Fat 12 is a very, very old standard (<dos3.3), you want to format it to fat 16. Fat 12 will only support up to 32mb and I don't think the gp32 supports it.
Wouldn't an allocation unit of 2048 be possible with a 128mb card (2048x65536=134217728)/1024=131072/1024=128meg (computer meg as in 1024x1024, not disk meg 1000x1000 so a 128mb disk is actually smaller in computer numbers).
Just out of curiosity, is there any way to format in fat 12 anymore? If I am not mistaken, dos 3.3 dropped support for fat 12 (as far as formatting). Even a 10 or 20 meg hard disk would be formatted with fat 16.
That's kind of what I was alluding to, since the computer doesn't recognize a mb as a mb. It's been a long time since my data recovery class but I couldn't remember how many allocation units were set aside for the root directory and the file allocation table.
It's hard to figure out who to blame it on. Technically the disk manufacturers are right and the computer is misrepresenting the size. 1 megabyte is 1 million bytes by real math. 1 MB is not 1048576 bytes. OTOH, the drive manufacturers know this and should advertise the size as the computer will report them. But then if 1 manufacturer sticks to the real math, then the rest of them are at a disadvantage as their hard disks will look smaller than the other one.

As for FAT12, floppies are still formatted in it, but nothing else I believe.
