Cannot write to or read from
tape.
• Make sure that the cartridge is write enabled (move the
write-protect switch to the enabled position).
• Make sure you have the appropriate data cartridge for your
1/8 Tape Autoloader model.
• If you have the 1/8 Ultrium Tape Autoloader, make sure you
are using an Ultrium cartridge that has not been degaussed.
Do not degauss Ultrium cartridges!
• Make sure that the cartridge has not been exposed to harsh
environmental or electrical conditions and is not physically
damaged in any way.
• Many backup applications do not read or write to cartridges
that were created using a different backup application. In this
case, you may have to perform an erase, format, or label
operation on the cartridge.
• Make sure you understand any data protection or overwrite
protection schemes that your backup application may be
using, which could prevent you from writing to a given
cartridge.
• Retry the operation with a different, known good tape.
• Clean the tape drive. See ” Cleaning the Tape Drive ” on
page 43 .

differential SCSI bus/host

• SCSI cable length exceeded, use shorter cable, or remove
other devices from the bus.
• Check for conflicting SCSI IDs.
• DLT VS80, Ultrium 960 and Ultrium 448 models: check that
the HBA supports LUN scanning and this feature is enabled.
• Device not properly terminated. See ” Installation problems” on
