WINCHESTER DRIVE TEST
WINCHESTER SUBSYSTEM
The Winchester subsystem is made up of three main units, those being the
Winchester controller card, which resides in the 5-100 bus, the interface card,
which plugs onto the back of the drive, and the drive itself.
The power is
supplied by a DC cable and by an AC cable for the 8" drives.
The data is
tr ansf erred by a ribbon cable that connects between the controller card and the
interface card.
I
The data is held on the drive in 512 byte sectors.
There are a number of sectors
per track.
The track specifies a head and a cylinder location.
The drives can
have as many as eight heads and 512 cylinders.
This would give a total of 4096
tracks.
The error message given by the operating system defines the bad location
in terms of a track and a sector location.
Start the Winchester test by typing TSTW <cr>.
The system will respond with
the f allowing message:
