Raid 0 Failed (Intel Raid Controller) Help Needed

post #1 of 15
Thread Starter 
Ok so my sig rig blue screened today. I went to reboot it and then it gave me a file missing error before it boots W7. I reboot and check the intel raid, 1 drive (out of 2) was no longer in the array! After alot of messing around I found out it seems my SATA Port 1 died so I moved the drive to a new port.

The thing is I had deleted the array and recreated it with the same exact settings. Is my data lost?

Currently I am on an ubuntu Live CD and hoping my data is recoverable. Theres not much I'd lose but it seems my backup failed and I'm still missing some school work that I would like to retain and a few other files.

yes, once you delete the array, it forgets where everything was on the drive...it's all still there until it's over-righten, but you can't access it now...you'd have to do some kind of data recovery, but I'm not sure how or if that works for RAID0

I figured I screwed myself.

I used some software before at work, it was SLLOOOWW but I guess I'll look it up and give it a shot.

If you didn't reinitialize the array, you *might* be lucky because the blocks haven't been overwritten.

The RAID metadata is stored on the HDDs. Personally, if it were me, I'd reinstall Windows on another HDD, and then get the new array up and running and then use a utility such as EASEUS Data Recovery to try and see if I'm lucky to recover data from the block level...

Re-create the array as it was, and then use testdisk. If it fails, use photorec.

This.

You should recreate the RAID array with the drives in the EXACT same order as they were in before. As long as you didn't re-initialize the new arrays you should end up with your data exactly the way you left it.

How do I know if it initialized. Im more used to the perc cards at work. I'd assume the intel one would just initialize it anyways.

I still have my raptor laying around so I'll reinstall to it.

Thats where I am at now. Currently windows is installing on another HD.

For test disk should I run the windows version or just go with a Live cd? If I go with a Live CD which one should I pick? http://www.cgsecurity.org/wiki/TestDisk_Livecd

EDIT: I'm going with the Ultimate Boot CD since it includes Test Disk. Seems my W7 disk was a bad burn. I'm gonna have to get another copy from my schools MSDNAA the speeds are just slow tho.


UPDATE: Ok I got test disk running, it mentioned something like it didnt find the end of the partition so now its analyzing the cylinders.

Photorec is pulling data off the array. Hopefully all my data is there, it seems the partition is screwed due to the array problems.

I'm gonna check out some of the other programs listed in the thread to see if I can get something that lets me select data off the drive.
