New Info! As per your direction, I re-read your original post (d'oh!). I opened Files, and noticed an empty folder called 'rescue', I I tried sudo mount /dev/vg0/lv0 /mnt/rescue and I got mount: /mnt/rescue: special device /dev/lv0 does not exist. Hmmm, I'll look again, with authority: user@BOB-II:/...

I tried to mount /dev/md126 and tried to mount /dev/vg0, but both times I get 'can find in /etc/fstab'. For pity's sake! I'm just tryna get my data back.

Thanks to gparted, Ubuntu now "sees" three of the four partitions on the HDs from the NAS as cohesive units /dev/md126, /dev/md126, and /dev/md127. It looks like /dev/md126 is the big one, with all my data, but I don't want to flock it up trying to mount it incorrectly. I suspect that sudo...

The HD with the DATA folder on it seems to be /dev/sda

I cannot locate the DATA folder in Files, though. Dunno why.

It seems the new HD is /dev/sda, which has the directory DATA (in theory).

However, if I open Files, I can locate neither the HD, nor the DATA folder. I do not understand how Files works (makes me long for DOS).

As far as my noob self can determine,the empty drive is /dev/sda The first of the four former NAS HDs is /dev/sdb1, /sdb2, /sdb3, /sdb4 (/sbb4 being the biggest partition, by far). The remaining HDs are /dev/sdc1, etc. through /dev/sde4. I tried ddrescue, but it failed after 30 hours as there was no...

I notice that all four HDs have partitions that share mount points, and are linux raid members. /dev/sdb /dev/sdc /dev/sdd /dev/sde Every one of these has four partitions that each have the same mount point (/dev/md125 or 126 or127). The largest partition on each is /md126, /md125 is the TOSSWAP (TO...

I'd added a new HD to store all 17TB of data, and created a folder on it called DATA. I tried mount /dev/vg0/lv0 /mnt /DATA, but got mount point does not exist.

I can mount the TOS_VOLUME_2021-, but none of my actual data are there, just some TerraMaster program things.

Puzzling.

Thank you; this seems promising. Sadly, my days of frolicking in the command-line are many years past. As such, I'm not sure what to make of the output of the suggested commands: root@BOB-II:~# pvscan WARNING: PV /dev/md127 in VG vg0 is using an old PV header, modify the VG to update. PV /dev/md127 ...

I've removed the drives, rebooted everything, bought a replacement firmware flash drive from amazon, and have exchanged more email with terramaster support than I can count. It does not work. TNAS PC was never able to find the F4 again, even after re-installing it. This is the replacement F4 Terrama...
