Internal Hard Drive Won't Boot or Mount

I don't know if this is the right forum for this but...
My 24" iMac running 10.5.2 won't start up. Meaning I can't get past the grey screen. I fsck the disk in single user mode and got back "invalid nobe structure (4,19621)" and repairs failed, then quickly shut down. As I understand it the (4,19621) means that the file with catalog node ID 19621 in the Catalog B-Tree portion of the disk directory has an invalid extent entry. I might be wrong here. If any knows how to correct that problem that would be helpful. But thats not the real problem.
I should add I tried to boot from the install DVD and repair the disk with disk utility and it would not repair the disk either.
Disk Utility recognizes the disk as "232.9 GB AAPL Firewire Target Media" and thats all while in target disk mode.
The real problem is the disk won't mount in firewire target disk mode. I would like to try to recover some of the fills that I haven't backed up mainly in my documents folder or repair this problem.
I am going to install (well not me) a new hard drive Monday and have a fresh and new system but in the mean time I would like to try to recover some of my files if possible.
I should add the one time it did mount, all the folders were there but none of the files. And it gave no worrying. I checked the S.M.A.R.T. status and the start up volume yesterday and got the report the disks seems to be okay.
Any help in getting the disk to mount in firewire target disk mode to repair and/or recover some files would help.

Thank you for the reply. That was the best and most logical reply.
DW never got to that point if thats what you are talking about nor did it get past "Inspecting disk" and Step 1: Searching entire disk in final rescue attempt". After hours of the beach ball spinning.
I am not within my apple care 3 years time frame. When they replace the hard drive tomorrow they said they might be able to recover some of my data in my Users folder.
Do you think that is possible?
That is more what I am worried about at this point. All of my important files have been back up there are just a few that weren't.
You confirmed what I was thinking. Thanks

MAC PRO HARD DRIVE won't boot

HARD DRIVE won't boot past APPLE ICON, grey spinning wheel on grey screen. Tried using install discs, no go past the icon.
Replace small battery inside? replace chips? Logic board replace as last resort. Can't take it away from work at this point to an apple tech.
Had just installed updates to snow leopard and was successful...but went to restart it...and this crap happened.
Thanks for any help.

I'll try that tomorrow. Thinking it could also be:
1) The PRAMM battery. found info on that they can wear out close to 5 years. This MAC PRO is close to that now. And I use a lot of power on it.
2) MAC PRO is plugged into a SURGE PROTECTOR, instead of right into the wall outlet.
3) Been doing a lot of FORCE QUITS and HARD BOOT -- unplugging it directly when it wouldn't shut down soon enough -- lately this past year.
I just assumed that this MAC PRO with the XEON QUAD CORE etc., was a heavy duty enough NLE,
that i wouldn't have these problems. It's not fully loaded with all the chips it can carry...and I don't have near enough external terabyte hard drives for storing video and audio files to edit. I've been storing wayyy too much
on the internal hard dives and just have to stop that.
I noticed these past few days that much of the LETTERING for hard drive icons and folders' titles
were starting to look in OVERLAPPING of the lettering. That was my first hint that something was up.

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).

G5 tower now boots, but one of the internal hard drives won't mount!

For those of you who saw my previous thread, my G5 tower would turn on and play the startup chime, then sit there until the fans ramped up. It seems that the problem was the Belkin PCI card. I removed it, and the machine started up with no problems.
Now, however, one of my internal hard drives (not the primary one) won't mount. Various programs can't even tell it's there. I'm completely lost as to how to solve this problem. My first thought was to try to swap it into an external case to see if it would mount that way. Thoughts?

One, possible two posts should read ground. Test for continuity against the metal case. Another should read 5V+DC. I think the four prong are: ground, ground, illumination then power. The connectors are gold plated and should not corrode, however, they are no match against fine particles of dust. You can carefully unplug both sides of the drive connections and vacuum. Usually, to unplug and re-plug is enough to get it to work again. When there no power coming off the logic board, you can find a Y-splitter and power off the other drive.

