Many thanks for that suggestion. Things are better but still something not
right!
I can now see the drive in Explorer under "Computer", but it's shown as a
Removable Disk and claims to have no media.... So if I right click on it
and try to Open or Format, system tells me there is no disk and to insert
one...
In Computer Management things have changed a bit too. The drive now seems
to have two listings in the lower half of the window. It is shown as Disk 1
(Removable G

, No Media. To the right there is no information.
Secondly it is listed as Disk 2, Basic, 232 Gb, Online. To the right there
is the blue bar that denotes a primary partition and below a hatched block
showing the size, 232 Gb. Again I cannot perform any operations on it in
Disk management which gives a variety of obscure error messages when I try
to format or change drive letter.
None of this means much to me but I'm hoping something might ring a bell
with you? Any help much appreciated.
