9. If the problem is still there, the problem probably lies with the drive or the host computer.
Has the drive been moved recently? Have any cables been disconnected and reconnected? Has
the environment changed—unusually hot, cold, damp or dry? Has there been dust or dirt near
the drive. Have reasonable precautions against static been taken?
The problem could lie with the drive:
1. Check the cables and connectors.
2. Clean the tape heads with the cleaning cartridge.
3. If the problem persists, check the environmental conditions against the specified limits, see table
above or refer to http://www.quantum.com/ServiceandSupport/index.aspx. Perhaps move the drive
to a more suitable site.
Has a new operating system been installed in the host computer? Has new backup software been
installed?
The problem could lie with the host or the software. Consult the computer's operating manuals, the
software manual, or seek help from a service engineer.
