the Personal Computer AT High Capacity Diskette Drive, reformat
the diskette before using it in a Personal Computer AT Dual-Sided

a dual-sided diskette can only be read by a Personal Computer AT
High Capacity Diskette Drive. To guard against accidental writing on
these diskettes, you can place a write-protect tab on the diskette
before you use it. Refer to "Write-Protect" on page 1-14.
