I have a Seagate portable hdd 1 TB formatted fat32. Now I had no problems at the very beginning, but now I am getting the following error:

Error mounting /dev/sdb1 at /media/zorobabel/EFI: 
Command-line `mount -t "vfat" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,
shortname=mixed,dmask=0077,utf8=1,showexec,flush" "/dev/sdb1" "/media/zorobabel/EFI"' exited with non-zero exit status 32: 
mount: /dev/sdb1: can't read superblock
(udisks-error-quark, 0)

Same on ext4, and ext3 on 2 computers. Same on Windows.

Disks application displays: Partition Type: EFI System Contents: FAT32



$ sudo mount /dev/sdb1 seagate
mount: /dev/sdb1: can't read superblock

Therefore I no longer can access the data to backup, nor to format it.

$ sudo fdisk -l

sudo fdisk -l? – Braiam Jan 29 '14 at 20:49
I edited my answer. It looks like is visible /sda2. It cannot be mounted. – jazio Feb 12 '14 at 21:23
I don't see any sdb disk. BTW your mount command will fail since you should use mount /dev/deviceid /mountpoint you are doing it backwards. BTW, didn't you used sudo fdisk -l? with sudo? – Braiam Feb 12 '14 at 21:47
@Braiam sorry I did: $ sudo mount /dev/sdb1 seagate mount: /dev/sdb1: can't read superblock, where sdb1 is indeed visible at fdisk -l – jazio Feb 13 '14 at 19:20
Please edit your question and add the information. – Braiam Feb 13 '14 at 19:22
