Yes.

Yes, but you might making the disk worse.

Do a backup first.

You can try with the smartctl command:

to get status:

smartctl -a /dev/hdb

to run a test:

smartctl -t long /dev/hdb

Check status with "smartctl -a /dev/hdb":
...
Self-test execution status:      ( 247) Self-test routine in progress...
                                         70% of test remaining.
...

Wait for the test to finish, and look at the status of the test.

You could also try running the badblocks program.
