    Alex,

    I was looking at an eBay listing a while back that was titled "DIGITAL
    DEC TLZ06-AA 8GB EXTERNAL TAPE DRIVE", this description is incorrect based
    upon description?

    I would say the description the posted is incorrect. One could 'market' the
    aforementioned device as 4GB (albeit compressed) or 2GB (uncompressed), the
    bolder marketer may simply say 4GB. I believe however, that marketing a
    TLZ06-AA as 8GB would be incorrect.

    However for any legal matters, or definitive statements on the matter, I
    would recommend you undertake your own independent research.

    TLZ06 Cassette Tape Drive Product

    Description

    1.1 OverviewThe TLZ06 cassette tape drive provides you with high capacity, off-line data
    storage. Depending on the 4 mm data cassette tape used, the unit can
    typicallystore:

    Tape Type (see NOTE 1.) No Compression CompressionTLZ04-CA (60 m) 1.3 GB 2.6 GB

    TLZ06-CA (90 m) 2.0 GB 4.0 GB (see NOTE 2.)


    ------------------------------------------------------------

    NOTE
    ------------------------------------------------------------


    1. The TLZ06 is compatible with TLZ04 (60 m) cassette tapes in thenoncompressed
    mode only.2. The 4.0 GB measurement is typical for a 2-to-1 data compression
    ratio, but the actual ratio is dependent on the data.------------------------------------------------------------


    The maximum time to backup (read or write) on a TLZ06 cassette tape in acontinual
    (streaming) mode is system dependent. The efficient use of streamingmode
    is determined by your operating system. Please refer to your systemsoftware
    documentation.

    TLZ06 Cassette Tape Drive Product Description 1-1



    1.1.1 System SupportAs of this printing, the TLZ06 drive is supported by VAXstation systems and
    DECstation systems. Your particular system must have a standard SCSI(small
    computer system interconnect) port, or a KZQSA (Q-bus to SCSIadapter).

    VAXstation systems can use the VMS or ULTRIX operating systems.DECstation
    systems use the ULTRIX operating system. Consult with yourDigital
    sales support person for operating systems supporting this device.

    1.2 Design FeaturesThe TLZ06 cassette tape drive uses state of the art technology. The TLZ06
    cassette tape drive's design incorporates both digital data storage (DDS)
    anddigital
    audio tape (DAT) recording technologies.

    1.2.1 What is Digital Audio Tape (DAT)?Digital audio tape (DAT), such as TLZ06 cassettes, takes advantage of the
    TLZ06 tape drive's helical scan technology. This technology allows data tobe
    stored diagonally on tape. As such, DAT allows more data to be stored ontape.
    Also, DAT recording minimizes ``crosstalk,'' providing you with more dataintegrity.

    1.2.2 What is Digital Data Storage (DDS)?Digital data storage (DDS) uses a recording format that supports the use of
    digital audio tape for computer applications. The DDS/DAT format allowsyou
    to back up 2 gigabytes of data in approximately 3 hours minimum withno
    operator intervention. In addition, this format has three levels of errorcorrection,
    which ensures high data integrity.


    ------------------------------------------------------------

    NOTE
    ------------------------------------------------------------


    Use of Non-DDS media may result in degraded drive performance andis
    not recommended by Digital Equipment Corporation.------------------------------------------------------------

    2.3 Selecting the SCSI AddressTo familiarize yourself with the TLZ06 drive:

    1. Refer to Figure 1-1 for the location of the buttons, switches, and
    connectorson
    the tabletop drives.2. Note that all connections are made at the rear of the drive.

    Your system uses a SCSI ID switch (Figure 1-1) to identify, or address, thedrive.
    The SCSI ID is factory set at 5. If you are installing the drive on asystem
    that is already using SCSI ID 5, use any available SCSI ID. (You mayhave
    to consult your system manager.)To set/change the SCSI address:

    1. Locate the SCSI address switch at the rear of the drive.2. Select the SCSI address for the drive:

    · TLZ06-DA -- Press the + or - button until the desired address (0through
    7) appears in the window.· TLZ6L-DA -- Set the switches according to Table 3-1.

    If you are installing any other drive variant, refer to Chapter 3.Turn off all power before connecting the cables and the terminator.

    The drive must be turned off and then on for switch settings to takeeffect,
    or a SCSI bus reset must be received.------------------------------------------------------------


    2-2 Installing the Tabletop Drives



    The tabletop drives provide two SCSI connectors to allow daisy chaining.Either
    connector can connect to the host computer or any SCSI device in adaisy
    chain.· If the tabletop is the last drive in the chain, a single interface cable
    isattached
    to one connector and a SCSI terminator (PN 12-30552-01) isinstalled
    in the other connector.· If the drive is within the chain, the interface cable from the preceding
    device is connected in one connector; an interface cable is also connectedfrom
    the other connector to the following device.


