I have a 12TB internal hard disk on my Ubuntu 18.04 workstation that when I boot, is assigned a 17MB 'Microsoft Reserved' partition and the rest is allocated to a second partition as free space (according to the Disks utility).
If I run fsck on the drive (i.e. fsck /dev/sdb), I get the following output:
fsck from util-linux 2.31.1
e2fsck 1.44.1 (24-Mar-2018)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
data2 was not cleanly unmounted, check forced.
Pass 1: Checking inodes, blocks, and sizes
Just running this, even without it completing, usually results in it being recognised as ext4 and mounted properly. However, if I reboot, the drive reverts to the same state as before with the Microsoft Reserved partition. This could be the result of the drive having been accidentally put into a separate Windows system, but I don't understand why fsck doesn't permanently resolve it. Unmounting the drive before reboot does not resolve the issue either.
Any suggestions on how I can permanently enable the drive to be mounted as ext4, without running fsck every time?
