Hi Lizzy,

I have 2 TB Seagate hard drive and it is working fine, but some of the folders stored in the drive are not accessible. I think it is because of bad sectors. Can you please tell me how I can fix bad sectors and access those folders.

Hey Anon -

Have you tried plugging the hard drive into a different computer to see if it works on a different machine? 

If it does work, you can try rolling back the update(s) on your primary computer, reboot, and try plugging it in again.

If it does not work, then something might be wrong with the drive.
