Im new here, and wanting to know if its possible to make a Hard drive be interface as an EEPROM.
And if someone can show me a site on how the address and data lines work on IDE hard drives.(I already have a knowledge of EEPROMS dont worry about that) 
Well anyone have any ideas? Its just a simple thing of translating the address line of the hard drive, can anyone tell me how?
I think you will find that that you will need some type of microcontroller and software that sits between the IDE connector and the EEPROM. "Addresses" on a disk interface are more like high-level commands -- something needs to read the command, and convert it into the low-level hardware actions that send a block of data over. You will also need a buffer because when the system sends data to your device, it will probably send a chunk at a time and send it faster than you can write it out to EEPROM. I sure it can be done, people used to sell silicon SCSI drives.
I'll bet making silicon pretend to be a hard drive is a hell of a lot easier than the other way round.
Well Thanks anyway Ill read up some more and if I find anything good Ill post it.
