Data recovery software for failed Raid 5 SCSI arrays

[oneilldo]

I was wondering if anyone had any experience of data recovery software for a Raid 5 array where 2 disks have failed.
(The Raid 5 contains 14 SCSI disks). Ideally want some software where the demo shows what files can be recovered and then
the software at a cost copies these files to another SCSI array. A quick google brings up a few choices but I wanted to know
if anyone has done this before and what software they used.

Thanks

The disks were for recoverable data anyway so not really a problem.
The array was a 14 disk Raid 5 array.
The array didn't have any hot spare configured but wouldn't have helped anyhow. Basically we are currently installing new UPS's onto most of the servers and had a power glitch. The server was on UPS but the array wasn't. When the array came back on line two disks were showing as failed (hence hot swappable not being much use). Managed to reseat both (then only one was showing as failed), then rebuilt that drive and all is fine.

Out of curisoity how many drives could you 'safely' lost in say a 10 disk RAID 10 setup.

So basically if two disks went in any Raid 10 setup you would be screwed.
If I am getting this then if you had a 10disk raid 10 array 5 disks contain the 'usable' data which is striped across them, the other 5 disks contain the mirror of the data so if two disks went you would be in trouble?

Thanks,

You had me confused then as I was sure you can safely lose more than 1 in raid 10 (well it will still work if you lost 2 drives depending on the drives)
