I had the same issue with a Fry's $99 special 320GB USB2/FW exernal HDD. 
Since I need to mount it with WinXP, Linux, and "GENERIC" FreeBSD, I was 
somewhat stuck. The way I got around it was to reformat it to ext2 and use 
the Win32 ext2fs driver from SourceForge.  I considered NTFS, but the 
FreeBSD support for NTFS didn't look practical to use at the time - Jy@
