Does anyone know the maximum size for a fully-functional FAT32 drive? I had a link sometime that said, but seem to have lost it...

Basically, I'd be using this drive under Linux/Windows, and can create it with a tool from either. Ditto for maintenance.

Depends on what you use. This  page has quite a few limits on it although it is a bit old.

It's about 2TB. The Windows utility won't be able to format anything over 32GB, but a third party one should work. If you have a retail drive then those usually come with a format utilities that work well.

Thanks. :) I thought there was something regarding data corruption on volumes larger than a certain size though...is there a reliable source that debunks that?

I had problems at about 100GB during my WXP/Ubuntu experiment. Write errors and the like.

That's FAT16.

The maximum size varies directly with the block size that you specify (as does pretty much every other limitation of FAT32), at least so far as I recall.  There's other limitations when Scandisk gets involved though.