Internal hard drives won't appear in Disk Util

I have a bizarre problem with my hard drives now. I'm on a 2.4GHz Core2Duo Macbook Pro 15" with 10.5.4. I've switched the hard drive a couple of times before with no issues whatsoever. Now, with the exception of the brand new one that won't hold an install, my internal hard drives don't show up in the install disk's Disk Utility.
I got a new hard drive to try the other day, installed it, booted to my OSX install disk to use Disk Utility. I switched the new disk to GUID and formatted it as journaled like usual. It took 4 hours to do the install, then after the restart it tanked. It booted back to the install disk where I checked it out. It could not repair the file system, and the drive was not "mounted". I mounted it, repartitioned and formatted it, and installed again. This time it stopped halfway through the installation and said the drive might be corrupt.
I unplugged the cable and battery, held the power button for over 5 secs, then just let it sit for about 10minutes with no power source while I thought about this. I put the original drive back in, booted into OSX, and put the new hard drive in an external USB enclosure. I formatted it while in OSX, then rebooted into the install disk and installed OSX on it while it was in the USB case. It took the installation more quickly (about an hour and a half...still not 20min like my old 7200rpm Hitachi 200g), then I booted into its OSX while in the USB drive. It booted ok, so I downloaded the updates and clicked to install them. It then went into a revolving restart. Eventually I decided it was not doing this because it was happy so I shut it off.
I swapped the hard drive out with another new one, and this one would not complete an installation while inside the computer either. It acted similarly while in the USB case. HOWEVER it would always show up as unmounted after a restart and would not recognize the drive inside the computer as a bootable disk.
I put my original drive in there to give up, and it gave me the ? folder. I booted to the install disk and it did not show up in the disk utility. I put my old hard drive in the USB case, booted to the install disk, and it showed that it was there, but unmounted and it could not repair the file system.
I repartitioned my hard drive (i have time machine working..not a huge setback) in the USB case and put it back in the computer. It still would not show up in disk utility. I put it back in the USB case, installed OSX onto it (in about 20min), restarted a couple times, saw that it was working, put it into my computer, and got the ? folder again.
I went out and bought a stardard 160GB SATA 5400rpm Seagate drive to try in there, and this fresh drive is not recognized inside the computer either when I boot into disk utility.
The brand new hard drive WILL show up in Disk Utility when I boot to it from the install disk, but it will not survive a complete installation.
So now I'm running OSX from my original hard drive in a USB case until I can figure out why the old disk recognized inside my laptop is the new hard drive upgrade, but it cannot complete an installation on it.
I'm originally a Windows slave, so I can only think in terms of AHCI or SATA-card drivers, or screwed up bios. But this is all pre-os-boot, and the apple firmware seems to be pretty automatic in picking the right settings to see stuff.

I kind of feel like drawing a flowchart to show all that I've tried. Its difficult to keep everything intelligible while listing the entire last week's efforts at 2:45am. :-/
http://www.ocztechnologyforum.com/forum/showthread.php?t=41951
I also explained it here, perhaps a bit differently. Maybe some reply there might spark someone's memory of a possible problem. I understand the nature of computers (been 100% geek for 20 years), but I'm hoping there's someone out there with the specific Apple expertise to help me out. Eventually the processes I've taken and my specific situation will become clearer as the questions widdle away at this.
My original 7200rpm SATA drive that works fine won't show up when connected to the SATA cable. I've repartitioned it with HFS, and repartitioned it as free space in the USB enclosure. It simply won't show up in Disk Util. Same with the brand new test SATA drive.
The new SSD SATAII does show up, but after a 4hr install the partition is unmounted and won't show up as a boot option. I can boot to the install disk and repartition it, reinstall, or remount it. But it will never be mounted to be booted from while connected to the computer. I've had 2 of the SSD's to try, one survived one restart, then went into a never-ending restart cycle after I installed the updates. The 2nd has never successfully been mounted after the install to boot from. Now nothing can be mounted to boot from within the computer. I have to boot off of any of these drives from the USB enclosure.
If I install OSX on them while in the USB enclosure, that works, but they will not mount when connected to the SATA cable inside the lappy. The platter style SATA drives won't even be recognized...
Thanks for the instant reply, this is driving me nuts 'cuz it makes almost no sense. Thanks so much to everyone that contributes. I appreciate everything.

