I've had this 1 TB drive for about 1 year and have been using it succesfully for backups of my anf my wife's systems and suddenly yesterday morning I was unable to mount it. Neither fdisk nor gparted can see it but lsusb can:
Bus 002 Device 003: ID 0bc2:ab26 Seagate RSS LLC Backup Plus Slim Portable Drive 1 TB
On trying to mount I get this error message:
mount: /backupdev: cannot read the superblock on /dev/sdc1
Is the drive a brick or can I perhaps regenerate the superblock somehow?
That's a very bad sign. Check the journal to see if it's an I/O error or corruption. Which filesystem is it? What does "file -s /dev/sdc1" show?
From journal:
blk_update_request: I/O error, dev sdc, sector 5 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0 Buffer I/O error on dev sdc, logical block 5, async page read sd 4:0:0:0: [sdc] tag#20 timing out command, waited 180s sd 4:0:0:0: [sdc] tag#20 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE cmd_age=201s sd 4:0:0:0: [sdc] tag#20 Sense Key : Not Ready [current]
Filesystem is ext4.
"file -s /dev/sdc1" just hangs, no output, have to close terminal to stop the hang.
