Hello,

I'm trying to recover deleted files from a 10TB Raid-6 array on a Qnap TS-869 Pro NAS box. I've tried PhotoRec versions 7.0 and 7.1 beta; neither asks if it should analyze only Free space or the Whole partition. Instead both start analyzing the Whole partition which looks like it would take approx. 100 hours.

Am I missing something, or could there be something in the partition that prohibits analyzing Free space only? PhotoRec reports the partition as "P Linux LVM2".

Thanks!

PhotoRec doesn't ask Free or WHole because it's not an ext2/3/4... filesystem.

A disk contains several partitions, some of them may be LVM Physical Volume (PV).
PV are grouped in Volume Group (VG). VG are splited in Logical Volume (LV).
Each LV is formated (ext2/3/4, xfs...)

Your disk is using LVM, so you should boot from a Linux LiveUSB, use "pvdisplay", "vgdisplay", "lvdisplay"... and mount the logical volume or use PhotoRec on the logical volume instead of working on the physical volume.