Why does dying internal hard drive stop you booting from external hd

Why do I need an internal hard drive if I am booting from an external drive? Doesnt make sense,
Disk Utility warned me that the internal hard drive is failing. I have managed to change start up disks. I have an external bootable drive and even have an empty partition on it, "just in case" I need to install a brand new OS, but here I am waiting for local disks, and I cant access my back-up OS.
Why doesnt OSX just move past the dying faulty hard drive and get to work on the bootable disk? Basically here I am supposedly doing all the right things to cover for an emergency - I may as well have no backup strategy.
Am I missing a step, or is this how OSX works. Perhaps if you read the steps and outcomes below, you can see if there is more I need to do?
If I press "option" at start up, it only shows the internal drive, not recognising the external bootable drive.
fsck -f produced a looping "missing thread" message that went on for an hour or more so I stopped that.
I tried the dvd and command-c at start up, got through to the installer window and when I selected disk utility it hung, but no spinning ball, just nothing was happening.
The next attempt with th DVD i changed start up disk, this time it saw the external bootable drive and I thought I was in business again.
And here I am full circle, waiting for local disks.
Any thoughts most welcome.
btw, does the SMART issue a warning of a failing drive because a drive is definitely unsalvagable due to a mechanical fault? or is there a chance my drive is physiclly healthy but shows as Failing because it has unbelievable directory issues that Apple tools cannot solve - but DW could?
PB Ti 867MHz 768MB RAM Mac OS X (10.3.9)
PB Ti 867MHz 768MB RAM Mac OS X (10.3.9)

The Bombich forums have helped me troubleshoot the integrity of the bootable volumes on my external hard drive which I made using Carbon Copy Cloner. The clones are fine ie after I reset nvram after booting up via command-alt-o-f, the clones are now recognised when I boot up-alt. So it seems that there was nothing wrong with the bootable volumes on the external drive per se.
However, the Powerbook will still not boot up past "Waiting for local disks".
As it stands now, nobody seems to be able to give a reason why I cannot bypass the failed internal hard drive. I found a Knowledge base article from Apple saying Cmd-Alt-shift-delete at start-up should skip you to the next working volume hitched up to your computer, but that didn't work either.
I have a new internal HDD coming, so prior to installing it, the final part of the troubleshoot will be to reboot the PB without an internal HDD. I will see what happens and see what conclusions can be drawn from that. Unless anyone has a clue now from what I have posted?

Internal Hard Drive Won't Load

Specs:
iMac Mid 2007 OSC 10.9.4
Processor: 2.8 GHz Intel Core 2 Duo
Memory: 4 GB 667 MHz DDR2 SDRAM
500 GB Hard Drive
So, my hard drive began acting funky about a year ago (would freeze at startup or freeze when trying to click on the Desktop). I restarted my iMac and loaded the installation DVD, using a USB-Hard Drive as my Startup Disk (I know, I know...). Ever since this issue I've just booted from this hard drive and made do with the reduction in speed from using a USB-connected hard drive, as there weren't any significant problems from going about this way.
Lately, though, applications have become significantly slower, to the point where loading more than one tab on Safari or switching from App to App causes the rainbow wheel to spin for a few seconds, forcing me to finally turn to you guys to see if you all could provide any advice.
I tried all the Safe Boot options/resetting the PRAM (at least, I think I've tried them all) and none seem to produce any worthwhile results. Even inserting the Install Disk didn't seem to help. I'm able to view my internal hard drive, launch applications from it, and so forth, but something seems to be corrupted/wrong with it being my Startup Disk.
I've tried Disk Utility to see the problem, and this is what comes up:
When Repairing Disk Permissions: nothing comes up...'Permissions repair complete'.
When Repairing Disk: "Error: Live file system is not supported".
My initial question (which will probably be revised once someone redirects me to what my main issue is) would be: Would I be able to completely erase my internal hard drive, repartition it, then clone my USB drive to this? Would that work the way I'd think it would? Or is the problem deeper than that?
Thank you.

The smart status is just the first thing to check, if you think there could be an issue with a drive. What I would do, if it was my computer. I would make sure all data I wanted was off the internal drive. I would then format the internal drive, and create a new partition. Then put a clean system on the internal drive. Use migration assistant to move the users, data and applications form the USB drive you have been using.
If I got errors, crashing or very slow functionality from the internal drive, I would look at replacing the drive.

