Drive Operation and Maintenance 27
Clean LED
The Clean LED functions as follows:
• If the Clean LED is ON continuously, the drive requires cleaning. Use only a
Seagate-approved cleaning cartridge to clean the drive, as described on page
31.
• If the Clean LED is flashing slowly, the tape cartridge currently in use has
exceeded a predefined soft-error threshold. This signal is a warning only and
does not indicate that data has been lost. If you see this signal, remove the tape
at your earliest convenience and clean the drive using a Seagate-approved DDS
cleaning cartridge. If, after cleaning the drive and reinserting the original data
cartridge, the Clean LED still flashes, then you should use a new cartridge for
future backups.
Media LED
The Media LED functions as follows:
• If the Media LED is ON (lit) continuously, a DDS cartridge has been inserted and
the drive is operating normally.
• If the Media LED is flashing rapidly, the drive could not write the tape correctly
(maximum rewrite count exceeded) and the write operation failed. Clean the
drive heads using a Seagate-approved DDS cleaning cartridge. If you reinsert
the original data cartridge and the LED continues flashing, insert a new data
cartridge and retry the operation.
Note: As routine maintenance, you should clean the drive heads after every 25
hours of operation when using DDS-1 or DDS-2 tapes or after every 50
hours when using DDS-3 or DDS-4 tapes.
Drive LED
The Drive LED functions as follows:
• If the Drive LED is ON continuously, the drive is reading or writing the tape (that
is, SCSI or tape activity is present).
Caution. If you push the Eject button while the Drive LED is ON, you will interrupt
any host operation, causing an application error. It may not be possible
to append to the tape if a write operation is aborted in this way.
Note: If a SCSI Prevent Media Removal command has been issued, the Drive LED
remains ON and the eject button is disabled so that the tape cannot be
accidentally ejected.
• If the Drive LED is flashing rapidly, a hardware fault has occurred. If this occurs
immediately after powering on the drive, then the Power-On Self Test switch is
enabled and a Power-On Self Test has failed. The front panel LEDs may be
flashing together. If this occurs contact the Seagate Technical Support
department for information. If the Drive LED is flashing rapidly during drive
operation, you should attempt to remove the tape by pressing the Eject button. If
the tape does not eject within 2 minutes, press and hold the Eject button
