Can't read superblock on HDD partition

[megavolt]

And got this output: smartctl output on superblock issue - Pastebin.com

Important are these lines to detect errors:

  5 Reallocated_Sector_Ct   PO--CK   252   252   010    -    0
  7 Seek_Error_Rate         -OSR-K   252   252   051    -    0
 13 Read_Soft_Error_Rate    -O-RCK   100   100   000    -    0

So the Raw values are ZERO, so no physical problem here.

But the errors below look like a loose contact or defect cable. Consider to check this.

Ultimately I want to know how to fix this issue so that I can, again, be able to mount /dev/sda13 (I mean, assuming there hasn’t been an unrecoverable hardware failure)

So I assume it is a corrupt filesystem because of a loose contact. Here is a short explanation if it is EXT4 filesystem:

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