Can I still take files off my current (corrupt) internal hard drive if I boot off an external?

Ok, here's what happened...
My MacBook Pro (2009 I think) suddenly started freezing recently. It would freeze for 10-15mins then work for 2 then freeze again. I opened the disc utility and attempted to verify disc- it failed and told me to restart and hold cmd+R which I did. From here I tried to scan the disc again, it told me to repair the disc. The repair failed.
Now, I have a TM backup from a month ago, but I've done a lot of writing in the last month that I'm desperate to keep. I tried restarting it again with the hope that even if it keeps freezing, I'll be able to get my work off before doing a system restore, but now it turns itself off before loading up.
I have the crazy idea that if I go onto the boot disc utility and download mavericks to a flash pen, then I could boot up off that and hopefully access my internal hard drive from within. Then I could find the work, email it to another location and TM restore the whole shebang. Is this even possible?!
It's currently downloading / installing mavericks on the flash pen.
Any thoughts would be greatly appreciated!
Desperate writer,
Jon

No. It is not an archival backup. It essentially is a mirror of what is on your hard drive. However, it will not delete those backups until it needs the space.
If you wish to archive them to other storage, you need to use something else (copying in Finder to an external would suffice).

Hard drive failure, new hard drive won't boot

Toshiba Satellite A665
I bought this laptop 14 months ago, last month the laptop refused to boot. It would say:
Isolinux disk error 05, ax4250, drive 9f
Boot failed
Often times on boot it would just show the black screen with a blinking underscore.
I tried all my known methods and nothing so I took it to a couple of shops. Both said that the hard drive was beyond repairable and not recoverable.
So I bought a new hard drive, installed it with the Toshiba recovery media. The recovery and install on new and drive went well. Had to restart, and upon restart, the original problem came up again- black screen with blinking underscore. I am unable to boot up. Any suggestions?
Thank you all

AHA, just fan issue?
Tukaine
Sep 23, 2012 10:59 PM
Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor.
Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable.
When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
Fixes people have used in the past included:
Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
HDD Fan Control
HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.
It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating
Instead of HDDFan Control, get the free SSDFan Control

My clone external hard drive won't boot - start up?

Hi,
I am selling my MacPro and need to clone its system drive for the new lap top I will buy soon. So I bought a new external 2TB HDD from OWC. I have found that this external HDD will not boot up, even though it says it is bootable, and appears in the Start Up prefs when I select it. It sppears on the desktop, doesn't make any weird clicking noises as well.
I am using 10.6.8 OS X. The 2TB HDD has two partitions (created with DU), one is bootable (Mac OS X extended journaled), and the other is a regular HDD space for media etc. It is GUID. It has "Ownership" checked in the info box.
I used CCC 3.4.4 and since this is 'hopefully' a one time deal, selected the 'Delete anything that doesn't exist on the source' setting. I cloned my system drive to the bootable space and had no problems with the transfer. Plenty of space to write all the files. I even made sure everything was checked in the 'source' window that a system drive might need. Everything was checked.
I spoke with a representive at the OWC Sales company and checked that this HDD can be used as a bootable drive.
I checked the connections: with external HDD with FW800, and Sata connectors. I have checked it with my Mac Book Pro as well. Same result. No boot.
I really don't understand why this drive won't boot, since everything looks correct.
Does anyone have any thoughts, suggestions, ideas for fixing this issue?
Thanks
M

Not sure if you managed to get this issue resolved yet Marcus, but I too have a similar problem:
Currently I'm upgrading from Leopard to Lion (via Snow Leopard) on both an iMac and MacBook Pro (both Intel), but before I proceed with the OSX upgrade I wanted to back everything up. Thus far I have partitioned an external firewire drive (G Drive - one that is bootable), and cloned each machine using Carbon Copy Cloner to it's own partition (both GUID). There is plenty of space left over on each partition.
The issue - I can boot the OS X from the external drive on the MacBook Pro but not on the iMac.
When I restart and hold down Option on the iMac the only drive that appears is the HDD, not the other two selectable drives that are visible if I boot up on the MacBook Pro. On the iMac in System Prefs > Startup Disc I can see all 3 drives but when I select it and restart, the machine freezes on the grey loading screen and goes no further.
Not that it should make a difference, but there is a 3rd partition on the external drive that is currently empty (for extra storage).
Any help is greatly appreciated - I can't find any relevant answers elsewhere. Thanks,
Dan

"Extra" Internal Hard Drives won't mount - swap, /, and /home work.

