My machine is as follows:
- Pair of hard disks in RAID0, ATA Hitachi HDT72505
- nVidia motherboard, "M51"?
Windows XP refused to boot:
- Booting normally results in hanging during the Windows loading screen
- Booting in safe mode, it is able to reach the login screen. Logging in results in hanging.
Using the Windows XP installation CD:
- Does not detect any of the hard disks
- If an external HD is plugged in, then the CD will mount that HD while using the Recovery Console
Luckily, I have a DVD of Kubuntu 9.10.
fdisk -l shows this output:
Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xc0cfc0cf Device Boot Start End Blocks Id System /dev/sda1 * 1 60801 488384001 7 HPFS/NTFS Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xfff7fff7 Device Boot Start End Blocks Id System Note: sector size is 4096 (not 512)
Note that there is no device shown under /dev/sdb. Kubuntu did not automatically mount the hard disk.
Trying to do: mount -t ntfs-3g /dev/sda1 /mnt/windows results in mount complaining that ntfs-3g: Failed to access volume '/dev/sda1': No such file or directory
The Kubuntu installer cannot determine how much of the hard disk is used by the NTFS partition, either.
I am currently running: smartctl --test=long /dev/sda but am not sure what the output will mean
Update:
This is the output of dmraid -ay -vvvv -dddd

RAID0 Failure? Never! Honestly, what are you trying to diagnose? That's the title of your question, but you never specify. If I were you, I'd just reinstall (this time on RAID1), restore from backup, and be done with it. – EEAA – 2010-11-02T01:33:27.300
I'm trying to figure out exactly what's wrong, so I know how to proceed from here. Also, I'm not sure how to backup the data from the drive since I can't even mount it. – None – 2010-11-02T01:38:08.293
If you're unable to mount it, it's fairly likely that it's too late. You may not know this, but RAID0 actually doubles your change of losing data due to hardware failure. Data is striped across both disks, and all it takes is a single drive failure to take the whole thing down irrecoverably. Next time, try RAID1, 5, 6, or 10. – EEAA – 2010-11-02T02:05:21.157
It looks like one of the HDDs may have failed - how do I mount it and grab data off of it? – None – 2010-11-02T02:46:53.913
That's the thing. In a RAID0, if you have one drive fail, all the data is lost. When you write files to a RAID0, files are striped across both disks. This means that when you lose one drive, you're (roughly) losing half of each file, which even if you could recover, you'd not be able to do anything with. This is the reason that I never recommend RAID0 for any application. – EEAA – 2010-11-02T02:53:22.660
I suspect that unless the whole thing can't spin anymore (which it still can) a few bad sectors, probably where the OS used to be, cannot cause that much data to be permanently lost! – None – 2010-11-02T03:10:36.110
1That drive (/dev/sda) is clearly bad, as smartctl said. Not only are files split between drives, but also the filesystem's structure and metadata are striped across drives. This is why you're unable to mount it. If you really need data off of it, you better contact data recovery professionals and be prepared to fork out a lot of money. – EEAA – 2010-11-02T03:21:50.310
I disabled RAID in the bios, thus allowing access to the individual HDDs. Then I was able to do some quick scans with 3rd-party tools. Although I still ended up having to contact professionals, I saved at least $100 by getting this far on my own. – ssfsx17 – 2010-11-03T00:13:12.237
