Not quite a drive failure: course of action?

I have 4 5.6TB XServe RAIDs, and one of them just announced via the yellow "system indicator" light that there's a problem. Via RAID Admin, I learned that one of the drives is unhappy; it logged, roughly a dozen times over the last few days:
Warning Lower Controller 03/13/06 04:18:07 PM Disk 9 Reported An Error. COMMAND:0x37 ERROR:0x64 STATUS:0x81 LBA:0x19C65CD0
But the drive isn't dead enough for the hot spare to kick in. I have a spare drive module, so I could, I suppose, just pull the bad drive and let it rebuild onto the hot spare, and replace the bad with the extra drive module. But before I do that, I wonder:
* Is there any point in using the RAID Admin "Verify Array" feature here?
* Is there any way to decommission the drive module through software before I just pull it?
* Any other in-case-of-trouble-be-sure-to-do-this wisdom? The manuals are terse.
Thanks!

Pulling the drive is all you're going to need to do.
I suppose we were overthinking it all. So, as you might expect, it was quite straightforward to just pull the drive and pop in the replacement. At some level, I think we were hoping that you could first decommission the bad (but not yet failed) drive, so it would immediately start resyncing to the hot spare before we even had pulled the drive, just so that if something went wrong in the resync we'd still have the iffy drive available. At any rate, all's well that ends well.
The upshot of all this is that it remains surprisingly easy for a few software developer types, playing at being sysadmins, to be able to manage a handful of XServe RAIDs used with Linux (Gentoo Linux, no less) and LVM2.
Thanks, William.

IPhone 5 submerged in water, but did not turn off/will not turn off. Best course of action?

My iPhone 5 was just in the sink under running water and mostly submerged for a few seconds. It stayed on with all buttons working, clear screen and clear camera lens. I have tried to turn it off, but every time I try it reboots. I removed the SIM - it was completely dry, but since I can't see the inside I'm assuming there's definitely moisture in there.
I currently have it in an airtight bag with silica gel, and I'm planning to leave it for a day or two, but it's still on. Should I keep trying to turn it off, or is it better for me to just leave it? I don't have the necessary equipment to remove the battery, unfortunately.

Last attempt to turn phone off actually did turn the phone off. Not going to touch it for a day or two, and hoping for the best.

Hard drive crashed, best course of action?

I have a 2011 MacBook Pro. I have not had problems with it before this, but last night I opened it to work on something and it was frozen with safari open as is left it. I had a cursor and it's wasn't showing the spinning wheel but nothing was responding (ie the dock wouldn't pop up and quitting/minimizing or clicking anything on the top bar didn't work). I decided to restart manually with the power button. When it powered back on it showed a blinking question mark folder. I've looked this up and tried suggested fixes. Disk utility doesn't show my hard drive so I can't repair it, which I have gathered from other posts means my hard drive is probably dead. I did not regularly do any sort of manual backups, is there a chance I'll be able to salvage my stuff? What is my best course of action here?
Also, not as important but I'm just curious as to what could have even caused this as it happened out of nowhere.
Thanks!

seen countless HD "die out of nowhere" nature of the beast.
Grab yourself a new 1TB HD (not Western digital) and install same.
If youre not up to doing this, make an appt. with your Apple store for HD replacement.

Would cloning the drive be appropriate course of action?

Hello. I am considering purchasing my first Mac which is from liquidated stock originally owned by a film company. This is a new 2009 MacBook Pro 15.4" that will come loaded with quite a bit of high-end graphics software including Adobe CS4 Master Collection. The only issue is that the install disks for all the software are not included (we're talking about $4300 worth of software). I figure the company's IT people installed the software on the company Macs from the master disks. The software DOES include proper serial #s that have not yet been registered (according to the seller). I'm looking for a way to protect this software in case the drive fails as I won't have the disks to reinstall it. Would cloning the drive prior to using the MacBook be the appropriate and most effective way to do this? I apologize if this is a stupid question. Right now I'm using a PC and want to migrate to the Mac but do not want to spend the money on this particular Mac if not having the software install disks will create a headache in the future. (Other software preinstalled & without the installation disks includes: Aperture 2, Final Cut 2, Logic Express 8, Filemaker Pro 10 , Quark Xpress 8 and Toast 9 Titanium.
Any advice from the Mac community would be MUCH appreciated! Thank you.

Cloning the drive would make sense, but understand that this may not protect the software from requiring installers. Some software "knows" that it's been restored from backups and will require re-entering registration codes.
The seller of the computer should provide you with the original software installer discs or copies, and you should ask for them as part of the sale. Without them you may not be able to reinstall the software or get product support.
Making a clone of the drive helps, but it does not protect you against multiple drive failure or corruption that may render the drives unusable. Having installer discs is your best protection.

