I bought this Adaptec AFW-1430A FireConnect to transfer video data from a Sony DCR-HC62 Mini DV camcorder to a Thinkpad T60. The adapter accomplished the job easily and perfectly. Windows XP Professional recognized this Adaptec cardbus and there was no need for any external "driver". This PCMCIA cardbus has 3 IEEE 1394 Firewire ports and a DC power jack for optional external power adapter. I did not need to use the power jack for transferring the video data to my computer. I assume the power jack may be needed for some other tasks requiring more power??. In summary, this card provides 3 firewire ports, is recognized by Windows XP, it is well made, and reasonably priced. Just make sure your computer accepts CARDBUS rather than ExpressCard.
