Sector Corrector
------ ---------

I have recorded two programs, Sector
Corrector and Dynamic Renewing.
The first program checks out
all unused sectors on a disk and
allocates any bad blocks. If bad
blocks are found, the operator is
instructed to load the program Dynamic
Renewing. The cassette buffer is used
to pass track and sector information
to the second program. This program
uses the dynamic keyboard technique to
modify itself. When the disk is full
or inefficient, load and run the
program "RENEW THIS DISK". "RENEW" is
the modified version of "dynamic re-
newing". This program will new the
disk and immediately allocate the bad
sectors. Then it will save itself to
the disk. Practice using these two
programs on a scratch disk before
using them on a disk with programs.
Lots of information and warnings are
built into the program.
A program on the test/demo disk
that is provided with all 1541 drives,
CHECK DISK, requires about 45 min to
check out a disk due to a program
flaw. Sector corrector will test a
blank disk in 8 minutes. Disks with
files take less time; disks with a lot
of bad blocks take more time.
