 TOPIC ------------------------------------------------------------

 In what Apple floppy disk drives can I use high-density diskettes?

 DISCUSSION -------------------------------------------------------

 High-density diskettes (1.44MB only) are suitable for use in Apple SuperDrive
 (formerly Apple FDHD).

 High-density diskettes are NOT suitable for use with:
 - Macintosh 400K drives
 - Macintosh 800K drives
 - Apple II 3.5-inch drives

 High-density diskettes are physically different from double-density diskettes
 and are tested to a different specification. The coating on a high-density
 diskette is thinner for higher data-packing density.  Use in 400K or 800K
 drives is unreliable and can cause data loss.
