HP45811A 360KB Internal Flexible
Disc Drive
The 360KB Internal Flexible Disc Drive can be purchased as an
accessory to the HP Vedra (product number HP45811A). It is used
to store formatted data on double-sided 5/14 inch flexible discs. It
is easily identified by the asterisk molded into the faceplate just
below
the activity light. The flexible disc controller subsystem can
support
up to two flexible disc drives, either or both may be the
360KB internal flexible disc drive.
The drive can read and
write on Double-Sided Mini-Discs
(HP92190A
or equivalent). Also, it can read and write to single-
sided discs, however, excessive head wear results when single-
sided discs are used. It
is recommended that data from single-
sided
discs be copied to double-sided discs, then only the double-
sided
discs be used with the 360KB Internal Flexible Disc Drive.
The 360KB Internal Flexible
Disc Drive chassis is 171 mm wide x
41 mm high x 207mm deep. It weighs 1.6kg and fits in either of
the half-height disc drive cages. It draws a maximum of 19.8
watts from
the power supply. Table 9.1 describes the
performance
of the 360KB Internal Flexible Disc Drive when
properly installed in the HP Vedra PC.
