Sequential R/W Test This test checks the sequential seek, read, and write capabilities of a floppy disk drive. It performs a sequential read/write operation on the diskette in the specified drive. To perform this test, insert a diskette into the drive you plan to test. Use a diskette you have formatted with the Diskette Format test. This test destroys all data on the diskette. Disk Change Line Test This test checks the status of the disk change line. This line should change when you insert or remove a diskette from a floppy disk drive. To perform this test, insert a diskette into the drive you plan to test. Use a diskette you have formatted with the Diskette Format test. Floppy Disk Error Messages The program displays two types of error messages while testing the floppy disk drive: messages the program itself generates and those the controller generates. The program may display the following error messages during the Disk Change Line test: Warning - Change line in-operational This message appears if the line is not working properly. This may indicate a problem exists with the floppy drive or the controller. System Diagnostics D-33
