This is a brief 'readme' about Diskopti.lzh. This lharc file
contains two programs, two doc files, and icons for all four. The
information here is an excerpt of the actual doc files. My name
is Jim Pierce and I am on Bitnet and Internet. The easiest way,
and fastest, is to send email to me at JMPIERCE@USMCP5.BITNET. My
email address on Internet is only checked by me once a week so
I'm not posting it here. I didn't write these programs, the
author's name and address is in the doc files and at the end of
this file. Several people on I-AMIGA asked me to post this here.
I-AMIGA@UTARLVM1.BITNET is where I usually hang out.

DiskOpti
The purpose of this program is to copy an entire disk in a way
which will allow the files to be read faster by rearranging the data
blocks. This program will copy all the files on a disk making sure
that the data blocks for each file are consecutive. Depending on the
number of directories and files on a disk, the process can take up
to 6 minutes to complete.
Usage of the program is straight forward, place the disk to be
optimized in one disk drive and a formatted disk in another drive,
then select the appropriate menu selection, for example df0: ->
df1:, this means the source disk is df0: and the destination disk is
in df1:. Then wait until the process is complete.
This program works either from the Workbench or the CLI. It is
entirely written in assembler for faster operation and smaller size.
You can also use the included DiskView program to look at the
position of the file and directory blocks on the disk.
Conclusion: I still have to work on the program to make the Dir
command faster while keeping the other timings the same. For the
rest I will let you make your own conclusions.

DiskView.
This program dispalys a map of the blocks allocated for the
files and directories on a disk. It consists of a grid showing all
the 1760 blocks of a disk. The x axis represents the 80 cylinders
( 160 tracks ) numbered from 0 to 79, the y axis lists the 11 blocks
from 0 to 10 for each side for a total of 22 blocks per cylinder.
Blocks 0 and 1 are reserved for the boot block or a virus...!
Block 880 (cylinder 40, block 0) is for the root directory.
This program is written in assembler, it works from either the CLI
or Workbench.
Comments, questions or suggestions are welcome.
