== The Problem ==
The [[Amstrad_Disk_Drive|Amstrad DDI-1 Disc Interface ]] was made to be used with [[Amstrad_Disk_Drive|Amstrad FD-1 Floppy Drives ]] only. To deter users from using other drives Amstrad implemented two features to make standard PC drives incompatible:
* The 34way cable to the floppy uses a non-standard pinout.
The 3.5" Drive will still need to be connected with a standard 5V / 12V supply as usual and you will need to have modified it to send a ready signal. Additionally, PC drives are usually configured to be Drive B: (DS1), so the drive will also be seen as drive B: by the CPC. However, this can also usually be configured inside the floppy, so that the drive will function as drive A: on the CPC.
