I have a 320GB Seagate external harddrive that shows 298GB in the Windows XP Explorer window (as it should) but when I right-click the drive and select "Format..." it only offers the "Capacity" option of 232GB! (as if it thinks I have a 250GB drive). Is this a Windows problem? Is there a way for me to format to the full 298GB? Many thanks in advance for your help!
