Viewing the Bad Blocks on a Drive
During a rebuild, the bad block table receives entries from a rebuild with errors. If
you are using the Rebuild option to rebuild a disk and the rebuild fails, the drive
remains in the WOL (write only) state. You can use the Bad Block Table option to
view the bad blocks.
