On CF, IOCS16- is honored--but it's not on any IDE
hard drive
you're going to buy today.
So, is there anything stopping someone from using a MicroDrive? It
should be more than fast enough.
Don't think so, except mechanical issues where a CF card has
advantages. The Microdrive is CF+ standard which needs to implement
the Common Memory transfer (8 and 16 bit). It is just the "True IDE
mode which is optional within the spec, although I am sure the
Microdrive will understand it.
The reason I thought of Microdrive over regular CF is the canonical
reason why people suggest Microdrives: greater write cycle lifetime.
