Troubleshooting a Non-SCSI Internal Tape Drive In a drive configuration containing both a single diskette drive and an internal tape drive that is not a small computer system interface (SCSI) drive, the diskette drive and the tape drive are connected, respectively, to the drive A and drive B connectors on the diskette/tape drive interface cable. When the internal diskette/tape drive subsystem is configured in this manner, the Drive B category on the System Board Options screen in the EISA Configuration Utility and the Diskette Drive B category in the System Setup program must be set to Not Installed to prevent interference with tape drive operation. NOTE: Some systems may have an external tape drive, in which case a special tape-drive controller card must be installed in one of the expansion slots. The troubleshooting procedure in this subsection applies specifically to internal tape drives. Tape drive problems usually result from a defective tape drive, a defective tape cartridge, or software. Follow these steps to troubleshoot a non-SCSI internal tape drive: 1. Remove the tape that was in use when the problem occurred, and replace it with a tape that you know is not defective. Is the problem resolved? Yes. The original tape was defective. Replace it with a new tape. You have fixed the problem. No. Go to step 2. 2. Remove any installed terminate-and-stayresident (TSR) programs. See "Memory-Resident Programs" in Chapter 3 for information about unloading TSR programs. Is the problem resolved? Yes. The TSR program was conflicting with the tape backup software. You have fixed the problem. No. Go to step 3. 3. Reinstall the tape backup software as instructed in the tape-backup software documentation. Is the problem resolved? Yes. The tape backup software was corrupted. You have fixed the problem. No. Go to step 4. 4. If the system contains a single diskette drive, enter the System Setup program, and verify that the Diskette Drive B category is set to Not Installed. See your system documentation for instructions. Is the Diskette Drive B category set to Not Installed? Yes. Go to step 6. No. Go to step 5. 5. Correct the Diskette Drive B category setting.
