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.

  • 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.

  • 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.

  • It looks like one of the HDDs may have failed - how do I mount it and grab data off of it?

    That 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.

Being able to almost login to windowsXP does not sound like a failed drive in a raid0. When I have seen failed raid0 arrays there is no booting (hardware).

For the liveCD of Kubuntu, the proper driver (module) is not being loaded for the raid0 and Kubuntu is trying to read sda and sdb as separate drives. Sda is "working" since it has a MBR and sdb is failing since it does not. Your not able to mount /dev/sda1 since half of the data for your NTFS volume is on sdb which, is not being read.

How is the Raid0 being done? (software or hardware)

Run a chkdsk on the array, slipstream the sata driver into a XP install CD, then boot into recovery and run chkdsk /r from the command prompt.

I use this to slipstream the "Mass storage controllers" into a XP cd, no need for the other driver packs they offer in your case.

Clearly one of the drives is failing. You can't mount just one of the drives since it only contains part of the data; you have to mount the whole array, which is /dev/mapper/nvidia_ijdbffag1.

Your drive /dev/sda is failing. Already 1885 reallocated sectors is a clear sign of a dying drive. Check the health of /dev/sdb as well.

Duplicate your drive using ddrescue to avoid further degradation. Be aware that duplicating the drive will most likely further deteriorate the state of your drive. It may be necessary to duplicate /dev/sdb as well. With the striped layout of a RAID0 array you require two working drive for data recovery.
