FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which cassette media should be used with Digital Equipment Corporation TLZ07-DA?
Use certified 4 mm DDS media supported by the drive, including the documented 60 m, 90 m and 120 m cassette types. Confirm the recording format before reusing existing tapes.
Can data compression always be assumed when using Digital Equipment Corporation TLZ07-DA?
No. Compression depends on the selected drive mode and host operating-system configuration, so verify the active mode before estimating capacity or reading existing media.
How should Digital Equipment Corporation TLZ07-DA be cleaned?
Use the approved TLZ04-HA head-cleaning cassette when indicated by the drive or when excessive tape errors occur. Replace an expired cleaning cassette rather than repeatedly reusing it.
How is the SCSI address set on Digital Equipment Corporation TLZ07-DA?
Use the rear SCSI ID switch to choose an available address from 0 through 7, then power-cycle the drive or issue a bus reset as documented.
How should Digital Equipment Corporation TLZ07-DA be terminated?
If it is last on the SCSI chain, attach the interface cable to one connector and the approved terminator to the other; terminate only the end device.
How should media be protected when using Digital Equipment Corporation TLZ07-DA?
Set the cassette write-protect tab before loading archival media, eject the tape through the normal unload procedure and never transport the drive with a cassette installed.
Why might Digital Equipment Corporation TLZ07-DA be unavailable to the host?
Check AC power, the SCSI ID, cable security and end-of-chain termination. For flashing fault indicators or repeated tape errors, clean the heads and test with known-good DDS media.
