Compact Flash memory test

[Mike Bushroe]

We maintaining an embedded Linux device performing the routing
functions in an Etherswitch. Up till now, we have sent the boards or
entire boxes back to the vendor (G.E.) for any firmware or hardware
repair. We are now rethinking this, since the most common hardware
failure is the power supply, and they use generic, open frame PC
switching power supplies, and defective firmware, which is stored on a
64Mb Compact Flash card. We have now removed one of the flash cards
and tarballed the contents and we want to transfer it onto a fresh,
never been to GE flash card, plug it in and see if everything works
right. So I just bought a lot of 10 128Mb Compact Flash cards that
were sold 'As Is". I want to know if anyone knows of a memory tester
for Compact Flash cards that are being used as the main file system
for a small Linux box. The Flash Card is formatted ext3, but we can
probably test them first, then format them for Linux and install the
system from the tarball. It would be helpful if the file system test
could be run under Ubuntu or Windows XP.

Anybody have any suggestions? Does the built in fsck do enough of a
check to find bad cells in a Compact Flash card/drive?
