> "... and cache the entire tree in RAM". My FAT32 lib requires you to read the entire current directory into ram. For me, this is a requirement for a mp3 player, it allows random play. I suggest you make directories for each type of music, similar to what I believe IPOD does.

I have not found any 40 pin PIC's that can use SPI + HDD + USB due to pinouts. There is currently no spi software lib, but it shouldn't be hard to make. However, SPI hardware is better/faster. I guess you could just give SPI software it a try and see if it runs fast enough for you. Other suggestions, Have you thought about also connecting a SD card slot? For transferring data, I think there is a way to use a real hard disk to USB adapter inline with your circuit.
