My hard disks support some programmable options. Automatic Write Reallocation Enable (AWRE): On, drive automatically relocates bad blocks detected during write operations. Off, drive creates Check Condition status with sense key of Medium Error if bad blocks are detected during write operations. Automatic Read Reallocation Enable (ARRE): On, drive automatically relocates bad blocks detected during read operations. Off, drive creates Check Condition status with sense key of Medium Error if bad blocks are detected during read operations. These options are both off. Would md be happier if these were on? This would hide recoverable errors from md. Any opinions? My disks are ST118202LC.
