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 backward-

read 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.

www.dell.com | support.dell.com

NOTE: In Table 1-3, the media types formatted in bold can read and write Type IV media only.

NOTE: In Table 1-3, the media type formatted in italics can read and write VS1 media. It can also read

Type IV media written by VS or DLT1 drives.

NOTE: In Table 1-3, the media types formatted in underlines can read and write SDLT media. They can

also read Type IV media written by DLT4000, DLT7000, DLT8000, VS80, and DLT1 drives.

1 Orange alert/media light comes on.

2 The orange alert/media light illuminates and the tape is automatically ejected. The alert/media light will go off if readable

media is inserted into the drive or power is cycled on the drive.

3 No lights will come on. The drive automatically ejects the tape.

4 No lights come on. Backup software shows bad media.

5 Orange (220) LED blinks indicating that a 220 formatted tape is in the drive.

6 No lights blink. The tape does not eject. There is no indicator on the SDLT that would indicate no data on tape.

* 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.

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.
