Diskette Format; Drive Speed Test; Random R/W Test - Epson Equity LT-386SX User Manual

Diskette Format

This test checks the format of the floppy disk controller and
drive. It does not format the diskette for any particular
operating system.
This test destroys all data on the diskette.

Drive Speed Test

This test verifies how fast the floppy drive rotates a diskette.
Your internal, 1.44MB, 3 '/ z-inch diskette drive should rotate
the diskette at 300 rpm, allowing a tolerance of one percent.
An external, 1.2MB, 5 '/+-inch diskette drive should rotate a
1.2MB diskette at 360 rpm and a 360KB diskette at 300 rpm.
Again, allow one percent tolerance.
To perform this test, insert a diskette into the drive you plan to
test. Use a diskette you have formatted with the Diskette
Format test.

Random R/W Test

This test checks the random seek capability of a floppy disk
drive. It performs a random read/write operation on the diskette
in the specified drive.
To perform this test, insert a diskette into the drive you plan to
test. Use a diskette you have formatted with the Diskette
Format test.
This test destroys all data on the diskette.
