Invalid Media Symptoms
When a wrong media is inserted into a drive:
•
Cleaning light comes on
•
Media light may flash or stay on
•
Tape ejects
Reusing Type IV Media Formatted by DLT7000 or DLT8000 in VS80/DLT1 Drives
Type IV media previously recorded by a DLT7000 or DLT8000 are not read compatible with
DLT 4000, DLT1, or VS80 drives.
Type IV media originally formatted in DLT7000 and DLT8000 drives can be used in a
VS80/DLT1 drive only if the media is first set to hardware compression level 20 GB and erased in
the DLT7000/8000 drive. Otherwise the media will be automatically ejected from the DLT1 and
VS80 drive.
DLT1 and VS80 Drives
DLT1 and VS80 drives use Type IV media to read and write.
DLT1 and VS80 drives can backward-read Type IV media created by DLT4000 only. They cannot
read the media formatted by DLT 7000 and DLT 8000 unless the hardware compression level
has been changed. See "Reusing Type IV Media Formatted by DLT7000 or DLT8000 in
VS80/DLT1 Drives."
VS160 Drives
VS160 drives use VS1 media to read and write.
VS160 drives can read Type IV media only if the media was formatted by DLT1 or VS80 drive.
They cannot read Type IV media formatted by DLT4000.
They cannot write to Type IV media. If a blank Type IV media is inserted in the VS160 drive, the
media light will flash and media will be ejected from the drive.
SDLT320 and SDLT220 Drives
SDLT320 and SDLT220 drives use SDLT1 type media to read and write. They can backwardread all Type IV media written with DLT (DLT 4000, DLT 7000, DLT 8000, DLT1, and VS 80)
drives.
SDLT320 drives can read media created with the SDLT220. When media created with the
SDL220 is present in the SDLT320 drive, the media light will come on.
SDLT220 cannot read media created by SDLT320. No warning is given from the drive, but
backup software will indicate bad media.
NOTE: Always label where media was originally used and formatted.

* Under default settings the DLT 7000 and DLT8000 drives write to tape in their default density. 70 GB 2:1 compressed and 80
GB 2:1 compressed respectively. Tapes written by these devices may be read by DLT4000, DLT1, and VS80 if density 20.0 is
selected on the front panel of the drive prior to formatting the tape media with a DLT7000 or DLT8000 drive. This will be data
destructive.
** Density selection is not mechanically available on the front panel of SDLT drives. However, for backward compatibility
reasons, an SDLT320 Density Select Utility is available on Quantum's website in the SDLT320 download area. This software
utility will allow an SDLT320 drive to write in an SDLT220 format. The utility is available for both Microsoft® Windows® and
Linux platforms.

Dell PowerVault DLT, VS, and SDLT Media Handbook Version 2.0
Cleaning Considerations
DLT tape drives do not need periodic cleaning. Only clean DLT tape drives when a request is
made by backup software, when a cleaning indicator is seen on the drive, or when
troubleshooting. Although DLT 4000/7000/8000/DLT1 and VS80 drives use the same Type IV
data media, they do not use the same cleaning tape.

Exhausted Cleaning Media
If a cleaning tape is inserted into a DLT/SDLT drive and the light remains on after tape eject,
the cleaning tape may be exhausted. See the following to determine that you are using the
proper cleaning tape for your drive type. If so, try another cleaning tape. Depending on the drive
model, if the light does not go off, there may be a hardware fault in the drive or expired media is
being used.
8
Dell PowerVault DLT, VS, and SDLT Media Handbook Version 2.0
When an expired cleaning tape is used in a:
•
DLT4000/DLT7000 drive, the tape is ejected and the cleaning light stays on.
•
SDLT220/SDLT320 drive, the tape is not ejected and the cleaning light goes out the 20th
time (last) the tape is used.
•
DLT1/VS80 and VS160 drives, there is no method to determine that the cleaning tape is
expired except to manually note usage on the check box label. It is the customer's
responsibility to record usage of the cleaning tape and discard after 20 uses. The cartridge will
have little or no effect on head cleaning after the recommended 20 uses.

