Hi Richard,

Do some searching, you will find it. Google is your friend! There are also links to Fat16/32 documentation here...have you searched this site?

Remember that there is a LOT of open source code out there, and even though it may be for a non-8051 environment. Linux has Fat16/32 support, and I know of at least one AVR Fat16/32 implementation (along with the IDE/ATA interface).

You should be able to port something to your chip, if you are unable to find something specifically for the 8051.
