On the Macintosh life is slightly complicated by Apple's

decision to include device drivers on mass storage drives

themselves — therefore a mass-storage device that is

connected by SCSI will have different preliminary data on it
|
|
than the same volume connected by ATA or as an HD20.
|

|
|
Mass storage devices that respond to @c Volume can be made
|

to provide the proper whole-volume encoding necessary to
|

impersonate different types of Macintosh drive.