Rebuilding aMacBook 1.83 GHz Intel Core Duo, hard drive failure so rebuilding system. Aircard will not stop self-assigning IP address. Any ideas how to resolve successfully?

Had hard drive failure on MacBook 1.83 GHz Intel Core Duo, so had to rebuild the OS on new drive. Was on Lion 10.7.5 prior to failure, but had to reinstall Snow Leopard 10.6.3 since that was most recent OS on media I had. After finally getting ethernet connection to router working, was able to get to internet and download / upgrade to 10.6.8. I assume I can probably buy the upgrade to Mountain Lion 10.8 from there.
Problem is this, Airport will not stop self-assigning IP address for my wireless connection, and unless I can get wireless back on this laptop, doesn't make a lot of sense to continue the rebuild and reinstall of all the software that was on it prior to HD failure. Only way to my home network and router is ethernet now. Everything else on my network (Apple MacBook Pro laptops, iPhones, desktops, and non-Apple printers and laptops) is hooking up to router wirelessly fine.
Any ideas how to resolve successfully so that the airport will stop self-assigning and allow the router to assign the IP address?

My mid-2009 MacBook Pro has just died via a painful (for me) hard drive failure. I backed up a good percentage of files recently but not enough to keep me happy. I need to access the dead drive on the MBP via a 2008 iMac. Best options?
I have ordered a 800 firewire to 800 firewire cable and am hoping to use the target mode option to copy files from the MBP.
Is this possible?
Hope so!
Any advice and or help would be greatly appreciated.
Many thanks,

Thanks Ogelthorpe.
Just bought an enclosure to try that also.
Hoping the MBP isn't really dead but just feigning death
Fingers crossed.

Mac Pro 1,1 Hard drive failure... sorta. Then not.

I have a MacPro 1,1 Quad core 2.66 processor, with what I believe is the original 250 Gb hard drive. I'm running OSX 10.7.5.
Today when I powered it on, I could hear the hard drive spooling up (same sound as normal) then I heard 6 clicks and could hear the hard drive spooling down for a few seconds. It then spooled up again, heard 6 more clicks and it spooled down. Finally it attempted once more to spool up which was followed by 1 click and then spooled down with no more tries at booting up. Monitor showed blank grey screen until about the single click which brought up the grey screen with folder symbol with the question mark in it. I pressed the power button which turned it off. I tried powering up several additional times all with the same pattern of clicks and visuals on the monitor.
I did some research and tried to run the Apple Hardware Test by inserting the second of my original install disks and holding down the D key. Instead of bringing up the Apple Hardware Test, my hard drive managed to boot up completely with no clicks, and now appears to be running fine. I restarted and also did shutdowns... my Mac is booting up completely normally. I took the opportunity to make sure I have a recovery disk and the ability to download and install a new copy of Lion if the need comes up any time soon.
The main question is... was this likely an indication of a hard drive failure about to happen, as I tend to want to assume, or was the clicking sound and failure to boot a symptom of something else? Booting up while pressing "D" with the second install disk inserted shouldn't have fixed a hard drive problem... I wouldn't think. Also, anyone know the max size a replacement hard drive could be? I'll go with the same kind of hard drive as is currently in it, but not sure on if I'm limited to the original 250 Gb size.

I'm not sure I understand your reference to "clone and backup." I assume it's something else besides a standard backup done with Time Machine?
The main things to realise…
Clones are a static copy of an OS or disk.
Generally they don't have the history of older files (some can).
OS clones are usually bootable - a really fast solution to 'oh carp my disk died' moments.
Schedule one to be made as often as you can afford to lose data (e.g once a day, or every other day etc).
Time Machine is a 'rolling backup'.
TM copies new files, preens older stuff & then deletes when space is running out.
It also excludes some inessential system files (like logs) - technically you will not get an identical copy back from a TM restore.
Archives are for the occasions where you want to store on another media for permanent safekeeping.
These need to be capable of being read in whatever timeframe you need to store for (a year, a decade…)
Don't archive with proprietary backup software or proprietary media, otherwise you will have a tough time finding a machine to connect it to it & run the software.
Several copies on different disks, probably on different media too (e,g. HD + Flash storage + archival DVD's…).
You may want to revisit archives & duplicate them to new media once in a while depending on how important it is.
Ideally you would have some offsite copies to protect against fire/ theft etc.
If you are in business you need to employ all options, if it's just iTunes music & some family photos, you still need to employ 3 types of backup

Failure when connecting MS SQL SERVER from ODI ! could not load JDBS driver

i have some trouble with connecting MS SQL SERVER from ODI.
I have already downland jdbs driver 3.0 (and 2.0 ) and copy the sqljdbc4.jar to D:\oracle\product\11.1.1\Oracle_ODI_1\oracledi\agent\drivers( where the oracle jdbs driver is already exitst )....but i have this error :
could not load JDBS driver class..
thanks

