Re: Tape at hardware path : Not Data Grade

The first thing is very clear that the error is related to the tape only.
Possible causes:
1) The Media (Tape) inserted is a cleaning media
2) OR the media does not have the proper
header i.e. it can be either a Audio grade OR a video grade.
3) The media may be of data grade but a bad media which is not properly factory initialised to be used as a data media (tape).

Re: Tape at hardware path : Not Data Grade

MRS stay for Media Recognition System, and this is the system used on DDS tape to identify a Data Tape Vs a Audio Tape.
the cartridge have several hole on the shell that the drive will recognize with some microswitchs.

So the problem may be related to the tape, which is an audio tape, without the MRS, or you may have some problem with these microswitchs.
