Yes, this is a bug I'm working on right now. It doesn't work
depending on the content of the card.

Heh, your card isn't a 256 mega Bytes card. It's 501760 sectors,
which is exactly 245 * 1024 * 2 sectors, hence 245 MB. ATA Support
won't make your cards larger ;)

Well, this isn't very likely to happen. OK. I'll write a FAQ with the
explanation of why.

>PS: The card reads: Scandisk 256MB Compactflash

It's 256901120 bytes, so they say 256 MB, but it doesn't mean 256 *
2^20 bytes, but 256 * 10^6 bytes.
