Failure reading sector 0x9a2e8 from `hd0'

bad superblock on /dev/mapper/

If that is true, then try this method:

Bad super block

Reset language to default temporary: export LANG=C Check which device it is: lsblk --fs Get superblocks: sudo dumpe2fs /dev/sdXY | grep -i superblock Replace sdXY with your device. Check device with the superblock: sudo fsck -b <superblock> /dev/sdXY If successful, then also check for badblocks: sudo fsck -vcck /dev/sdXY

Of course you need to adjust it to your needs, but in general you need to test the superblocks until you reach a good one. This one will repair all other superblocks.

There is no logical reason to me for the fairly new disk to start failing.

Sometimes there is no logical reason. It could be just a “Monday model”, or how would someone say in English: a “Lemon”. A product which was produced on Mondays or Friday afternoons, when workers are not in their routine or just thinking of weekend.

However… there are 2 reasons for your problem: The HDD or the Filesystem… If it is just the filesystem, it should be easily fixable, if the HDD has failures than it could be difficult.
