Hi.

Maybe the drive is to be formatted first?

Actually, that was the thing I did first, with my first external enclosure (a USB one), it didn't work. Windows just kept saying that it wasn't formated, so after I did reformat it while it was attached via USB (which wasn't that easy using Windows tools), it worked well. The FireWire enclosure, however, worked perfectly fine with a pre-formated and pre-partitioned disc (though I only defined one partition).

Maybe they have special drivers that handle this....?

Maybe, hopefully, that is. I would certainly ask for a refund if they wouldn't work the same (with data intact) with each cable.

cu,
sven
