Key-Disk Copy Protection Doesn’t Work with Disk Plus PSS ID Number: Q49672 Article last modified on 11-22-1994 PSS database name: HARDWARE

1.00 MS-DOS

Software that uses the “key disk” method of copy protection does not work on a computer that has the MACH 20 Disk Plus installed. The method that the Disk Plus uses to access the data on the disk drive is slightly different from that of the standard IBM floppy-disk controller, and thus interferes with the error checking used in the “key disk” copy protection scheme. To correct this problem, contact the manufacturer of the piece of software and ask to obtain either a version of the application that is not copy-protected or a version that uses a different method of copy protection.
