How do you do that?
man badblocks
badblocks -v -w -s /dev/devicepartition
though, with ext3 I would almost suggest go ahead and format (using the
read-write badblocks test in the format, see below) and then look at the count
using
'dumpe2fs -b /dev/devicepartition'
of course, look at the man page first.

It might come to that :-)

For this one I'd rather have an ext3 partition, if I can't recover it.
then I suggest more along the lines of:
mke2fs -v -c -c -j -L AnneWilsonPendrive /dev/devicepartition
'-c -c' -- Check the device for bad blocks before creating the file system.
using a slower, read-write test instead of a fast read-only test.
