Well, for the kinds of use to which we'd put the device (ie: streaming tape) a 32k block size isn't horrid. I can see where if you tried to use it as a random-access replacement (ie: to write "files" to) you'd be rather unhappy with the wastage that this would cause, but for streaming applications I doubt it hurts much. I'll try hardcoding THAT as a quirk and see if the drive decides it would like to at least get past the open and actually perform I/O :-) -- -- Karl Denninger (karl@denninger.net) Web: fathers.denninger.net I ain't even *authorized* to speak for anyone other than myself, so give up now on trying to associate my words with any particular organization.
