As I know the disk utilities, they don't use the limit supposed by the
kernel and they just keep trying till the end. When they get this error they
suppose that the disk is at it's end !!

Isuppose when you have doubts about badblocks in a harddisk, the best way is
to Low Level Format it and the LLF Tool will output any badblock !

As I know, testing for badblocks is a raw testing and is not consistent for
just partitions, that's why they have to be ran for the hole disk !

Good Luck
