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.