    ------------------------------------------------------------

    NOTE
    ------------------------------------------------------------


    Make sure that the last SCSI device on the bus is terminated correctly.------------------------------------------------------------


    2.4 Connecting a SCSI Signal Cable -- Drive to SystemIf you are connecting a TLZ06-DA drive or TLZ6L-DA auto loader
    directly to your system, you should use the SCSI signal cable suppliedas
    part of your system installation kit.If you do not have this cable, contact your Digital sales representative.
    Youshould
    use a cable supplied by Digital Equipment Corporation. Failure to doso
    can result in degraded performance of your tabletop drive.To connect a SCSI cable -- drive to system -- perform the following:

    1. Connect one end of the cable to the system SCSI connector.2. Connect the other end of the SCSI signal cable to either SCSI connector
    onthe
    rear of the TLZ06-DA drive or TLZ6L-DA auto loader.3. Secure the SCSI cable by snapping the wire cable clamps (on either side
    ofthe
    SCSI connector) into place.4. Connect the SCSI terminator to the other SCSI connector on the rear of
    the TLZ06-DA drive or TLZ6L-DA auto loader.5. Secure the terminator by snapping the wire cable clamps (on either side
    ofthe
    SCSI connector) into place.

    Preventive Maintenance and Problem

    Solving

    This chapter describes preventive maintenance and problem solving for theTLZ06
    cassette tape drive. Preventive maintenance involves periodic headcleaning.
    Problem solving is described in Table 6-1.Statistics show that over 90% of drive-related problems are associated with
    themedia.
    Therefore, Digital Equipment Corporation strongly recommends thatyou
    follow the instructions for handling cassette tapes and cleaning the headsof
    the drive.

    6.1 Cleaning the HeadsThis section shows you how to perform TLZ06 head cleaning. The heads are
    the components that physically read and write data to and from the media (inthis
    case, a cassette tape).Digital Equipment Corporation recommends that you perform the
    head cleaning procedure about every 2 weeks, or after every 50 hoursof
    drive usage.Under normal conditions, it should not be necessary to exceed this
    cleaning schedule. If a particular data cassette causes problems, trychanging
    to another data cassette.

    Preventive Maintenance and Problem Solving 6-1




    ------------------------------------------------------------

    CAUTION
    ------------------------------------------------------------


    Never attempt to clean the heads in a manner other than describedherein.
    Doing so will void the product warranty.------------------------------------------------------------


    To clean the heads, use the head cleaning cassette as follows:1. Press the power switch ON to apply power to the drive.

    2. Insert the head cleaning cassette (PN TLZ04-HA) into the drive.3. With the head cleaning cassette inserted, the drive automatically
    executes head cleaning. The drive ejects the head cleaning cassetteafter
    approximately 30 seconds.4. Locate the card enclosed with the head cleaning cassette. Place a check
    mark on the card every time you use the head cleaning cassette.Under normal conditions, the head cleaning cassette is used for about
    25 cleanings. Additional cassettes are available from your Digital salesrepresentative
    or DECdirect.If the head cleaning cassette has been overused, both the Cassette and
    the Write-Protect LEDs will flash. Press the eject button to remove thecleaning
    cassette. No cleaning action will have occurred.

    Choose your labels and place them on the bezel as shown inFigure
    7-1. (The dot matrix display also supports the same four languages.)The Data Compression LED is lit when data compression is enabled on the
    TLZ06 tape drive. Both the Data Compression LED and the LED to its rightflash
    rapidly when a loader fault occurs. The Reserved LED is reserved forfuture
    use. The Write Protect and Cassette LEDs are described in Chapter 5,Using
    the TLZ06 Cassette Tape Drive.

    7.3 Dot Matrix DisplayThe indicators (Section 7.2) and the dot matrix display support the same
    fourlanguages.
    The dot matrix display shows two types of messages: activity andstatus.

    7.3.1 Activity MessagesThe dot matrix display has several activity messages: READ when the drive is
    reading, REWIND when it is rewinding, and so forth.

    7.3.2 Status MessagesThe dot matrix display shows the current status of the auto loader when the
    drive is not active. Table 7-1 lists the status messages.

