No, everything is the same since the last time it was working. This seems
to have come up out of the blue. I don't think I did anything since it was
working right.
It seems to be the same in more than one usb port.
Any thoughts on what I might check?
Thanks,

Bob:
The following will probably be of little help to you with your problem but
let me cite our experiences over the past two years or so with USB 2.0
devices, particularly as they affect jump (flash, thumb, memory, etc.)
drives and USB external hard drives...
We have continually run into situations where apparently non-defective USB
2.0 devices connected to apparently non-defective USB ports in apparently
properly-configured systems simply don't originally work, or stop working
after a period of time, or work erratically, i.e., sometimes they do,
sometimes they don't. For no accountable reason, the device will work in one
machine and not in another. It's been an aggravating problem for many of us
because we can't seem to find a common denominator to explain all these
anomalies. We hardly ever ran into these problems with USB 1.0/1.1 devices,
but of course the number of those devices in use at the time was a fraction
of the number of USB 2.0 devices presently in use.
We are fast coming to the conclusion that either there must be some
fundamental incompatibility inherent in the USB 2.0 specification that is
causing these types of problems as it involves the design and manufacture
of these USB devices, and/or the system protocols and devices that are
employed to work with these devices are defective in some way. Or perhaps
it's just a matter of poor quality control in the manufacture of these
devices (even extending to the same make & model of the device involved) in
that sometimes they work; sometimes they don't. Or perhaps some
incompatibility existing between the XP OS and the USB 2.0 specification
that results in these puzzling occurrences.
Anyway...
In your particular case, as has been recommended - if you can, connect the
device to another machine and see if it works. Do you have a jump drive or
other USB device that you can connect to your computer's USB port(s)? What
happens then? If it seems that the hard drive may be defective, can you
remove it from the enclosure without voiding the warranty and connecting it
as an internal drive to test it? Have you tried uninstalling the USB
controllers in Device Manager, and rebooting, so that the OS will re:install
those controllers? Have you been in touch with Iomega re this problem?
