The program instructs you to place a blank diskette into each drive. The Per-
formance Test Program executes a shortened version of the test used by Commo-
dore in final inspection of the 4040 or 8050. The purpose of this test is to ensure

formance Test Program will re-format them and any data will be lost. The test
program will label these diskettes "Test Disk 1" and "Test Disk 2". These disk-
ettes are ready for further use when the test program is completed and the per-
formance test has been satisfied.
