Recovering a raid 0 volume?

[ITtechy]

Hi,
So i have my computer running with a 120gb ssd as the boot drive and 2x 1tb hdds in raid 0 for the data. And today when i went to boot up my computer the raid 0 failed to start....both of the drives are detected but only one appears to be in the raid 0 volume. I know the disc physically still have all there data on them because i have not touched them. Is there any way that i can recover that raid 0 volume? i ask because i have data programs and complicated mk links setup to manage the files.....and yes i know i should have backups....... i have a asus p8z68-v pro gen 3 board with 8gb ram and a i5-2500k


Thanks

RAID 0 means striping. Both disks must be fine otherwise you lost everything!!
Both are detected... what do you mean... BIOS sees them?
Only one in raid volume.... maybe you mean something else but both are needed. Only one isn't possible.

Disks can die

yes bios sees both drives windows sees the drive that is supposed to be part of the raid volume but isnt...i guess i will be setting everything up again

You will be lucky to recover the data. RAID0, aside from being all about hype, was meant to give you speed, not data security. I have no idea why anyone would use a striped array for their data drive, considering how unreliable striped arrays can be. Your data drive should be reliable....especially if you don't have backups.

Hi,

Unfortunately, a RAID0 is a high risk stratgey for a data drive. I agree : it is highly doubtful you will recover any data as this RAID is not fault tolerant.

Do not follow the link in post #4 : this is thinly disguised advertisement for $99 software without any guarantee. Do not risk it.Original post #4 removed - thanks admin/mods

You might be better off without RAID and an external USB backup, or perhaps you might consider a RAID1.

RAID 0 means the Data is split across two discs, so the files are effectively halved onto each disc for quicker reading.

If one of your discs fails then both the discs will be useless as the data will become unreadable. Not sure if any Data recovery labs can restore it, but you'd be paying a lot of money if you tried it.

I have mine set up as RAID0 but I have two backups for each partition. I'm buying an SSD in a few weeks and shall be converting my two RAID0 drive into NON-RAID. You could use Raid 1 is much more reliable than Raid 0.

You wont recover losing a striped volume. With 2 disks it just isn't worth the supposed added speed. You lost one, you lost it all.

RAID 0 was intended to be 4 disks 3 striped and one as a recovery volume, if one goes down you can recover the data. Not with 2 however.

I never knew RAID 0 was intended as a 4 Disk Setup. Makes much more sense!

That sounds more like the definition of RAID5. With striping, there's no redundancy at all, so if one drives dies, your data is toast. In theory, the more drives you add, the faster it could be, but your chances of data loss increase at the same rate.
