[PLUG] fdisk and SD Multimedia Card on Zaurus

["Jason Wertz" <JWERTZ@dccc.edu>]

I just got a Lexar 64mb Secure Digital Multimedia card for my Zaurus (it is listed as fully compatible). The Zaurus is only recognizing it as having 29mb available for storage. I fired up fdisk and here's what I found .

Disk /dev/mmcda: 8 heads, 32 sectors, 485 cylinders
Units = cylinders of 256 * 512 bytes

Device Boot         Start         End         Blocks       Id         System
/dev/mmcda1         1            485        62079+       5        Extended

I've run fdisk a couple of times with different paramters and filesystems (I'd prefer it to be FAT16) and each time the card remains at 29MB. 

What is interesting, if I multiply heads*sectors*cylinders I'm showing that the card has the potential to store 128MB of data. Am I wrong about that? How should I approach formatting the card to take advantage of that or at least the true 64MB? Do I have a bad card? Beyond the basic features of fdisk I've never done anything complicated with drive geometry.

Thanks.
