Windows 7: Files Disappearing from Folders on external (USB) disks

Files Disappearing from Folders on external (USB) disks

I have just rebuilt a Windows 7 machine which has 2 separate internal HDDs. The second HDD is shared on my home network as my main data store.
I have 2 x 1TB external USB-connected drives to act as backups (used alternately).
All drives are NTFS and Windows updates applied to all machines.
I do the backups using xcopy to copy all new/updated data files to the 1Tb drives from the main data store.
This arrangement has worked fine on previous machines, using different OSs (Server 2003, WinXP).
However, on the new (Win 7) machine, when I run an xcopy backup, sometime during the backup, the files on the external drive suddenly "disappear". This happens with either USB drive.
If I move the USB drives onto my main desktop machine, they work perfectly.
Also, the files are NOT missing - they just cannot be viewed by the "new" Windows 7 machine.
On the Microsoft site, I found a problem similar to this, but it only applied to XP, not Windows 7.
I also found another website describing a similar problem, but the thread finished with a comment that it was "a USB overload".
Any ideas, anyone?
