Hi
Been having some funnies with my PC and then of course after a BSOD (Windows 10 system) it couldn't get an OS running, and just seemed to have lots of disk issues. I've now built a new PC and am trying to recover a few bits off it, but seemed to of got stuck at the first hurdle. When I boot the Gigabyte MB sees the 4 disks (And a complete raid 10 with no issues) and doesn't have any issue with the system, so as far as I can tell the raid never crashed etc... But when I use a Live rescue disk (testdisk or photorec) it just shows as 4 separate disks and not 1? As it's a motherboard hardware raid I didn't think I would need to install any other drivers for Unix to see it? or am I missing something (I know a bit of unix but not a heavy user). Any clues?

Re: Raid 10 - question
It's a software raid, try the following:
modprobe dm_mod
dmraid -ay
ls -la /dev/mapper/
Re: Raid 10 - question
Thank you, using Hirens bootcd and testdisk, instead of a unix live cd and test disk I have got slightly better results.
Initial output
What it finds (Looks about right I had a C OS drive, D Data drive and T Temp data drive)
But if I then try and list any files on the last (L) partition, I get can't open filesystem. Filesystem seems damaged?
PhotoRec does see lots and lots of files, but when I recover the filenames are not correct... so there seems to be hope somewhere!!
After a quick search I then get
At this stage I can deeper search or ... write
Do I go for it?

Re: Raid 10 - question
Well I seem to be going around in circles I've written the data, rebooted, but the same error occurs and no files can be seen (although photorec can still recover files fine but with the wrong filenames)
