Head Cleaning
4.6.1.
In case of SDX-800V,a cleaning function which prevents and recovers from head contamination is built in the drive.
However, to keep optimum Read/Write performance, cleaning cassette is recommended to use.
Message When Cleaning Cassette is Necessary
4.6.1.1.
When drive displays cleaning cassette requirement, (Cleaning Request LED is on or in case of SCSI, CLN bit is set
at Request Sense.) use specified cleaning cassette (model name: SDX3X-CL)
4.6.1.2.
The condition of Cleaning Request
(1) Read/Write performance decreased.
(2) Every 100 hours of operation.
Note: (2) is enable when Periodic Cleaning Req Dip-SW is on. (Refer to 3.1)
Usage of Cleaning Cassette
4.6.1.3.
(3) Drive displays cleaning cassette requirement.
(4) When specified cleaning cassette is inserted, automatic cleaning operation starts and when it's over, the
cassette is ejected.
(5) One cleaning cassette can be used approximately 50 times in average.
(6) When the cleaning cassette is not ejected without doing cleaning, it is possible that there were no more
cleaning tape left. Since cleaning tape cannot be used twice, please insert new cleaning cassette in this case.
(7) SDX3X-CL can be inserted in other drives or consumer 8 mm drives, but you cannot expect good effect.
(8) The drive will not eject cleaning cassette for consumer drives or for any other format. "Cleaning is Not
Completed" is indicated by the Cleaning Request LED.
Troubleshooting Guide
4.6.2.
Problems encountered while operating the Sony SDX-800V tape drive fall into two categories: Operational problems
and Read/Write problems.
Operational problems include any conditions that prevent the tape drive from operating. Operational problems
usually are discovered the first time the drive is installed on a system or when the system configuration is changed or
physically moved.
Read/Write problems include conditions that effect the transfer of data to and from the tape drive. Commands such
as REWIND, REQUEST SENSE and UNLOAD perform normally but data transfers fail.
The following clauses describe the recommended procedures for solving operational and read/write problems.
4.6.2.1.
Operational Problems
The tape drive will not accept a tape cartridge
Withdraw the tape cassette and turn the power to drive off, wait 5 seconds, then back on. Observe the drive for a
normal power up sequence (see clause 4.3.4). If the LEDs do not light, check the power supply and power cable
connection. If the drive completes the power on sequence normally but still won't accept the tape cassette, the drive
may be defective.
