Subject: compactflash cards dying in < hour?

Hi!

I had three diferent CF cards, from two different manufacturers
(Apacer and Transcend), and both died *really fast*.

Last one (transcend) died in less than 10 minutes: mke2fs, cat
/dev/urandom > foo; md5sum foo (few times); cat /dev/urandom > foo and
I could no longer do cat /dev/urandom because of disk errors.

I know CompactFlash cards are *crap*, but they should not be *so*
crappy...?! [I'm testing them from toshiba satellite 4030cdt via
Apacer PCMCIA-to-CF adapter and in sharp zaurus].

Are there "known good" 256MB compact flash cards?

We have some SanDisk CF's here which have withstood at least 20 cycles
of fdisk, mke3fs, and installation of a mini-linux distribution. They
are all still running ok. (64 MB mostly, some 128 MB)

They have been accessed through SanDisk USB-to-CF adapters, and also
directly to the IDE channel of Geode-based embedded systems.
