Title: Formatting 2GB SD with FAT32 and 32K cluster size for Minimig
Post by: gaula92 on December 02, 2010, 08:18:18 PM
Is it possible to format a 2GB SD card to 32K cluster size? I DID format a 4GB one, but I'm getting an error when trying to format a 2GB one to 32KB cluster size.
The command I'm using in a windows machine is:

format /FS:FAT32 /A:32K

but it says cluster size is too big for FAT32. Is 32K cluster size reserved for bigger partitions?

thanks

PD: Of course I'm trying to format the card for the Minimig

I get the same results, and the drop-down box in the Explorer format dialog does give different allocation sizes for a 2GB vs a 4GB card.

It will work with /FS:FAT if that's any use? I dunno what the requirements are for Minimig. Also I'm not sure if this is a literal spec thing or more down to Microsoft's generally conservative filesystem limits. For instance FAT32 partition sizes are artificially limited to ~32GB but some third-party apps will format them up to the real maximum.

-Edit-

Tried another util that *will* do FAT32 up to 2TB, but still won't get round the clusters issue so I'm guessing it is a hard limit.
