Weird Hard Drive failure problem

[IamZoot]

Well, I have this problem. My 7 year old computer has 4 SATA hard drives. The "C" drive is operating in RAID 0 and has the operating programs and the "D" drive is operating in RAID 0 and holds data. My external backup drive can only hold 250GB so considerable data on the D" drive could not be backed up. One day I was defragmenting the drives. The "C" drive defragged with no problems but part way thru defragging the "D" drive it stopped and said the array was broken. Not only that the computer would no longer boot and could not be coaxed into booting in any mode. To make a long story short it appears that the motherboard has failed. I know someone who has a computer with the same motherboard so we connected my "C" drive hard drives to his motherboard and it booted to Windows XP and operated fine. Then we connected my "D" drives but they could not be accessed. I ran the recovery software that I have and was able to get some of the data. What I got would about correspond to the amount that had occurred before defragmentation failed. If the motherboard failed while defragmenting was taking place can any recovery software address this problem or is it hopeless?

Keep in mind i post this with no actual experience behind me, other then knowing what RAID is and how to do it.

To me... it seems like it is hopeless, but then again, I wouldn't know for sure.

Are you sure you connected the 'D' drives the same way that the were connected in your old system?
Try using the same SATA channels. Watch your power cords - both drives should not be running off the same feed.
If using a disaster/recovery or undelete program does not work, I think you're SOL.
Most defrag programs run in 'safe' mode, they don't delete until the data is verified moved. Maybe your SATA drive buffers broke as the I/O was processing and the write came back with a false return.

Raid 0 if you loose one disc it will be alot harder to recover lost data, i like Raid myself but would have opted for 5 instead and a back up drive, try this link IamZoot Here depending on the value you have on your data, after taking Andes advice onboard,hope this helps, Raid 0 is great for fast read and write but not the safest option.
