I have an HP Pavilion laptop (model ze4430us) / mobile AMD Athlon XP2400+ 518MHz 448 MB of RAM, running Windows XP Home Edition Version 2002 Service Pack 3.
I have an external DVD/RW, Sony DRX-810UL, as well as a JVC digital camera (GR-D270) which I've used successfully connecting to my laptop via FireWire/ieee 1394, until now.
The computer no longer recognizes either device. I've uninstalled the driver in the device manager, plugged in the device, restarted the computer, the computer finds new hardware (Texas Instruments OHCI Compliant IEEE 1394 Host Controller) and when I direct it to scan for hardware changes, nothing is found.
I've searched this problem on the Internet and see that many people developed problems with their FireWire devices after SP 2, and that Microsoft has a hoffix, but I am not confident enough to try this procedure without some technical assistance.
The laptop is my only computer, and I don't want to have to reformat it if I can avoid it. I also don't want to crash it and loose everything stored on it.
Assistance would be greatly appreciated.
