Hard-drive Raid 0 single drive failure

enigma_b17

Hi All

Just hoping someone can give me a bit of advice/help/assistance with an issue.

I have 4 3TB Seagate Barracude Drives in a RAID 0 software array done through Windows Server 2008 R2. Unfortunately one of the drives has failed and thusly the array has failed.

Can someone advise if there is either (a) a way to repair the failed drive, or (b) a way to recover some data on the drive (the array is still in place and I haven't deleted/formatted or reset anything as of yet.

I have backed up most things but unfortunately there were some things uploaded onto it recently that didn't get backed up, so hoping that someone can advise what to do.

Thanks

Raid 0 has no redundancy. Its gone

You want Raid 5 in future. Having 4 disks in Raid 0 is greedy, Raid 5 sacrifices 1 disk (virtually distributed) to provide Fault Tolerance, in this case you would just stick in a new disk and 3-24 hours later be back to full speed.

RAID 0 ouch.
If you are looking to get some critical stuff back off it then you are looking at a long tedious and probably fruitless task with some forensic file recovery utils.
Perhaps DiskInternals raid recovery but it would be doing well to work on RAID0, maybe if there was just driver failure or RAId corruption After that maybe something like recuva, diskdigger, or drivelook.
But unless it is critical crucial and financially invaluable, it probably isn't worth it.

Just reiterating what the others have said: Hard luck. You're bollixed. RAID 5 in future (or RAID 10 if you have the moola). RAID 0 with 4 drives = inevitable disaster.

Should RAID 0 be avoided lads?

Ive two SSD's running with RAID 0

If all you want is performance then no.

With 2 SSD's I would do RAID 1 myself. With properly implemented RAID 1 reads should be striped anyway (i.e. half read from disk A, half from disk B, so the same speed as RAID 0). Writes would be slower, but in general "who cares" applies there. You have very little chance of catastrophic data loss with RAID 1, at the cost of storage space of course.

If there is one thing that's a given though - it is a device failure, so plan accordingly.

RAID0 is really only a good option in very specialised situations, where both speed and storage must be maximised. If you want maximum storage, go for JBOD, then you only lose one drive if it fails
