Hi , i am currently working on a project for massive storage device.
what i need now is the way of interfacing an USB external hard disk drive to a 8051 microcontroller. Anyone can provide me datasheet of a HDD (western digital is preferred )? i have experience interfacing 8051 with a secure disk (SD) card .



thank you !

    Every USB disk I've seen uses what is called the "SCSI Transparent Command Set", so you'll need the SCSI specs, not the Western specs. Also, you'll need to go through the USB host controller before you can even see the USB disk -- do you already have a host controller driver?
