Just built a 25 foot drivewire cable and it works perfectly at this length I am not sure how long you can go with a DW cable but the 25ft works great I picked up 3 windows 2000 computers from my church. 2 Compaq and 1 IBM. I am going to use them as stand alone servers for my coco3, coco1, and TDP. Sent from my BlackBerry
