I have a Seagate drive with some bad sectors.  I tried a low level format but that did not fix the sectors.  Is there some way to mark or isolate the bad sectors so the disk will not try to write data to the bad sectors?  A method involving a reformat is OK since the disk is now empty from the low level reformat.

Formatting...identifies bad sectors and marks them for non-use.


If Windows is installed already and data winds up on bad sectors...the chkdsk /r is the Windows tool for marking such,  attempting to move the data on such to good sectors.
