issue" message and a request for reboot. Fortunately it hadn't changed the OS on the hard disk so all I had to do was go into Startup Manager and boot the old installation.
I then tried to install Mountain Lion onto a USB drive and it gave the same hardware/reboot message. Curiously I can safe-boot into Mountain Lion.
I ran the Apple hardware tests and everything passes. The top of the kernel panic file in /USB/Library/Logs/DiagnosticReports/ reads:

One complication with the machine is that it had the NVIDIA cracked soldering problem. A year ago I sent the motherboard to a shop in California that put on a new graphics chip and it's run well since then although it reports 128MB of video RAM instead of the standard 256MB.
This model is supposed to run everything up through Mavericks. Is there anything obvious I've missed?

Time Machine Backup Fails - backup disk is unmounted during backup

I've been having trouble on and off with Time Mahcine backups. I have an iMac running Lion, an external USB HD which is my Time Machine disk. It will run fine for a day or so and then fail with the "Unable to complete backup. An error occurred while creating the backup folder". If I run the Time Machine Buddy utility it shows the follwing error log:
Starting standard backup
Backing up to: /Volumes/Media/Backups.backupdb
Error: (22) setxattr for key:com.apple.backupd.HostUUID path:/Volumes/Media/Backups.backupdb/Kitchen size:37
Backup failed with error: 2
Stopping backup to allow backup destination disk to be unmounted or ejected.
Backup failed because the destination disk was ejected or disconnected unexpectedly!
Any idea why the backup disk would be unmounted during the backup?

I have had a related problem.
Over the last three-four years of using TimeMachine I have had FOUR (4) disk drives fail on me. In the first instance, the power supply failed twice. Switching from connection via Firewire to USB seemed to solve that problem.
Then in May 2011 I bought TWO x Freecom HD 1 TB portable drives, I indicated to the Apple retailer, YooBee, expressly for use as TimeMachine backups.
They have both FAILED for me, as per the description below, which I have filed on the Freecom support site.
So FOUR disk drives failing over 3 to 4 years is beyond bad luck, beyond coincidence, but 'conspiracy' as Churhill might have put it. The common factor is that all four disks failed 'on watch' as being my TimeMachine drives. I am VERY ALARMED at his rate of failure, and wonder if there is a fault with TimeMachine in burning out the disks through some feature of excess use?
I note the detailed advice here is pertinent ... but I've only just found it!

I was absolutely assured by my Apple Mac (YooBee, 123 Broadway, Newmarket) store that these drives would be perfect for TimeMachine backup. But to have TWO fail within 8 months of purchase is very, very, very alarming. One failing is bad luck. Two failing is more than coincidence....
There was an alarming clicking noise from the disks.
Disks were disconncted from USB.
Message from Mac saying USB drive disconnected incorrctly. I DID NOTHING: Timemachine was just in the middle of doing a backup, perhaps. I was just working away when I noticed the tiny noise, above.
I turned of Timemachine in preferences. Physically powered down and disconnected Freecom drive. Waited. Reconnected. Unable to remount. Used Disk Utility to mount, and initiated Repair.

You can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can.
Well: the Freecom is not able to be remounted, even after plugging, and replugging the USB.
This happened with TWO drives.
And despite the suggestion to backup the files NONE are accessible.
This is NOT what I expect to have happen with drives expressly purchased for use as TimeMachine backups.
I managed to reformat the one that first failed, about two months after purchase. I have not attempted to reformat the latest failure-- and loose my complete Timemachine backup. Naturally, I don't use the reformatted disk for Timemachine, but a Vault for Aperture.

My internal hard drive no longer boots. Boots just fine in external usb enclosure.

My internal hard drive no longer boots when inside my laptop. The drive boots just fine in external usb enclosure. It is also fully recognized when internal (as seen in single user mode, recovery mode or while booting from another drive).
I have tried:
with disk utilities
•fixing permissions
•repairing disk
in single user mode
•fsck -fy
zapping the pram
removing ram and zapping the pram
Any suggestions or diagnostics would be appreciated.

Can't believe I spent days reformating my hard drive, restoring it, getting another hard drive... and it was all a cable that failed. I wonder what can make an internal cable like that fail (seems like the least likely part of all to fail).
Thanks PlotinusVeritas

"attempting to copy to [external drive] failed. the disk could not be read"

this is a problem on my 2x3GHz quad-core intel xeon macPro running os 10.5.7, and itunes 8.2. i have a 1TB external hard drive (firewire 800) that holds all my music for itunes. i have never had any problem with this setup before, until recently.
once, a while back i got an error on my itunes (that popped up without me doing anything.. seemingly random) saying something about not being able to save the itunes library. that went away after a restart, and hasn't returned.
BUT a new problem now happens any time i try to add more music to my itunes library. i have always added music to itunes by setting up my preferences "add file to library" and have the itunes library pointing to my external hard drive. then by dragging the files on-top of a playlist, it sorts and adds the files to my external hard drive. i have been using this process for years without any glitches.
now when i try to drag files into itunes, i get: "attempting to copy to [external drive] failed. the disk could not be read from or written to"
i double checked the read/write privileges on my external drive and nothing has changed since i got it. (it's still read/write access for my user.. and i've even tried putting a "read/write" for "all" as well. no dice)

thanks, that actually doesn't help the issue i'm having.
but now the problem has expanded to finder and everything else. so i'm pretty sure the external hard drive is starting to go out. i'm currently attempting to back up all 700GB of info from the drive.

My install of maverick failed as disk is damaged and cannot repaired. I tried to erase disk but got error disk cannot be unmounted. Please help. What can i do? Thank you very much.

First have you got a backup of your data? If not try to get one now while you have some access to the drive. The drive is probably faulty and will need to be replaced, without the backup you risk losing the data.
Have you a bootable external USB drive with Mavericks on it, if so boot from that and try and repair or erase the drive and reinstall Mavericks.
If you don't have Mavericks on an external drive, boot from you Leopard DVD ( I am presumimg your profile is correct) and run Disk Utility from there, you may be able to erase the drive and reload Leopard. You can then install Mavericks. Even if all that works you will most likely need a new drive in the near future.

I had the same problem. And to think I actually HESITATED at installing the update. Oh wait... this happened AFTER the update. Funny how often that happens, eh? But I digress...
Anyway, I had two errors- initially the iPod stated my music library was somewhere else, and did I want to sync to that library. When I said yes, it reverted then to the "attempting to copy to disk"error. Further, iTunes showed that my iPod on the iTunes was EMPTY. However, my actual iPod hadn't lost any data. Confused yet? So am I.
*Last ditch effort- I went back in, and updated all my permissions, did a permission repair and then a permission verify.
* Also did a disk verify on the iPod to make sure it wasn't sick.
*I also drug a new song into my library.
*Changed from the USB plugin to the firewire. (Although I did this earlier in the day, and hadn't seen a noticeble change)
* Opened the bottle of Sauvignon Blanc. (should have done that a few hours ago)
When my first pop up asked about did I want to sync to the mystery persons library, I said yes. (At the worst, I have all my music and could reimport all 30G of it, if necessary.) And immediately, the sync began, and began appropriately. However, it IS re-syncing every single song I had on the iPod to begin with.
I suspect something nasty happened in the iTunes update, ever since the intel thing happened, the updates have been a bit sketchy. I really like Apple products, but I've gone through 3 iPods due to software meltdowns, and it's a bit frustrating.
Good luck!

