Select 1 (for drive A) or 2 (for drive B). If any errors occur,

center.
When you finish testing the device and return to the menu,

Sequential Seek Check
This test checks the ability of the read/write heads to locate any
part of the diskette. This action by a read/write head is called a
seek. During this test, each head seeks sequentially from the
innermost track to the outermost track. The innermost track is
track 79 for 1.44MB, 1.2MB, and 720KB diskettes and track 39
for 360KB diskettes.
