* 1.44MB 3.5" PC MS-DOS formatted discs
The Amstrad 's disc controller can only read Double density discs.AMSDOS is limited to it's own disc formats so it can't read PC formatted discs, the filesystems are not compatible.If you want to read PC double density disc formats use DOSCopy on the Amstrad. 3.5" high density Floppy discs have an extra hole. The drive detects the hole and automatically switches to high density recording mode. It is advised that you either cover the holes with some opaque tape, or you use true double density discs. 5.25" high density floppy discs are the same as 5.25" double density discs, e.g. there is no physical difference except for the surface of the disc itself.
The density of the media determines the total capacity of the drive.
