I had an nvme drive formatted as NTFS on a dual boot 24.04 system which I thought was causing file system errors although even using a live USB showed it clean.

I decided to change the format to ext4 as ubuntu was the most used system. I copied al of the data on the drive to another nvme drive also formatted NTFS. Using Gparted I deleted the problem drive, remade and reformatted it to ext4.

Now in Gparted that drive shows:

Partition /dev/nvme2n1p1

Filesystem ext4

Size 1.82 TiB

Used 1.94 GiB

Unused 1.82 TiB

Examining the system:

The 1.94 GiB used is obviously wrong and I would like to correct it but don't know how. I do not want to replace the data if the drive is not correct.

Then I decided to mount on /media where all my other stuff is mounted. But I must have got the mount command wrong because all my 'stuff' show above has gone and I know not where!

I thought I was mounting it to /media where the other 'stuff' is.

Can anyone se where my stuff might be?