Hello All,
*** I'm updating my post finally. Sorry it's so long, I'm not entirely sure what is and isn't relevant.
*** Also I think it's a mix up with RAID causing the issue, as I'll address below, but in case I'm wrong I wanted to include the other information that came to mind before I noticed the RAID issue (because the RAID issue doesn't make a lot of sense to me).
First off, I'm running Arch64 and KDE4 with my system up to date. Also I have Gamin installed and not FAM. I use ReiserFS on all of my partitions and drives.
I have six hard drives in my computer, all of which are SATA drives. One is a WD 150GB Raptor with my swap, /, and /home partitions on it, the other five are for extra storage on what I call my media-server (they mount to /media/media-server/1 ,2 ,and so on). They only have one partition each. Of those five the first (/media/media-server/1) is a WD 1TB drive, the other four are WD 500GB drives of identical model.
All of the Raptor's patitions, swap, /, and /home mount just fine.
On top of that the 1TB drive mounts just fine. But the four 500GB drives will not mount at all. They show up in Dolphin, Disk Utility, KwikDisk, KDiskFree, and Partition Manager. However, their size is not shown and/or marked N/A, except in Partition Manager, where their size is shown. They are not seen by 'df'.
Output from 'df':
df -h
Filesystem Size Used Avail Use% Mounted on
udev 10M 308K 9.7M 4% /dev
/dev/sda2 25G 7.7G 17G 32% /
none 4.0G 0 4.0G 0% /dev/shm
/dev/sda3 112G 90G 22G 81% /home
/dev/sdb1 932G 919G 13G 99% /media/media-server/1
*** As for removable media, it's being a bit odd. When I first wrote this post removable media, specifically USB flash drives and SD media cards mounted fine. A while after that they'd show up in Device Notifier, but wouldn't mount. Just a little while ago they wouldn't show up in Device Notifier and wouldn't mount. Now they show up fine and mount fine again. This is possibly unrelated, I'm not sure.
Depending on what method I try to mount my hard drives I either get an 'only root can mount that' error or else a HAL drive busy or already mounted error, followed by a 'drive is not mounted' error when I use umount to double check.
*** Permissions are working better now , Dolphin isn't giving me the 'only root can mount' errors anymore. Still can't mount the drives though.
All of this output is from when the drives are listed in /etc/fstab:
Konsole output:

I have tried listing (with the UUID method and the /dev method) and not listing the drives in /etc/fstab, and I have 'hal' and 'dbus' daemons in /etc/rc.conf (and I've tried using only the hal daemon and not the dbus in /etc/rc.conf). I've also tried not listing 'hal', 'dbus', and 'kdm' and only booting to terminal and then mounting the drives manually, that doesn't work either.

