I'd have to agree with this, about a month ago I was getting these types
of errors quite frequently so I did a shutdown -h now and ejected the
removable ( a SyQuest EZ 135 ) cartridge only to find that the normally
bronze (maybe a shade of gold) was blemished by a rather large black
streak. After replacing the cartridge I no longer had these media errors.

I hope there is nothing wrong with your media but it's the first thing I'd
check after seeing such errors.

BTW, What type of mechanism/medium does a JAZ drive use I know a ZIP is
basically a *REALLY* dense floppy, and the EZ drives are actuall platters
but what does a JAZ have?

Bye.