Media Care Guidelines
DLTtape cartridges are engineered to be reliable, robust, and durable. They are manufactured to
withstand 1,000,000 passes, and have a shelf life of 30 years. For best results, follow these
guidelines for media care:
10
•
Protect cartridges from shock, vibration, moisture, and magnetic fields.
•
Keep media in protective cases and store vertically when not in use.
Dell PowerVault DLT, VS, and SDLT Media Handbook Version 2.0
•
Use the slide-in labels provided. Do not use adhesive labels or Post-it notes, and do not write
on the cartridge.
Figure 1-16.
Use Slide-in Label
•
Write in pen not pencil. Using a pencil can introduce contaminants to the tape path.
•
Use caution so loose labels in storage container don't stick to bottom of cartridge, covering
the hub.
•
Never touch the tape or tape leader. Dust and oils from your skin contaminate the tape and
affect performance. Store media vertically in protective plastic cases.
Figure 1-17.
•
Store Media Vertically in Protective Plastic Cases
If you drop a cartridge, perform a visual media inspection before inserting it into the drive.
NOTE: The safety of your data relies on proper care and handling of media cartridges.
Visual Media Inspection
A visual media inspection is to be performed:
•
Each time a tape is loaded or changed.
•
When a tape cartridge is dropped or subject to a hard physical shock.
•
When a shipment of tapes shows any sign of shipping damage.
•
If the DLT, DLT VS or SDLT drive becomes inoperable after loading a tape.
NOTE: If a drive error occurs, inspect the current and previous cartridge used in that drive.
Dell PowerVault DLT, VS, and SDLT Media Handbook Version 2.0
11
www.dell.com | support.dell.com
Cartridge Inspection
•
Case: Inspect the case for cracks, chips, or signs of damage.
•
Cartridge: Inspect the exterior of the cartridge for chips, cracks, dents, or missing screws.
Gently shake the cartridge. Listen for rattling or loose pieces.
•
Cartridge Door: Ensure that the door is moveable and that the spring is present.
•
Write Protect Switch: Move the switch. It should snap into write-protected mode and writeenabled mode.
•
Cartridge Leader: Gently inspect the cartridge leader to verify that it has not been damaged
and is in the correct position.
•
DLTtape Cartridges: Check the height of the leader to ensure that the loop is sticking up
approximately 3/16 inch or 4 mm. Ensure that the door operates. DLT tape leader loop
should be visible and undamaged.
•
Super DLTtape Cartridges: Check that the Super DLTtape leader buckle aligns with
cartridge edge and metal pin is not bent.
NOTE: When inspecting the cartridge leader do not use anything that could leave contamination,
such as a pen or pencil.

SDLT Media
When inspecting an SDLT media cartridge, refer to the following diagrams to check the leader
buckles on the media.
Figure 1-28 shows a good cartridge. Note the plastic hooks resting on the cartridge rails and bar
parallel to the cartridge.
Figure 1-28. Good SDLT Leader Buckles
bar
hooks
Tests have shown that dropping the media can cause an excessive amount of stress to the
spring-loaded cartridge hub on impact. This amount of stress will pull the tape media further
into the media cartridge and bend the leader buckles.
See Figure 1-29 to identify bent-in leader buckles. Note that the plastic hooks are bent inward
and not resting on the cartridge wall. Also the bar is not parallel to the cartridge. It is usually the
HUB side of the cartridge that gets more pulled.

Media with bent-in leader buckles have been known to cause the tape drive to drop the leader
when the drive tries to load the media into the take-up reel.
Cartridge Storage
When storing cartridge, avoid moisture and direct sunlight. Exposure to moisture or sunlight
can deform or ruin media.
