DAT 72/DDS-4 Product Manual
Clean LED
If the Clean LED is ON continuously, the drive requires cleaning. Use only an
approved DDS cleaning cartridge. Following is a guideline for cleaning intervals
based upon drive type:
•
DDS-4
DDS2, DDS3, or DDS4 media has been operating in the drive for at least 50
hours.
•
DAT 72
DDS3, DDS4, or DAT 72 media has been operating in the drive for at least 50
hours.
If the Clean LED is flashing slowly (approximately ON 2 seconds, OFF 1 second),
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 compromised.
If you see this signal, remove the tape at your earliest convenience and clean the
drive using an approved DDS cleaning cartridge. If, after cleaning the drive and
reinserting the original data cartridge, the Clean LED still flashes, you should use a
new cartridge for future backups.
If the Clean LED flashes rapidly, a cleaning cartridge that has exceeded its useful life
has been inserted into the drive. Replace the cleaning cartridge with a new approved
DDS cleaning cartridge.
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 to the tape correctly
(maximum rewrite count exceeded), and the write operation failed. Clean the
drive heads using an 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 50
hours of operation.
Drive LED
•
If the Drive LED is ON continuously, the drive is reading from or writing to the
tape (that is, SCSI or tape movement is present). If you push the eject button
while the Drive LED is ON, you might lose data.
Note:
If your backup software issues a SCSI Prevent Media Removal command,
the Drive LED remains ON and the eject button is disabled so that the tape
cannot be accidentally ejected. To eject the tape, use you backup software’s
Eject function.
