External Drive - 40Gb disk works but not 250Gb

I've previously added two home made external disks, a 120Gb IBM and a 300Gb Maxtor, to my Medion PC (Pentium 3Ghz, 18 months old) without any problem. I'm trying to add a 250Gb Hitachi Deskstar but nothing happens - even the fact that a USB device has been plugged in is not recognised. As soon as I replace the disk with a 40Gb Maxtor, it all works fine, so the case and connections don't appear to be a problem. I've replaced the Deskstar, thinking it was faulty, but exactly the same happens with the new disk and Add New Hardware doesn't find anything. I'm on XP Home. Has anybody got any suggestions, please?

I have experienced similar problems in the past and found that the drive had to be jumpered 'master' for the USB to see it.

Sorry, should have mentioned that the Deskstar is set to Master - jumpers A-B and G-H and drive is supplied set to Master anyway (unless the info on the Hitachi support site is rubbish).

You may need to setup the Drive from DOS with Acronis disc management software first

Looked at the Acronis site and it seems to assume you can see the disk in the first place which I can't (not from XP or DOS). I didn't have any problem with the 300Gb or 40GB Maxtors, both of which I formatted from within XP - the 120Gb IBM (a Deskstar which Hitachi now manufacture) was already formatted.

Does it show up in Disk Management?

No, it doesn't show in Disk management. The usual sound when a USB device is inserted or removed doesn't occur so I assume it isn't registering at all.
