I want the best performance from my slow Sandisk 4gb micro sd. I have tried to format it to FAT32 with 64k clusters in windows but i get a error saying the file unit size is to big for the file system. Is there any other way of doing it with another program or something?

I will try the formatter in a few mins, when i tried formatting to FAT in windows it just formats it to FAT32. Is there some limitation that stops it formatting to just FAT if it is a certain size?

EDIT: Cannot see where to select cluster size in the formatter?

FAT is limited to 2G under windows implementations.
wikipedia said:
With the usual hard disk sector size of 512 bytes, this gives 32 KB clusters, thereby fixing the "definitive" limit for the FAT16 partition size at 2 gibibytes.
Indeed, there was even a time where PC bios' didn't support disks larger than a few gigs because of the FAT limitations.
