FLOPPY DRIVB
TEST :
Each
floppy drive ls tested
accordlng
to
the
parameters
defined
for lt
ln the BI0S.
These
parameters
are
read durlng startup.
In
thls
way
the
test can be
set
for
different
types
of drlves
and
formats wlth only
nLnor changes.
The scratch
dlskettes
used
for
the test must
be
formatted to
match
the BI0S setup.
Drlve
lt4
or
ll5
can
be tested
separately
by
uslng ALTER
to shut
off
the
other tests.
DRIVE
FORMAT:
80
or
40
cylinders
per
di-skette.
2
heads
(tracks)
per
cylinder, one
on each
side
8
sectors/track
(head)
5L2
bytes/sector
5I2
bytes/block:
sectors
size
=
block sl-ze.
1280
blocks
per
80
"track"
dlskette.
640
blocks
per
40
"track"
diskette.
4096 bytes
in one
head of one cyllnder.
Because there
are really two tracks
to each cyllnder,
the diskettes
would be more
properly
called
80
"cylinder"
and
40
""ylinder"
drlves
but
the older, single-slded
nomenclature
has
carrled
over
here.
The dlsk test
does
the
following
operatlons:
The entire dlskette
ls
wrltten cyllnder
by cyllnder
(4096
bytes
)
wlth
a
code
at
the
front
of each
cyllnder and checked
for hard
and
soft errors on the
write.
Ttre
diskette
ls read
cyllnder
by cyllnder
and
checked
for
hard and
soft errors on the read.
If
a
hard
error occurred
the
cyllnder
ls
not
read.
NUM
SCRIPT The
data compared
wlth the written data. If
elther a hard error or
a
soft
error occurred
this
ls not
done.
Errors
are logged
and a
maJor
error
will
termlnate the test on that
drlve.
Testlng of
the
oEher drive continues.
The test
falls
lf a
drive exceeds
the
fallure
parameters
set
ln the
parameter
fi.le
CYC.PARAIT{. They can be changed
by the ALTER
optlon
but
SHOULD
NOT BE
CHANGED unless specified by SAGE.
At the end
of
the
test or when an ESC
ls typed, the errors are
added
up
so
that the
graphs
and
displays can be
shown.
