Issue with Airport Extreme Base Station and LaCie drive

Why won't my Airport Extreme Base Station, recognise my LaCie 750GB D2 drive? I have owned the drive for months, and never had a problem using it directly attached to my Mac. I have reformatted the disk (Mac OS Extended) and used the base stations USB connection for other devices without any issue. LaCie support say this is a known issue and the issue is with the base station.
 
sad I’m frustrated
