Yes. The controller ALWAYS maps out bad blocks > whenever they're found, during any type of read or write operation.
If I may summarize the discussion about bad sectors. Bad sectors (blocks) get mapped out on the fly during normal read/ write operations. Bad sectors (blocks) get mapped out within a volume/partition when you zero the volume/partition in Disk Utility or some other tool. Bad sectors (blocks) get mapped out on the hard drive when you zero the entire hard drive in Disk Utility or some other tool. Secure Erase (also Secure Empty Trash) zeros whatever sectors had been previously written to and therefore maps out any bad sectors previously written to, and only those. Zeroing does not equal mapping out. Check?
