80GB drive thinks it's 127GB

[tobenfun]

I run extra hard drives through an external firewire unit.
I've just bought and installed an 80GB Seagate drive which is up and running and seems fine, except that everything I run tells me that the drive is 127GB ("Disk management", "Norton", "Treesize Pro&quot. If I format the disk it only ever gets as far as 58%. I've tried more than one format programme. Norton can't find anything wrong with the disk and it seems to function correctly in all other respects.
I don't mind the PC 'thinking' it's a 127GB drive as long as it works reliably and won't let me down later on. Can anyone comment?
Thanks

Have you tried connecting drive on internal IDE connector & seeing if same - then if is, RMA it?

It's a laptop, therefore no internal IDE.
Please, what is RMA?
My main concern is, do you think that further down the line I might lose date stored on the disk?
