When I put in new 2GB card, I partitioned it using following commands

# sfdisk /dev/mmcblk0
/dev/mmcblk0p1:1,52500,6
/dev/mmcblk0p2:52501,,
/dev/mmcblk0p3:
/dev/mmcblk0p4:

So in effect mmcblk0p1 is mmc1 and is about 1.6 GB. I put the dual boot os in mmcblk0p2 with excellent help from Fanoush and with his tool/utils/scripts.

Now MMC1 is 1.6 GB but is FAT 16 and hence block size of 32 KB. I when I copied about 15000 gifs (individual frames of video), with each frame being gif and small file i.e. < 1 KB. These 15000 files should be taking about 15 MB, but is taking about 480 MB, due to block size of FAT 16 on MMC1 which I believe is due to 32 KB.

Is there a way I can change this mmc1 parition to FAT32 ? Or partition it into two one for FAT16 (if required) and another for FAT32 ? And that too without disturbing, /dev/mmcblk0p2 so that I do not have re-do the clone OS thingy. I installed a few applications after doing the clone.

I searched the forums, there is lot of talk about having more than 2 partition and also how to make FAT32 parition. But couldn't find any thing which say how to delete just one partition or re-do FAT16 parition to FAT32 partition without disturbing dual OS.

Thank in advance.
