Hacking Format 4gb to FAT32 with 64k clusters?

[tomgibbes]

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?

You can't use 64k clusters with FAT32, only regular FAT.

We have this SD formatter. Might work:

Still, your SD card would be ok for most games if not all...
In case you do encounter some issues, Micro SD cards a cheap now. I suggest you grab a 512MB or 1GB Kingston just for that special game.

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.

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.
