A friend asked me to wipe/format a 2TB external HDD. It just doesn't work.
With lsblk -l
I can see the disk which is formatted in NTFS and mounted as /dev/sdg1.
I tried mkfs.fat /dev/sdg1
, resulting in mkfs.fat: /dev/sdg1 contains a mounted filesystem.
sudo umount /dev/sdg
just takes forever and nothing happens.
Then I tried dd if=/dev/zero of=/dev/sdg1 bs=1M
, but again, nothing happens. No output; all I can do is close the terminal window and terminate the process.
Finally I entered sudo gparted
. The program keeps loading until I plug out the external HDD, only then it shows my computer's SSD.
I've never had this problem with any hard drive before. Any ideas?
/dev/sdg: Unknown USB bridge [0x0bc2:0xab26 (0x108)] Please specify device type with the -d option.
