What is the format of the drive? If you launch Disk Management from the control panel - it should show partitions on the drive. Windows can access NTFS, FAT, FAT16, FAT32 and exFAT. If it was partitioned in a different format (i.e. Linux), it may not be recognizable.
It is FAT, in disk management it shows as Basic disk with 3 partitions but options to assign drive letter are not available. I only have the option to create dynamic disk and on the individual partitions to delete volumes. Unfortunately I have not got access to an XP at the moment. Previously in MAC format, it was formatted to FAT on a Win machine (not by me) and I have reformatted again to FAT on Ubuntu pc.
So still a little unclear on the Win7 facilities which I have not played around on much to date.

What are the sizes of the partitions? My suggestion to make things easier to share between computers is to use NTFS...Linux, MAC and Windows all recognize this partition format.
Here is a technet article on how to convert it: http://technet.microsoft.com/en-us/library/bb456984.aspx?ppud=4

Problem being Ubuntu cannot do an NTFS format and none of the win 7 machines will give a format option 
... If I can get XP emulation running under win 7 I guess that might help. It has a 200mb efi (?), 297.77gb primary and 128mb unallocated.
Technet article is xp anyway.
Googling brings up lots of advice to take drive back as faulty, one had done that and got same problem. So this seems to be a Win 7 peculiarity (no surprise I guess)

That has solved it. It seems having been previously formatted for a Mac Win7 could not cope with its format even though it had been reformatted. Just need to check it is OK on other win 7 laptops.
Thanks to all
To summarise.
1. Command line use diskpart to get rid of partitions.
2. Initialise.
3. Format.