I attempted to add the other drives to /etc/mtab but they get overwritten upon a reboot. I've drived mounting the drives from konsole and dolphin.
All my drives used to work. At one point I had Chakra installed and had this issue after an update, however after thinking about it the problem may have actually started after the power flashed on and off here. I couldn't fix it so I installed Arch64 and KDE4 (the normal KDE from the Arch repos, not KDEMod) thinking maybe it was a Chakra specific issue. That fixed it at the time. It later happened on my Arch install. I reinstalled Arch again and the issue was gone. However the issue is back. Again I think it was after a power outage/flash but it was also after an update that included a kernel update. Best I can remember each time it's happened has been after a kernel update and power flash. So I can't say for sure which is the cause.
Oddly though if I boot from a live disc (in my case a Chakra Live DVD) I can mount and access all of the drives just fine.
Another oddity, is that in 'Disk Utility' (palimpsest) there is a 1.5TB RAID-5 array listed. The only thing I can figure is that that is what is making the individual drives busy.
Here's a screenshot from Disk Utility of the RAID-5 array:
http://theavataroftime.com/sites/defaul … enshot.png
After talking to a friend I remembered that quite a while back (over a year) we had messed around trying to setup a RAID array and dual boot WindowsXP. However, we never could get it working quite right, not even just in Linux without dual booting. I really can't say what all we did/tried, it's been too long. I realize that's not much help but...
Anyway I'm pretty certain I deleted everything RAID related at the time and turned it off. However I must be mistaken or I guess the array wouldn't be showing up.
I apologize, I really know nothing about RAID or RAID controllers. I do have an onboard RAID controller, but it's not a full fledged hardware RAID controller. It's onboard, but doesn't have it's on proccessor like good hardware RAID would. Or that's the way I understand it. Perhaps 'hybrid' is the proper term?
I checked in BIOS and my onboard RAID controller is off.
I take it that my attempts at setting up a RAID array before are still in the MBR (on that note I use GRUB and have never used LILO)? That's the only place I can think of that any leftover RAID configurations wouldn't have been wiped during reinstalling and reformatting the drives and partitions? I've reformatted my drives completely and changed the size of swap, /, and /home on several occasions since then, as well as formatting the media-server drives to ReiserFS (not sure what FS I was using when trying to setup RAID before. Perhaps FAT32 since I was trying to dual boot).
I clicked the stop array button in Disk utility, and then all the options except start array went away. Then I clicked start, and instead of my four media-server drives being listed at the side of Dolphin there was one 1.4TB drive. I rebooted and now it's back to the 4 500GB media-server drives.
I'm worried about losing a bunch of data, so I'm hesitant to start experimenting. How should I go about getting rid of the remnants of the RAID array safely?
Also here's a screenshot of MediaServer5 from Disk Utility. The other 500GB drives have the same info minus the names and labels of course:

Thanks for advice on the matter.

Internal hard drive won't mount

First off, thanks in advance to any who offer help with my frustrating problem.
It would appear that my primary drive has come unmounted and will not remount. Yesterday I went to upgrade Corel Painter. The computer hung up when I launched the installer so I walked away from it for a few hours. Upon returning I found a screen telling me I had to restart. After the first restart I was looking at a Darwin command prompt (I don't know Unix, so this didn't help!). I restarted again and got the grey apple screen and a blue screen for a long time. I finally booted up from the OS X disc.
After unintentionally installing Tiger on my secondary internal drive I ran Disk Utility. My primary drive shows up in the left hand window, but greyed out. When I verify or repair the disk it tells me it passed verification and does not need to be repaired. When I try to mount the disk, it says "the disk cannot be mounted"
Looking at the additional info gives me this:
Name : Hard Drive
Type : Volume
Disk Identifier : disk0s2
Mount Point : Not mounted
File System : Mac OS Extended (Journaled)
Connection Bus : ATA
Partition Type : Apple_HFS
Device Tree : mac-io/ata-4@1f000/@0:2
Writable : Yes
Universal Unique Identifier : 0D681EDE-DA84-3486-AC05-16F7794AC9BA
Capacity : 28.0 GB (30,020,235,264 Bytes)
Owners Enabled : No
Can Turn Owners Off : Yes
Can Be Formatted : Yes
Bootable : Yes
Supports Journaling : Yes
Journaled : No
S.M.A.R.T. Status : Verified
Disk Number : 0
Partition Number : 2
I just don't understand what happened. This is the first trouble I've had since using OS X so I am lost in how to troubleshoot it. Any input would be great. I am a dummy and haven't backed up my drive in over 6 months so I am quite sad over this.

Have you tried mounting the partition from the command line? Even if it doesn't work, the command line sometimes gives more informative error messages. As a variation, the hint below describes how mounting a drive as "read-only" may sometimes succeed where a regular "read & write" mount might fail. If successful, it should be possible to pull files off for backup.
http://www.macosxhints.com/article.php?story=20041127045644235
In another approach, if you have an external drive that is big enough to hold the entire unmountable partition (or if your secondary partition has the free space), it might be possible to use "Disk Utility.app" to create a disk image of the whole partition - try selecting the icon for the unmounted partition in the left panel, then click the "New Image" button in the toolbar. After going through various prompts, it should create a disk image called disk0s2.dmg. I have read that it is sometimes possible to mount a disk image of an unmountable disk created using this process (unfortunately, I haven't been able to find a link).

