Sd Formatting Trouble
« on: January 31, 2008, 03:52:49 am »
Hi there,

When I try to format me new 2gb sd card(mkfs.vfat -F 16 /dev/mmcda1), I get this warning:

WARNING: Not enough clusters for a 16 bit FAT!mThe filesystem will be misinterpreted as having a 12 bit FAT without mount option "fat=16".
mkfs.vfat: attempting to create a too large file system

Is there a maximum partition size that I'm exceeding?

Also, when I try to mount the partiton(mount /dev/mmcda1 /mnt/card), I get:

mount: Mounting /dev/mmcda1 on /mnt/card failed: Invalid argument

By the way, I'm doing this stuff from `Konsole` under Cacko. The card was still read/writable using my card reader connected to my laptop, but when I tried getting the Uboot stuff to work, the lights never stopped flashing. Any advice(besides grow a brain)?

Thanks,

Matt

might need to increase cluster sizes to make it work?
try using fdisk to delete the partition and re-create it as fat16-LBA?

if that fails, try fat32?

Sorry for the dumb question. I'll look a little harder before I post next time.
