Cannot write to or read from

Make sure that the cartridge is write enabled (move the write-

tape.

protect switch to the enabled position).

 

Make sure that the cartridge is a DLTtapeIV that has not been

 

written using an incompatible format. The drive can read, but not

 

write a DLT 4000 formatted tape.

 

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 36.
