I would check the health of your disk(s) with this command:

sudo smartctl -i /dev/sdX

Where X corresponds to the disk you want to check.

Is the output of smartctl -a does not show anyth ok NG bad you can perform a SMART test just in case:

sudo smartctl -t <short|long> /dev/sdX

Where short or long is the type of test, one take
s a few minutes, the other may take a couple of hours.

You can then check the test results with:

sudo smartctl -l selftest /dev/sdX

Can you remove sdb? can you delete it from your fstab?
