Troubleshooting Guide
4.5.2.
Problems encountered while operating the Sony SDX-460V 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.
4.5.2.1.
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.
A tape may already be in the drive. TAPE MOTION LED is on. Press EJECT to remove the first tape. The power has
been removed from the drive with a tape loaded. When the power is restored to the drive, it will detect the tape and
rewind the tape to BOT. Press EJECT remove the cassette.
