I have a 2TB flash drive that was corrupted when I pulled it out without ejecting it first. I am trying to erase the files, delete the partition, and reformat the whole thing. All the obvious things are not working though.
Disks couldn't overwrite the data because it's read-only, GParted has 2 things it will do, if it's already unmounted then GParted simply crashes, if the drive is mounted, GParted will open and then crash when I unmount it. I even attempted to use unetbootin to overwrite the files with an Ubuntu iso and it didn't work. I tried changing the files to read/write but that didn't work either. Any suggestions?
$ sudo fsck -n /dev/sdb
fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
ext2fs_open2: Bad magic number in super-block
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 valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
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>
or
e2fsck -b 32768 <device>

The usb says it is a Transcend but I think it's a knock off, it shows up in the results linked above as generic mass storage.
