The reinstall was successful but for some reason the computer will not
read the USB HD. It did before without me having to do anything
especially "Linuxie". I have unplugged and plugged in the drive both
at the drive and the computer connections, without success. The hard
drive light is on.

I have searched Google for "mounting external usb drive" but without
success.

If I go into a terminal and type lsusb i get

zed@zed-desktop ~ $ lsusb Bus 002 Device 004: ID 058f:6387 Alcor Micro

if that is any use. All I can recognise is the usb flash drive and HP
printer. I presume that the USB 2.0 IDE Adapter is what allows the
other USB devices to register. The external hard drive doesn't appear.

So, your mission, should you choose to accept it, is to tell this
floundering geriatric what other avenues are open to him to solve this
problem.

Install a "proper" distribution?! ;-)

It is :-)


Plug in the hard drive, give it a few seconds, then do 'dmesg' - that
should scroll loads of log stuff up your screen, but it's the last few
lines you're interested in. It should register that a USB device has been
plugged in. It should also say something about the nature of that device.
Ideally, it should say it's attaching it to a scsi port.

Did as you suggest and got:

and then doing a lsusb I get

Bus 002 Device 004: ID 05e3:0702 Genesys Logic, Inc. USB 2.0 IDE Adapter
Bus 002 Device 003: ID 058f:6387 Alcor Micro Corp. Transcend JetFlash 110
USB 2.0 Flash Drive (2GB)

What is taht flash drive? Why is it permanatly plugged in? Try removing it

Then look for a scsi disk
ls /dev/sd*

It looks like it is /dev/sdd.
See if there are any partitions /dev/sdd1, sdd5,...
Mount one of them (as root) somewhere
mount /dev/sdd1 /mnt/hd
or whatever you have there.

Sorry to be a pest but "what now"?
