Corrupt data on RAID5 drive after Windows 2000 autochk
Hi
I have a windows 2000 desktop. The OS runs from an IDE drive, and I have 3 SATA drives setup with RAID5 for data storage.
Yesterday one of my RAID5 drives failed and I had to remove it from my PC. Before OS boot the nvidia mediashield software flagged the drive as 'degraded' but recognised the remaining 2 drives. Windows booted and I was able to see the RAID5 drive still and access the data. I know from past experience when the 3-drive RAID drops to 2 drives that you can access the data, but it is not a good idea to save to the drive, as the data will be corrupt when you rebuild the RAID back to 3 drives.
Anyway, it all seemed OK. I booted my PC again today, left the room and came back 5 minutes later to see the windows 200 chkdsk/autochk just finishing, and saw references to deleting orphan files on my RAID drive.
Now in Windows, I can see all the data but it is basically corrupt. An MP3 will play, but it skips and jumps. A video will play but it too will skip and has distortion in the picture, ISO files wont load because of they appear corrupt.
While i have loads of data, things like music I can re-rip from CD. However I have things like my digital photos from the last 4 years, which I dont have anywhere else. Some load, some dont (I know I should probably backup but that was why I setup RAID 5 in the first place).
I have read other articles on here about trying to undo the effects of chkdsk, but these relate to missing data. I kind of wish I was dealing with missing data because I have been able to successfully do this in the past.
I am currently running a full scan using EASUS Data Recovery (3hrs remaining) and will see if that can help (http://www.easeus.com/datarecoverywizard/recover-scandisk-chkdsk-disk.htm) but does anyone have any ideas how I can undo the effects of the chkdsk or fix the corrupt data somehow.
Thanks
