How do you have the 002 and hard drive connected? PC -> HD -> 002 or PC -> 002 -> HD Have you tried reversing the order of the 002 and HD? What is the file system on the HD? FAT32? NTFS? What is the cluster size on the HD? 4K, 32? other? There are lots of variables to wonder about. I run a Gateway 400SDX with my MBox, and the Firewire port is fine with my external NTFS formatted drive, but I'm not also running a 002 on that same port. The Firewire port on the 400x might not be fast or efficient enough to run both the 002 and a HD. If you've tried everything else, you might consider getting a Cardbus Firewire card to run either the 002 or the HD on. The 002 and 002R can be quite picky about the particular Firewire card they're running on. Mike
