Isn't byte 0 the `35' for the command? I. e., it is complaining that it doesn't understand the SYNCHRONIZE CACHE cmd at all. > This looks like a perfectly valid response. The response might be valid, but the request isn't (for that device). ;-) Not that i'd care much about this drive (it's experimental only, and i know they are crap), but message like this one IMHO confuse the users. SYNCHRONIZE CACHE is marked optional in the standard, i thought we'd automatically detect the non-support of this command by a target, and silently ignore it? -- cheers, J"org .-.-. --... ...-- -.. .
