I've recently bought a H&B CA-5555 stereo for £85 incl postage when I bought it: http://www.pixmania.co.uk/uk/uk/114326/art/h-b/ca-5555-cd-mp3-usb-car-ra.html# It's got a USB port on the front so I bought a 3.5" HD enclosure for £19, a £10 12v regulated car adapter and had an old 20GIG HD lying around. It can read 200 folder of mp3s and a max of 500 mp3s. However I want more. So i'm going to see if the stereo will read a number of 1GIG partions on the HD so I can have 200 folders on each partition. Has anyone got any idea of what specifications (partition/file system) that the stereo would require for this to be possible? Cheers, jon.
