Whenever i plug a usb (pen drive) drive to my system it doesnt mount and says "invalid mount option when attempting to mount the volume". Gparted, says to mount it to cdrom and can mount on cdrom but cannot create files even as root ...............
i tried a few things with no success, whose output is presented here..
surya@surya-desktop:~$ sudo fsck /dev/sdb
fsck 1.40.8 (13-Mar-2008)
e2fsck 1.40.8 (13-Mar-2008)
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
surya@surya-desktop:~$ sudo fsck /dev/sdb1
fsck 1.40.8 (13-Mar-2008)
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
/dev/sdb1: 0 files, 0/62735 clusters
surya@surya-desktop:~$ sudo pmount -w /dev/sdb1
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
surya@surya-desktop:~$ dmesg | tail
