Fabiano,

First of all, it was a good thing to put it on a normal hard drive. 
NetBSD isn't so good from a Jaz drive. The first, and foremost reason, is 
that Jaz drives tend to "overheat" after being turned on for long periods 
of time. Very bad flaw, especially on UN*X systems which usually have 
uptimes of weeks or months...

That's pretty all I know about the Jaz. As to the fate of your cartridge, 
I'm not sure. It looks pretty bad, though. You may need to buy a new one. 
The Jaz is a very unreliable drive, in my eyes. I'm sure there are others 
who use it without these problems, but..

Sorry I could not be of more assistance!


Ciao!