After more investigation and even more chocolate, we've identified the problem and it's now working. For anyone else who strikes this problem in future, here's something to check/consider/try:
Even though Squirrel SQL Client was connecting and working ok using the MS JDBC driver (v 3.0), it recorded this in its logs:
Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AS" in the INTERSECT operation.
We've found that the open source jTDS driver does not have the same issue as the Microsoft one.
We've installed the current jTDS driver, recorded the driver name (net.sourceforge.jtds.jdbc.Driver) and the JDBC URL (jdbc:jtds:sqlserver://<hostname>:1433/<database>) and the connection is now working fine.
Hope this helps other people...
Thanks to those of you who offered suggestions and things to check...much appreciated.

Mini hard drive failure? What to do...

My Mini was exhibiting signs of hard drive failure: Lots of SBBODs, taking a long time to bootup (and sometimes not booting up), locking up for no apparent reason with only the mouse working, and making clicking noises like the hard drive is searching for something.
I ran Onyx and repaired permissions to no avail. Hardware check showed no problems. I ran Disk Utility from the setup disk and it repaired several problems (e.g., invalid leaf record, minor Bit Map repair, invalid volume free block count, etc.). It reported that my hard drive was repaired successfully.
However, the drive is still acting up. Strangely, when I jiggle or tilt the Mini while it's hanging, it will sometimes kick-start it. It looks bad all around. Fortunately, my valuable data is all on an external drive (250 GB MiniStack), since I use the Mini to manage my media and a PowerBook as my primary machine.
My questions are these:
• Does it make sense to continue using this drive by zeroing out the drive and reinstalling Tiger?
• Or, should I consider replacing the drive altogether (the tilting action makes me think it may be mechanical)?
Or course, my AppleCare expired a couple of weeks ago...<sigh>
Thanks in advance for any advice!
Best,
Amy

Sounds exactly like mine!
See if you have any friends with computers that could loan you a stick of 2700 or higher.
If I were closer, I would loan you my other stick from my PC.
Since your valuable data is on another drive...if you want to reload everything...
You can erase and reinstall OSX. If the drive is bad, it will have problems loading, then you'll know.
If it does load, and it runs fine, then the OS was somehow screwed up, but if it gives you the SBBOD again after the install and during software update or other intensive programs (like mine did) then I would suspect the memory.
Memory isn't used very much for the minor applications during the Hardware Test or booting to CD/DVD. Mine only showed up during actual OS booting and running programs, but since it's the easiest thing to replace and check, that's what I did first and it resolved my problems.

Possible Imminent Hard Drive Failure?

First off I have an Early 2011 MacBook Pro running OSX Mountain Lion. Avast version 7.0 is running as my anti-virus software with current definitions. I'm a network administration student so I run 2 or 3 virtual machines simultaneously to replicate a domain environment for learning. With that I decided I need space for all these operating systems plus my music and pics, so 10 Days ago I purchased a new Seagate 750GB HD Microcenter and upgraded to 8GB from 4GB of ram while I had the case open. HD has worked like a champ and the computer has been faster for days until last night. I was on Facebook and suddenly I got the spinning beach ball of death. Giving it the mac 3 the mac version of the three-finger salute didn't help me so I went for the hard restart. After that I got the blank grey screen. I restarted with the option key and all I saw was my Windows Partition, but when I tried to boot to it I got a kernel panic. So I went and got the OSX Mountain Lion thumb drive I made (didn't expect to be needing that so soon) and used disk utility. Disk Utility could not verify the disk and told me to format the disk and reinstall OSX. Knowing that I have everything recently backed up with time machine and Winclone I went ahead and formatted and restored my time machine backup along with my Winclone backup. (My attitude was, what were my options)
During the restoration process of OSX I had zero problems, while doing the restoration of my Windows partition with Winclone I was watching the console log and saw this.....

I'm not a beginner Mac user but I'm not an all-knowing genius of the Mac either, but I know the GUID has something to do with the file structure of the hard drive.... Either way after I performed the restoration everything seems to be back to normal. The same fast computer I had before with no glitches and disk utility has even verified my disk on several occasions now and hasn't reported any issues.
So here is my ultimate question? What would cause this random failure in the first place if not the HD? Is the forum's consensus that I should take the HD back anyways even though all checks are passing currently? And, if not the HD how can I prevent this from happening again? Let's face it, I'm a college student, I need my computer. Luckily it died when I was going to bed and I could let it restore overnight. Also, It's lucky for me that I didn't have class this morning and have no assignments pending that are immediately due so I can complete the windows restoration in the morning.
I'll be looking forward to everyone's insight.

