OK. So it is in the new ntfs format which is a bit different to the one 
used in XP.

Sigh..... I should have been clearer.

Which *application* or *method* did you use to copy the files in Ubuntu? 
Did you use mc (Midnight Commander), or 'cp' on a command line, or 
Nautilus or Dolphin or what?

Linux (ie, Ubuntu et al) does not give an error message 'run chkdsk /f' 
- this is only used by Windows.

How exactly did you try to mount it in Ubuntu? That is, what is the 
command you used in a terminal to try and mount it? Please spell out the 
exact steps and commands you used to try and mount the HDD.

So Ubuntu recognises the external HDD. But what device number does it 
give this HDD - sd<what>? sdb, sdc, sdd, sde or what?

Better still, post here the exact output of 'fdisk -l' which will give 
the details of all your storage devices.
