Drive Optimizer:
This program will optimize floppy disks, hard disks, and ram disks
(i.e. RAD). It is designed to provide for the safest optimization
of your disks. It moves one disk block at a time to ensure this.
So it will be slower than other optimizers which usually move
whole tracks at a time. One Meg should take about six minutes to
optimize on a hard disk that uses a Supra WordSync. The program
does multitask, but do not use programs which will access the disk
during the optimization or its crash city.
As with any optimizer make sure that your disk has been
backed up recently in the event that something external happens
such as a power surge or earthquake. If anything does happen, just
use DiskDoctor to repair your disk.
Drive Optimizer is startable from the Workbench or from the CLI.
There are no CLI options.
The biggest thing the user will see is the block field. This will
show which blocks are free (blue), and used (black or white). A
white pixel denotes a block that is part of a continuous set of
blocks. A black pixel denotes a block that is not in sequence.
Below the block field are four statistics: Files and Blocks Left
to move, Percent Done, and Time Done. Before optimizing, the first
two statistics show the total number of files and directories, and
blocks used. During optimization, Time Done shows the expected
time when the program should be done.
Below the statistics are the four control gadgets. There is the
START gadget for starting the optimization. The SCAN gadget for
collecting information about where the files are. The DRIVE gadget
for setting which drive to optimize. Last is the CANCEL gadget for
exiting or for stoping the scan or optimization.
Before you can optimize, you must first scan your disk. The
program will not allow you to start if you don't. If you stop the
optimization, you can restart just by clicking on the START gadget
unless you changed the drive, rescanned, or exited.
After a successful optimization, the free blocks are zeroed to
clean up so that if you use diskdoctor latter on you will not have
problems such as blocks used more than once.
If you have questions or have a bug to report, my handle on PLINK
is Timeus.
This is a freeware program that may be freely distributed. It is
not to be sold, but can be placed on public-domain disks for
distribution.
I take no responsibility for loss of data.
