I made a mistake when reinstalling ubuntu. In the installation process I did not mark my home partition as
usermod -d myusername:myusername /media/myusername
chown -cR myusername:myusername /media/myusername
# home partition
UUID=afce9d3e-7ce9-4cd6-91d2-77a0fa5c5a0a /media/ ext4 defaults 0 1
Not sure to have understand.
Before the reinstallation, you used to have a /home in a separated partition. After the reinstallation, that partition appears as /media/myusername. So, you personal folder should look like /media/mysusername/myusername. Correct ?
If not, than, before the installation, you used to have your /home/myusername on another partition.
In the 2 cases, I suggest you to mount your /media/myusername, either on /home (if in the first case), either on /home/myusername (if in the second case).
To make the mount permanent, you must add the entry in /etc/fstab.
Now, for the other problem of data not recognized, I suspect a file format issue. Could you give us the return of the command :
df -T ?