Thanks for the info.
I just bought Techtool Pro last week when I my hard drive directories got chewed up the first time. The box has a "Tiger Compatible" sticker on it so I imagine it's at least v4.0.4 on the CD. (Although I will check now)
However, I think now the problem has progressed. Now the hard drive goes into a 1-2 minute cycling routine a couple times per day even if the computer is idle. Out of nowhere it starts up and it makes this repetitious reading/writing sound. It lasts 1-2 minutes and during this time the computer is hung-up (round-rainbow animated icon) and can't do anything, just have to wait it out.
At this point I'm thinking of calling it quits and I'm just going to take the machine in while there is still a warranty on it as I'm really starting to believe it's drive failure and not a problem with software.

Time Capsule hard drive failure

Hello, all
I have a 500 GB Time Capsule that is about four years old. I use it to back up my MacBook Air and I also use it for file storage. Recently the HD has become erratic, in that it appears on Finder under Shared sometimes but not always. The wireless router part is still working fine. I can usually get the HD to reappear but it disappears again eventually. I can get it back by unplugging and replugging the TC, but I tried a hard reset and that didn't bring it back. I have backed up all the files I had stored on there as advised by the Apple Store Genius (see next paragraph).
I took it to the Apple Store and the Genius said that he thinks it is failing. He was not able to see the TC/HD wirelessly but was able to access it by plugging in a cable. He expressed surprise that my TC has lasted four years!!! He said I should replace it.
I then went to the online Apple Store and read the TC reviews, which contained quite a few reviews that report HD failure (mostly power failure, if I'm not mistaken) after 18 months or so! Some suggested that a good solution would be to get an Airport Extreme plus a USB hard drive of some other brand, not Apple. Many of these report power failure, which is not my problem. I still have power; apparently hard drive failure.
This sounded like a good idea, so today I went to London Drugs in Vancouver (an Apple retailer) and the salesman there (should be fairly unbiased) thought I should get a new TC rather than the two-piece solution just because it was simpler. He also said that in fact there about three HD manufacturers who produce all hard drives and that any one would have about the same frequency of failure, Apple include because they don't manufacture their own.
So I'm ready to replace my old TC with the new one I bought, but I'd like to get any suggestions the community might have. I can see the advantage of the TC because it's an all-in-one. I haven't opened it yet, so I'll await your well-informed input.
Thanks so much!

I think the TC is a much better buy.. If only for this reason.. the USB hard disk on the AEBS is dog slow.. whereas the TC internal drive is at least same as standard single disk NAS.. overall for what you get the price of a 2TB TC vs the 2TB USB disk plus AEBS is about right.. the 3TB TC is much poorer value.
Read the review.
http://www.anandtech.com/show/4577/airport-extreme-5th-gen-and-time-capsule-4th- gen-review-faster-wifi-/4
It is fairly well done, but not everything is correct.. the stuff about the fan turning on is wrong.. it has the same issue as the old one. That is overheating, no ventilation and the fan does not turn on, has no outside vent anyway.
But look at the internal vs usb speed of hdd.. that should convince you of the value of the TC.. if you are using anything but wireless.
BTW the issue with the Gen 1 is still more likely to be the power supply.. The original 500GB hard disk was a Seagate Server ES drive.. the only server standard drive in the whole TC series although it was always promoted as having server standard drives..
IMHO a repair of the power supply would get it up and running again. Very extermely unlikely that drive will die in such a manner.. even if it was to go bad they tend to stay bad.. not come on again when you power cycle.. but power supplies sure do.
I have repaired dozens of them.. haven't ever come across a dead 500GB drive yet.. seen a few 1TB, both WD and noisy hitachi.. but even so not that many..
Lots and zillions of dead power supplies though.
https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair
At least you can pull open the TC and remove the hard disk and wipe it.
Interesting the Apple guys are surprised at the 4year life span.. obviously intended for you to buy a new one much sooner than that.

Hard drive failures after 10.6 installation, 2 library folders appear.

I have had to erase my intel imac hard drive 3 times and reinstall 10.6.
Each time the computer slowed to a standstill after a day or so, while using safari or mail.
It could not be repaired with disk utility.
After reinstalling 10.6 I have then retrieved the data from time machine. In all cases I had to update to OS 10.6.1 in order get my printer going (with the updated driver).
The odd thing is that when checking the hard drive trying to find out what is causing the problem
I noticed that it had
one library folder in the system folder
and another library folder outside the system folder
on the internal hard drive.
Is this the reason for the hard drive failures?
What should I do with this?? How could this have happened?
Please help! I've been using only Mac since 1986 more or less without any trouble,
but now I am having the kind of problems with SL that I thought only Windows users had!

HI,
"*It could not be repaired with disk utility.*"
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
*If DU reports errors Repair again and again until DU reports disk is repaired.*
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. *Where you see Capacity and Available. Make sure there is always 10% to 15% free disk space.*
There should be a Library folder in the System Folder.
