Hard Drive Bad Sector marking utility [closed]

SpinRite from GRC is well known as a disk recovery tool.

It will scan all sectors, try to recover the data if possible and mark defective sectors so they're not reused. Worked fine for me in a few occasions.

It's not free though: $89.00


IIRC, all modern drives has the ability to mark some bad sectors & continue operation. I'm currently reading.
