content unrecognized / old tapes

Recommended Posts

I am pretty certain that this is a *SOFTWARE* issue. (I have cleaned the heads, shuffled the scsi chain, changed the power supply, refurbished the drive, etc. the list goes on and becomes rather embarrassing after a while).




All of my old tapes come up as "content unrecognized." Even the ones that were backed up on the same computer... I have upgraded to 9.2 (from 9.1 and older versions) but on other systems running 9.2, the tapes are recognized and work. I have tried turning off all the extensions that are unneccesary and I have upgraded to latest version of retrospect (5.0.201). Still unrecognized. Am I missing a driver? Is it something with the advanced driver kit? HELP!

Without details on your configuration, though, it is difficult to offer further advice.




Go through the troubleshooting suggested, and if you are still having problems, repost with the following information:

If an external device, please provide:
