- 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.
