Using Your CD-ROM Drive Mounting and Unmounting a CD-ROM Disc Unmounting a CD-ROM Disc Using SAM Use the following procedure to unmount a CD-ROM disc: NOTICE: Before you unmount a CD-ROM disc, make sure that your working directory (the directory in which a relative path name search begins) is set to some directory other than the one under which the disc was mounted. CAUTION: If you wish to use a CD-ROM disc as a mounted file system, you must mount the CD-ROM disc every time you load it into the drive. You must also unmount the CD-ROM disc every time you unload it from the drive. Failure to mount or unmount a disc may cause a system error condition that may require rebooting the system. 1 Log in as root. If you need information on logging in or setting up a user account, see Using Your HP Workstation. 2 In a terminal window, enter the following command: sam RETURN 3 The System Administration Manager window opens. Double-click on Peripheral Devices ->. 4 The Peripheral Devices window opens. Double-click on Disks and File Systems ->. 5 The Disks and File Systems window opens. Double-click on CD-ROM, Floppy, and Hard Disks. The following screen message appears: Scanning the system’s hardware... The CD-ROM, Floppy, and Hard Disks window opens containing a list of drives currently configured on this system. 6 Highlight the disc you want to unmount and click on Remove a Hard Disk Drive from the Actions menu. 38 Using Your CD-ROM Drive Mounting and Unmounting a CD-ROM Disc 7 A window with the following message opens: Do you want to remove the disk? Click on Yes. 8 Press the eject button on the CD-ROM drive and remove the CD-ROM disc from the disc tray. Reading the Busy Light The CD-ROM busy light shows the status of the drive during the self test and during activity with the host system. The CD-ROM drive performs the self test when one of the following happens: • You load a disc and close the Disc Tray. • You turn on the workstation with a disc already loaded in the CD-ROM drive. For the self test, the busy light operates in the following sequence: 1 Light On - The busy light goes on when the disc loads into the drive. 2 Light Flashing - The light flashes six times while a read test is performed on the disc. 3 Light Off - The light goes off when the self test is complete. Using Your CD-ROM Drive Mounting and Unmounting a CD-ROM Disc The busy light stays on after the self test when one of the following conditions exist: • A defective disc • A disc insertion error (for example, an upside-down disc) • No disc present The busy light goes off when one of the following conditions exist: • A CD-ROM drive power failure exists. • The drive is idle on the SCSI bus. The busy light flashes during normal activity with the system. Using Your CD-ROM Drive Troubleshooting Troubleshooting If you have trouble with any of these procedures for using your CD-ROM drive, see Chapter 5 of this book, “Solving Problems.” Using Your CD-ROM Drive Troubleshooting 42 Using Your Digital Data Storage (DDS) Tape Drive Using Your Digital Data Storage (DDS) Tape Drive This chapter describes how to use the optional Digital Data Storage (DDS) tape drive. It also describes how to maintain and care for the drive. This chapter provides information on the following: • DDS tape drive and data cassette descriptions • Operating the DDS tape drive • Ordering information CAUTION: Use only data cassettes labeled DDS (Digital Data Storage). Never use audio cassettes labeled DAT (Digital Audio Tape) in your DDS-format drive. 44 Using Your Digital Data Storage (DDS) Tape Drive DDS Tape Drive and Data Cassette Descriptions DDS Tape Drive and Data Cassette Descriptions This section describes basic information needed for using your DDS tape drive and data cassettes. DDS Drive Your DDS tape drive is either a DDS-DC (early or later model) or a DDS-2 tape drive with a 3.5-inch form factor, data compression, and a narrow single- ended SCSI interface. Both drives incorporate data compression capability and are high-capacity, high transfer-rate devices for data storage on tape. With compression, the DDS-DC drives can store up to 4 GB of data on a 90 meter tape and the DDS-2 drive can store up to 8 GB of data on a 120 meter tape. Storage Capacities The maximum storage capacities of different DDS drives with and without data compression are shown in the following tables; Table 7 DDS Tape Drive Capacities Without Data Compression Tape Length Full Height 5 1/4 DDS Tape Drive DDS-DC Tape Drives DDS-2 Tape Drive 60 meter 1.3 GB 1.3 GB 1.3 GB 90 meter Not Supported 2.0 GB 2.0 GB 120 meter Not Supported Not Supported 4.0 GB Table 8 DDS Tape Drive Capacities With Data Compression Tape Length Full Height 5 1/4 DDS Tape Drive DDS-DC Tape Drive...
