Hard disk seems too small

#1 Post by quadrapoole »

Hi everyone,

I had an unclean shutdown of unraid and now my nvme drive can't be mounted.

I used test disk and it found the partition I want to recover when I used deeper search and it says that the hard disk seems too small!!

I'm pretty sure I need to adjust the cylinder in the geometry tab.

Can someone please help let me know what I should set the cylinder at to make it work?

My wife is so mad at me rn. :(

Re: Hard disk seems too small

#2 Post by quadrapoole »

I fixed it by just plugging the disk into unraid and unassigned it as a cache drive.

Turns out unassigned devices can read the drive.

I think it was unraid that messed up the file system. I tried to format it as XFS but it didn't do it properly and was still btrfs.
