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 Sense Key : Not Ready [current]
Filesystem is ext4.
"file -s /dev/sdc1" just hangs, no output, have to close terminal to stop the hang.
If you waited long enough, it probably would have stopped, but it looks
like every read attempt was taking 180 seconds to timeout. I'm pretty
sure your drive is toast, but you could try taking it out of the case
and connecting it directly to a SATA interface somewhere and see if it
works at all. It should at least timeout faster, I think.
