The CRC/FORMAT check returns any errors in the form:
cylinder number, head number, sector number, track number
You
can calculate the physical location from the head and cylin-
der number. The formulas are
as
follows:
For 5 megabyte drives:
(track number)
= «cylinder number) x
4)
+ (head number)
For
10 megabyte drives:
(track number)
= «cylinder number) x
3)
+ (head number)
For
20 megabyte drives:
(track number)
= «cylinder number) x
5)
+ (head number)
These
calculations have already been made for you in the track
# column.
Write down
se
track numbers on a piece
of
paper and cancel
out
any duplicates in the list.
Now select the DRIVE PARAMETERS option,
#7,
of
the diag-
nostic program
(CDIAGNOS). Once the drive number is specified
(usually
#1),
the program will list the spared track table, the sector
interleaving spec., and the virtual drive offset table.
