OK. The smallest card I have is 2GB, and I really don't want to lose its
content for a test. Aside from that, I only have 8GB and 16GB...

Now I'm confused. I thought you said this problem happened when there
was a raw filesystem placed directly onto the card, without any kind of
partition table? If so, then I don't see how creating a small partition
on my card would help reproduce the problem.

Again, can you simply send me a compressed image that demonstrates this
problem. Something like:

(WARNING: this will wipe any data on your SD card)

dd if=/dev/zero of=/dev/whatever-your-sd-card-is bs=32768

Then, format/... the card in Windows

Then, validate that the problem reproduces with it

(or just skip all the above if your current SD card content isn't
confidential, and there's little enough data that it will compress well)

dd if=/dev/whatever-your-sd-card-is of=sd.img bs=32768
bzip2 sd.img

Then, mail me sd.img.bz2

Thanks.
