Zero HDD Attempt to Fix Bad Sector

Featured Replies

Hello,

 

What's the easiest way to zero a HDD in Unraid.     I am hoping to repair a bad sector.

Use the Preclear plugin.

Will this actually relocate a bad sector in the "do not use" part of the HDD's firmware?  If not, is there anything i could run in unraid to do this with?  lets assume i don't care about the data on the HDD's.  Over the years, i have gotten given many HDD's from clients, some work well, some not so much, but i would like to set up something to run all HDD's through a check/repair process (and trash the ones that fail at the HW level).
