Your hard disk is failing. We can try a few things, so keep your fingers crossed. You have two partitions on your hard disk, and both partitions are having problems, which suggests a problem with the MBR partition table, or just the hard disk failing in a very complicated way. You may have to replace the disk drive.
This is a file system check. It's the first step to try and diagnose and repair your disk. If we can't get it to run successfully, we'll have to go to the
For 17.10 or older...
sudo fsck -f /
fsckcommand if there were errors
For 18.04 or newer... (or if the above steps don't work for you)...
terminalwindow by pressing Ctrl+Alt+T
sudo fdisk -l
sudo fsck -f /dev/sdb1, replacing
sdXXwith the number you found earlier
fsckcommand if there were errors
fsck can't be run successfully, we'll try the Check option in
/dev/sdb1. Go to the Partition menu and select Check.
If that's not able to fix the errors, assuming that you don't have good data backups, we'll attempt at recovering your data.
gparted, go to the Device menu, and select Attempt Data Rescue. Follow the instructions to try and copy your data off to an external disk drive.
As a last ditch effort to repair your hard disk, we'll try to bad block the disk, as you do have some bad sectors on the disk. This may fail, and leave your disk in an unknown state.
Note: do NOT abort a bad block scan!
Note: do NOT bad block a SSD
Note: backup your important files FIRST!
Note: this will take many hours
Note: you may have a pending HDD failure
Boot to a Ubuntu Live DVD/USB in “Try Ubuntu” mode.
sudo fdisk -l # identify all "Linux Filesystem" partitions
sudo e2fsck -fcky /dev/sdXX # read-only test
sudo e2fsck -fccky /dev/sdb1 # non-destructive read/write test (recommended)
The -k is important, because it saves the previous bad block table, and adds any new bad blocks to that table. Without -k, you loose all of the prior bad block information.
The -fccky parameter...
-f Force checking even if the file system seems clean. -c This option causes e2fsck to use badblocks(8) program to do a read-only scan of the device in order to find any bad blocks. If any bad blocks are found, they are added to the bad block inode to prevent them from being allocated to a file or direc‐ tory. If this option is specified twice, then the bad block scan will be done using a non-destructive read-write test. -k When combined with the -c option, any existing bad blocks in the bad blocks list are preserved, and any new bad blocks found by running badblocks(8) will be added to the existing bad blocks list. -y Assume an answer of `yes' to all questions; allows e2fsck to be used non-interactively. This option may not be specified at the same time as the -n or -p options.
This extended partition is also having problems, and the partition is empty, and can be deleted, using
The HDD is defective. Replace it.
