Not Cost Effective

by TheChas In reply to how to go about to resear ...

There is a very good reason that no one does hard drive sector repair. The repair costs more than a new drive!

There are 2 ways to deal with bad sectors.
1. Mark them as bad, and do not use them again.

2. Open up the drive, replate, or replace the platter(s) and re-assemble the drive.

Software can handle option 1, and the clean room and plateing equipment make it costly to implement option 2.

Doing anything less than option 2 may get some additional life out of the drive, but puts you at risk.
Generally, once 1 sector goes bad, the rest of the platter begins to deteriorate. It is only a matter of time until the drive is un-reliable.
