Press Y and Enter to start analyzing the hard disk. Press N and Enter to stop the operation. Performance Test This test checks the performance of your hard disk. It determines the data transfer rate and track-to-track seek time based on the transfer size, seek count, and the amount of data transferred. The interleave factor is the most critical factor in determining disk performance. Changing the interleave factor can drastically change disk performance. The program measures the data transfer rate in kilobytes per second. To measure the data transfer rate, the program reads 64KB of data 15 times and counts the number of timer ticks using this formula: Transfer rate = (64KB x 15 x 18.2) /# timer ticks The program measures track-to-track seek time in milliseconds using this formula: Seek time = (#timer ticks x 1000) / 18.2 x 200 The number of seeks is 200. A higher data transfer rate and a lower seek time indicate better disk performance. System Diagnostics D-27

The program displays the following messages after you specify
the hard disk parameters:
WARNING
All data on Hard disk you have
specified may be LOST...
Do you still want to continue (Y/N)?
Press
Y
and
Enter
to start analyzing the hard disk. Press
N
and
Enter
to stop the operation.
Performance Test
This test checks the performance of your hard disk. It
determines the data transfer rate and track-to-track seek time
based on the transfer size, seek count, and the amount of data
transferred.
The interleave factor is the most critical factor in determining
disk performance. Changing the interleave factor can drastically
change disk performance.
The program measures the data transfer rate in kilobytes per
second. To measure the data transfer rate, the program reads
64KB of data 15 times and counts the number of timer ticks
using this formula:
Transfer rate = (64KB x 15 x 18.2) /# timer ticks
The program measures track-to-track seek time in milliseconds
using this formula:
Seek time = (#timer ticks x 1000) / 18.2 x 200
The number of seeks is 200.
A higher data transfer rate and a lower seek time indicate better
disk performance.
