Re: IOmega



Unfortunately, I must agree with this.  I have had a 2gb jaz for 1.5
years or so.  I've replaced all of my disks twice, and the drive 4
times.  Granted, iomega is good about replacing the stuff, paying
shipping both ways and such, and when the disks and/or drive fails, you
only lose a few files, it is a big pain in the butt.  I still have my
jaz drive, I use it seldomly.  When it does work, which, for fairness,
is most of the time, it is great, but don't bank on being able to
recover the media.  I use it as temporary space.  

Iomega did tell me though that the problem could be related to a
compatibility with my adaptec 2940u2w, which at the time was an embedded
controller.  They had patches avalible, or, maybe adaptec had patches
avalible, but it didn't matter anyways, since they were only for the
retail 2940.
