I was provided a Western Digital USB 2 / Firewire exernal disk
drive (250GB) to do some testing on Linux (Redhat 9) but I cannot
get started good.
I put on all the latest 'up2date' fixes and at least the system now
recgonizes that I have a USB controller on it.  In  /var/log/messages:

So it found the device and is trying to define it as /dev/sda, but
then I get...

the "scsi: device set offline" does not sound good....

Then I get a number of slight variations of:

If I try to:  fdisk  /dev/sda
I get a "unable to read..."  message.

Any suggestions how to get this device available??  I'd like to to
put a standard filesystem on it and be able to mount /umount as required...

Thanks
Mike
