sector number equals fspare or fbad.
HRM
Sector numbers can be interleaved. The default format
does not interleave sectors (physical sector# N on a
track is also logical sector# N). By setting fstart
(starting logical sector number) and fintvl (logical
sector number difference between physically contiguous
sectors) appropriately, sectors can be interleaved.
EXAMPLE:
SFMT 33 32 ffffH 0 3
FMT 33 2 3 0
The first line sets up the format parameters: fmtsec =
33 sectors/track, fspare = 32, fbad = ffffH, fstart =
0, fintvl = 3. The second line formats 33 sectors on
the track at cylinder 2, head 3. The sectors are
interleaved (0, 3, 6, 9 and so on) and the last logical
sector (sector# 32) is flagged as a spare sector. No
sectors are flagged as bad.
COMMAND: FVOL
DESCRIPTION:
Formats the entire vo~ume, track by track. The format
parameters of the SFMT command determine how the disk
is formatted.
EXAMPLE:
SFMT 33 32 FFFFH 0 1
FVOL
The first line sets up the format specificatio~s for an
80 Megabyte drive with 33 total sectors per track. The
last sector (sector 32) is designated as a spare. No
sectors are designated as bad. Logical sector numbers
start with 0, and the interleave factor is 1 (there is
no interleaving of sectors).
The second line formats the current disk unit track by
track using the format parameters defined in the SFMT
command.