Time Machine failure: Disk run out of space unexpectedly

Hi
I'm having serious problems in the last few days with Time Machine backups.
I have an iMac '27 (late 2009) running Mountain Lion 10.8.2. The internal disk is 1 TB, and I use an external FW HD LaCie d2 Quadra 1 TB for my TM backups. After 3 years the disk is always full, but old backups were regularly removed. All the possible source of large variable files were excluded long time ago (VM disks, temporary directories, large download files).
TM used to work quite smoothly, but now, since 10 days, the backup fails with the message
"The backup disk ran out of space unexpectedly. Time Machine will try to make more space available by removing expired backups during the next scheduled backup."
I've checked previous messages in the forum about such an error, but the various cases do not seem to match my specific problem (or I was not able to find the message with working answer).
It seems that the "unexpected" problem is related to the fact that Time Machine is trying to backup again a large part of my filesystem, and it determines this fact only after the backup starts (so there is no pre-cleaning): when it happens I can see that the target size of the backup increases over time, while more and more data are written on the disk, until the disk is full.
I'll try to summarize my situations with an itemized list:
The current backup fails because it runs out of space, leaving an .inprogress file behind
The latest backup did not fail: the log report a successful backup (checked with Time Machine Buddy)
Examining the content of the latest backup, the one that did not fails, shows that some system directories, /Applications, /usr, and /bin are missing
So, possibly, the "unexpected" error happens because the system is backing up a lot of stuff (like 60GB), and TM discover this only after it starts writing the files
I've verified with Disk Utility both the TM disk and the internal HD, and they both report no problem.
After some digging around, I was able to make TM work again removing the .inprogress file (using the Pondini instructions), removing (using the "Star Wars" interface) the latest backup, the one with the incomplete content, and removing a few older backups to create some more free space.
The first time I thought it was a transient problem, but it happened again after a few days.
So the real issue is, why the latest successful backup is actually incomplete, with a large number of directories missing, but there is no hint of this in the logs?
I've read that old LaCie HDs might have problems with Mountain Lion, and with its power saving settings. May this be the cause? I did already turn off the power saving setting (put HD to sleep when possible) before the latest failure, but nothing changed.
I've also tried to update the d2 Quadra firmware, as indicated by other messages and on LaCie website, but the update fails and the provided instructions are less than useful (I'll try to contact LaCie on this issue).
My doubt is that this does not seem a power save issue... the failed backups happen while I'm actually using the machine (so no wake up/disk spin issue seems to happen), and the backups starts with no problem: they just finish abruptly with no apparent reason but with a success message.
Does anyone have problems similar to mine (successful but incomplete TM snapshots)? Is the problem triggered by the HD firmware, or there are other possible causes?
I plan to repair the TM one more time, and then keep it turned off to run only manual backups, but I'm aware that there is no guarantee that also a controlled manually started backup is not going to fail in a similar way.
Thanks for any suggestion.
Maurizio

I am not running out of space, but I do have the same problem. Every so often TM does a backup which is about 60 GB bigger than expected.   The extra is always a new backup of /System /Applications /usr etc. - that is the 'system files'.
The key thing is, as you have noticed:
Examining the content of the latest backup, the one that did not fail, shows that some system directories, /Applications, /usr, and /bin are missing
As a consequence the next backup is, in my case, 60 GB bigger because it includes all the system files.
It is as if 'systemFilesExcluded' was turned on for the previous backup (the one that 'did not fail'). But I have looked in the .exclusions.plist for this backup and it is exactly the same as for other backups and does include:
        <key>systemFilesExcluded</key>
        <false/>
It seems that TM is treating this as if <true/>.
Like you, I have done a disk verify and it finds no errors.
I think this must be a bug. I have had this on four occassions since upgrading to Mountain Lion. And it is doing a large one right now - I have caught it in the act!

I have a Macbook Pro 15" that is three and a half years old. Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?

I have a 250 gig drive and try to keep at least 100 gigs unused at all times, 4 GB 667 MHz DDR2 SDRAM memory, back up with Time Machine and CrashPlan, and have OS X 10.7.3.
This was my first Mac since an old Apple II GS. After that I used PC's and got really good at reformatting, replacing drives, reinstalling, defragging, resolving software conflicts, etc. Since switching back to Macs (five in my extended family now), I haven't had to do any of those things. So, although, the cost is three times as much, the aggrevation has been ten times less.
I'm retired and living on a fixed income and would therefore like to keep this computer running as opposed to constatntly upgrading.
That said, any tips?
Thanks
It does have a crack on the left of the screen case about 3/4'' up from the bottom. I've posted that as another question.

Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Adding more RAM, if feasible, and a new, faster hard drive may also help pep it up a little.

I have my new HD in a USB enclosure connected to my MacBook Pro and I want to put a fresh copy of Mountain Lion on it. But I do not have an install DVD as I got ML as a download from the App Store. What do I do?

I have my new HD in a USB enclosure connected to my MacBook Pro and I want to put a fresh copy of Mountain Lion on it. I'm told that I need to boot from the Installation Disk to start. But I do not have an install DVD as I got ML as a download from the App Store. Can I download ML from the App Store again, but this time directly to my new HD?

Create a data recovery/undelete external boot drive
You can also use Carbon Copy Cloner to clone your present setup to it and boot from it.

However, SOME external enclosures are not bootable, you will soon find out.
