Hi,

forgot to switch from AHCI back to RAID mode in BIOS after flashing, RAID got lost, has been deleted and rebuilt, but partition is gone now and I cannot manage to recover it.
Disk geometry seems to be odd, but I dunno how to tweak it so it might work again. Need help
Unfortunately I also wrote a wrong partition so there seem to be two now, where "Main" is the right one. Files from Main are readable and almost uncorrupted.
Any idea anyone?

Can you try PhotoRec on this Raid0 ? Does it recover valid files or only small files or file fragments ?