New hard drive won't boot!

I have an iBook, and the hard drive recently broke. First I installed os x on my external firewire hard drive, but the iBook wouldn't boot off of it (it's a maxtor onetouch drive). I got another hard drive, and using the installer (for panther), I formatted the drive, and installed os x on it. However, the iBook won't boot off of the drive. What is wrong? Is it more serious than just the hard drive?

Well I just tried to boot off of the external hard drive (which is a Maxtor Onetouch firewire drive), while I didn't have an operational hard drive. However now that the replacement drive doesn't work as well (which I am more concerned about), I am wondering whether it is a more serious issue, or not. When I took it apart, I didn't see a logic board connector as in http://www.sterpin.net/uk/ddibookg4uk.htm (picture 43). It boots the installation cd fine, so I assume that there is not a problem with the logic board? The drive I purchased was completely empty, and I am wondering whether the boot part of the partition is wrong?
In disk utilities (in the installer), it does not see the new internal drive. I have tried to start up holding the option key, but it only has a screen with two buttons, and that ticking clock as a cursor.

Hard Drives will not boot or mount

I've been having problems with my hard drives (3) mounting over the last month or so. I had them on the SIIG Ultra 133/100 card. The drives would be on the desktop and working fine and then after a shut down or restart they would be gone. A pram reset seemed to get them back into service for awhile. Sometimes I would change the SIIG card to a different pci slot and that seemed to help. I asssumed that the SIIG card was going bad, so I replaced it. The new SIIG card will not mount any hard drives at all. I also attached one hard drive to the ultra ata on the mother board and it didn't mount. I've zapped the pram, reset the open firmware and replaced the battery. The computer will happily boot from any CD (9.1, 10.4, Disk warrior) but no hard drives are visible for repair or installation. All the hard drives were put into a firewire enclouser on my G5 and they boot fine so the drives are ok.
I have learned alot from these discussion forums over the last 10 years but I'm stumped on this one. Thanks in advance for any help. Steve

Do you know about setting an IDE hard drive to be a master or a slave drive? If you do, please forgive the lecture. But if you don't... When using more than one hard drive on a single IDE channel, one must be the master (In this case use the 9GB drive, since it's most likely the OEM drive) and the other must be the slave. You do this using some jumpers that are usually are on the "front" of the drive where all the power and cable connections are. (If they're not there, then the next likely place is on the circuit board of the drive.) There will usually be three or four jumper options: master, slave, cable select or single drive. The typical codes are: M for master, S for slave, C/S for cable select. The SIIG card might understand cable select, but the onboard controller doesn't, that's why you need to manually set it when you connect the drives to the onboad controller.
I doubt it's your power supply going on you since your machine still boots from the CDs.
Try a different IDE ribbon cable. If that doesn't work, check the voltage outputs on the power leads you connect to the hard drives. One black lead should be 12 volts DC, the other black is 5 volts DC.
If none of these ideas work, then I'd look at your logic board. But the more I think about it, the more I think it's your ribbon cable or the power cables.

New SCSI Hard Drive Won't Boot

Hello,
I have a problem. My original SCSI drive died on me and I took it out and converted over to only ATA drives. Ever since I did that, my computer has always been a bit lagging. Slow. Not too fast. Anyway, I bought another SCSI drive and I'm trying to use that as my boot drive. I used Carbon Copy Cloner and checked "make bootable" in the preferences, but for some reason my computer just won't boot from it. I've formatted it and it shows up on my desktop, but it won't boot. Start. Make OS go boom boom. I would appreciate any help I could get. Thanks in advance.

First of all, thanks for your reply. I appreciate it.
A couple of things. I check my system profiler and I couldn't find out what kind of SCSI card I have. I even opened up my machine and there wasn't any writing on it. So how do I find out what type of card I have? My other question is if the same card worked for the SCSI drive I had before, why won't it work on the new drive. I've set it as the master at the end of the SCSI cord and like I said I used CCC. The drive shows up on my desktop but won't boot. Should I try loading OS from disks instead of using CCC?
