Hi
using e17 to mount pendrives
jls@pc2:~$ sudo /usr/local/bin/mount -o noexec,nodev,nosuid,uid=1000, UUID=543f873e-8c03-43e0-8f78-40283ccf065b /media/sdc2
mount: wrong fs type, bad option, bad superblock on /dev/sdc2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
looking at dmesg:
EXT4-fs (sdc2): Unrecognized mount option "uid=1000" or missing value