    Table 7-1 Status Messages------------------------------------------------------------

    Message Meaning------------------------------------------------------------

    TLZ6L Auto Loader 7-5



    7.4 OperationThe TLZ6L auto loader can be operated two ways: automatically or manually.
    It has two modes: Sequential and Random Access.

    7.4.1 Automatic OperationsDuring automatic operations, the TLZ6L auto loader can function in
    Sequentialand
    Random Access modes at the same time.In Sequential mode, upon receipt of a SCSI unload command, the loader
    unloads the current cassette and automatically cycles to the next cassette
    inthe
    magazine. It continues to unload and cycle to the next cassette until thelast
    cassette has been unloaded. When this process is complete, the magazinestops
    to prevent accidental overwrite of data. Then the magazine may beunloaded.

    In Random Access Mode, the loader responds to all of the SCSI Random AccessCommands.

    7.4.2 Manual OperationsManual operations are performed from the front of the auto loader.

    To load a magazine, press the eject button. This opens the drawer and ejectsany
    magazine that is in the drive. Then place the magazine in the mouth ofthe
    loader until the rollers engage the magazine. The loader automaticallyscans
    the magazine to make sure the cassettes are loaded correctly and tocount
    the number of cassettes loaded. The loader displays the number ofcassettes
    loaded. If a 4-cartridge magazine is installed, the drawer closes. Ifan
    8- or 12-cartridge magazine is installed, the drawer latches in the openposition.

    To load a cassette, press the slot button. Press it once to load the first
    cassette,twice
    to load the second cassette, and so on. If you make a mistake, continuepressing
    the slot button until the current state is shown on the dot matrixdisplay.
    When you press the slot button, the loader displays the selected slotand
    allows some time for changes. Then the selected slot is automaticallyloaded
    and the drive becomes ready.To eject the magazine, press the eject button. This ejects any cassette that
    isin
    the drive, opens the drawer, and ejects the magazine. Then you can removethe
    magazine.

    7-6 TLZ6L Auto Loader



    7.4.3 Single Cassette OperationIf a magazine is in the drive, eject the magazine. When the mouth of the
    loader is empty, you can load a single cassette in the drive. The drive
    shouldaccept
    the cassette and load it.To eject the cassette, press the eject button. The cassette moves into the
    mouthof
    the loader. Then you can remove the cassette.

    7.5 Switch Settings

    7.5.1 Switchpack 1Switchpack 1, or SW1 (Table 7-2), is located at the top of the drive. It is
    accessible through a cutout in the top cover of the drive. The drawer must

    7.6 Routine Maintenance

    7.6.1 Cleaning the RollersDigital Equipment Corporation recommends that you clean the rollers about
    once every 6 months or after 10,000 load/unload cycles. Follow these steps:1. Open the drawer and remove the magazine.

    2. Dip a cotton swab in ethyl alcohol.3. Press the slot select button three times in a 3-second period. This
    startsrotation
    of the cassette rollers. They rotate for 15 seconds while the displayreads
    CLEAN 1.4. Wipe the rollers with the wet end of the swab for a few seconds as they
    rotate.5. Wipe the rollers with the dry end of the swab for a few seconds as they
    rotate.6. Again, press the slot select button three times in a 3-second period.

  6. Re: Difference between DEC TLZ06-AA & TLZ07-AA

    Alex,

    Do you know if the BA353 StorageWorks model of either the DEC TLZ06 or
    TLZ07 can be adapted to fit into any other type of external enclosure?
    Can the drive be removed from the StorageWorks bracket or is the drive
    faceplate integrated with the bracket? Reason I am is asking is that I
    have seen several BA353 StorageWorks enclosures up for sale that have a
    drive included, because of existing space issues on and around my desk I
    was thinking of pulling the drive and installing it into a smaller single
    bay enclosure.

    Thanks again... - Jim

    I'm sure it would work in any StorageWorks unit supporting that size SBB's
    (Storage Building Blocks), the BA353 (often referred to as a Pizza Box) is
    pretty much the smallest external unit you will that supports them. Most
    others such as the BA356, BA350, BA346, et al are much larger.

    The only other unit that is perhaps smaller than the BA353 is the BA362
    (Height 10.5", Width 7", Depth 12.67"), which supports 2 SBB's rather than 3
    in the BA353.

    I have over the years, removed many disc drives from their SBB's, and
    subsequent installed them inside various VAXen and Alpha's, that procedure
    has always been successful.

    I have not however done this with a SBB mounted TLZ06/TLZ07, but it should
    be possible, although you would need to pay specific attention to
    connectors, termination, type of SCSI controller in your target hardware
    (single ended , differential, fast, wide, narrow, ultra) etc etc
