Invalid Media Symptoms - what happens when the wrong media is inserted into a drive
• Cleaning light comes on
• Media light flashes or stays on
• Tape ejects
Reusing Type IV Media Formatted by DLT7000 or DLT8000 in
VS80/DLT1 Drives
• By default, Type IV media previously recorded by a DLT7000 or DLT8000 is not read compatible with
DLT4000, DLT1, or VS80 drives
• Cartridge automatically ejects from the DLT1 and VS80 drive
• VS80/DLT1 drives can read Type IV media originally formatted in DLT7000 and DLT8000 drives only if
drive compression was set to 20GB. A tape formatted in 20GB mode appears as a write-protected tape and
is not writeable in a DLT1/VS80 drive. It is, however, readable. Otherwise media will continuously be
ejected from the DTL1 and VS80 drive.
• Bulk Erasing (degaussing) Type IV media previously used in other drives results in what the drive sees as
new media and is usable in DLT1/VS80 drives.
