Problem with thumbnail cache

[Muru]

running fsck gives this:
sudo fsck /dev/sda1
fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
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/sda1

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>

Can you give us the output from (lines with a hash are comments only, not commands)

sudo fdisk -l

# that's an l for list

No Bios upgrade available at Lenova support. They only have them for Win 7 and 8.

Well that all looks OK.

The bad magic number and invalid superblock references above are because you were trying to run fsck on a partition which is not EXT formatted.

Is everything else working OK?

Off and on. By now I had to reboot twice, with the same problem coming up, ie. the drives turn 'read-only' and block any copying or downloading. Earlier this was not affecting USB drives. But since yesterday that too has started. Is there any other app other than Smartctl to check the hard drive?

 

[wizardfromoz]

Beyond my paygrade, I am afraid.

Someone else may have the information.

Hope it works out for you.
