Disk drive type

DIAG displays the following prompt for the disk drive type:

D i s k D r i v e t y p e

? 2

Select drive type 2 for a 20MB drive or drive type 17 for a 40MB drive. DIAG determines the type of hard disk drive based on the settings in CMOS RAM.

A pop-up window on the screen lists 47 possible drive types. This allows for the possibility of additional hard disk drives in the future. If you select the User Defined hard disk drive, you must provide the following information:

Number of cylinders

Number of heads

Number of sectors per track

Write precom

Write precom cylinder number

Landing zone

Interleave factor

DIAG displays the following prompt for the interleave factor:

I n t e r l e a v e ( 1 - 1 6 )

?

The interleave factor affects the performance of your hard disk. The default value is 3.

When you execute the Auto Interleave test, DIAG determines the best interleave value for your hard disk and formats the hard disk for this interleave factor.

If you enter an interleave value in response to the Interleave prompt, you override the value set by DIAG. Only do this if the documentation with your hard disk recommends a different value.
