The only exception is a secure erase by ATA command. You need to write either the pending sector (you can find out were it is by running a full SMART test, e.g.) or write the whole drive. AFAIK windows cannot do that itself, look for one for the various disk erasers. Arno -- Arno Wagner, Dr. sc. techn., Dipl.

No. It reads all sectors and tries a recovery and reallocation for those with problems, but it will only reallocated if it can read the data. I think the current version of HDD Sentinel can do some write tests. What the long selftest gives you is the number of the wirst unrecoverable error in the selftest log. You can use that for a selective overwrite. Personally I use Linux and do a dd_rescue -w /dev/zero /dev/<disk> to overwrite a disk. Arno -- Arno Wagner, Dr. sc. techn., Dipl.
