- Aditional information about OPTIM.COM ...
-
- This program is an attempt to optimise the performance of third party
- fixed disks which are added to IBM clones. It is fully tested on I.B.M.
- Amstrad PC1512 and Olivetti. IT IS NOT GUARANTEED TO WORK ON OTHER MACHINES
- (yet!).
-
- The program completes a test format of cylinders 0 and 1 at each interleave
- setting. Then 8 passes are made to average out the time taken to access
- these cylinders. Once the lowest access time has been found, the
- whole disk is formatted to that interleave setting.
- THIS IS A LOW LEVEL FORMAT - IT REWRITES SECTOR ID'S AND SUCH.
- DATA CAN NOT BE RECOVERED AFTER SUCH A FORMAT PROCESS.

- ***** WARNING *****
- I recently ran this program inadvertently on a Compaq 386 machine which
- as any clod knows, has a 16 bit disk controller access system.
- I SCREWED UP THE DISK. Track zero was completely inaccessible and the
- machine was incapable of recognising the disk. I could only rescue it
- when a good friend let me have a copy of the Compaq Diagnostics Disk
- which has a low level format program on it. (Phew!)
- PLEASE PLEASE PLEASE learn from this. Don't try OPTIM unless you have
- some other way of reformatting your hard disk if things should go wrong.
-
- Now that I've got that off my chest, OPTIM really works extremely well
- in matching particular disks with specific processors. A colleague of
- mine and I both bought Seagate ST225 20Mbyte fixed disks for our
- respective machines. Same controllers and everything. His machine
- was an Olivetti M24 and mine is an I.B.M. XT. After installation, my
- disk was timed at better than three times faster than the Olivetti!!!
- This started us thinking and tinkering, and OPTIM was the result.
- Now that we've run OPTIM on both machines, his is slightly faster than
- mine and both are faster than mine was before OPTIM. Even though the
- Disk hardware is identical, the optimum setting on the Olivetti is
- different to the one on the I.B.M. and neither is the same as the
- manufacturers recommendation! So - if you can use, do so - and your
- computing should be better and faster for it. I'm still developing this
- so please let me know what results you get. You can reach me on :-
