||Year of production:
Diskey is a comprehensive collection of routines neatly tied together to allow you to unlock your drive for diagnostic, recovery or whatever reasons you may have. Many of the functions are available on other disk utility packages or through users' groups libraries of public domain software, but a few of the key routines are unique to Diskey (Erase Disk without reformatting and Special File Copy without any directory entry, for example.) Diskey is written in BASIC with many Assembly routines which give it an edge over some other utilities as far as speed goes.
