How do I make rsync ignore unreadable files (damaged sectors)?

Your suggestion, to make the destination volume (USB stick) full, will
result in write errors! If you mean "size-limit" by "overwrite-limit"
What we wanted was, how to provoke read errors, and Paul Slootman
already offered a solution for that: hdparm --make-bad-sector.
Or did you mean to write a small testfile on a flash drive, then
overwrite it multiple times (more often than the specified "overwrite
limit") by an automated loop, as long until you get the first write
error, and hence you can expect a bad sector at this file, and then
use it as a broken test source?
Now some German talk: Servas Oida! Gruesse aus Wean (Wien) ;-) Stefan
