Errr - that's a damn good idea, actually - SanDisk do an IDE CF drive of varying sizes. It could go onto the disk cable as a secondary/slave.

It wouldn't be much good if the kernel probed it and tried to use it as a second drive to stash music files on though; you'd have to sort out some way of stopping it being mounted at startup and used by the player, but still be able to mount it from some application that could use it. Hmm.

I'mg going to go and have a think about this 'cos I could use a rw mountable partition.
