I currently run a multi-boot system on my PC. One partition is my general everyday use XP setup, the other partition has a bare XP setup. Both are fully up to date. I use the bare setup as an emergency in case of problems, malware attacks etc. Being able to access the web and system files from another partition has proved a lifesaver more than once.
I have recently come across a strange problem. I purchased a Western Digital USB2 external hard drive (160gb). My everyday XP setup would only recognize the unit as an unknown device, when using the mobo USB ports, and it would not show in explorer regardless of what I did, including registry modifications and forced driver installs etc. So before I took it back, I unplugged it, I booted into my bare XP partition and plugged the drive back in. It was instantly recognized and worked flawlessly.
After a couple of frustrating evenings trying to find a solution, I went and bought a Belkin USB2 pci card with an NEC chipset. Installed it on both XP setups, plugged the drive in and it was instantly recognized on either setup. On my bare XP installation, I can plug it in to any USB2 port i have, yet on my everyday setup, it only works from the NEC card, not from the mobo ports. So in essence, I have partially solved the problem, and can use the drive, but I am very curious as to what may cause this. The only bit of hardware that is not common to both XP setups and requires a driver, is my Zen Micro Mp3 player. I have no intention of installing it on my bare XP system. Could the ZEN`s USB2 drivers be causing some kind of problem? A brief description of my setup is below.
Anyone any ideas what may be causing this? I hate things like this. There must be an explanation. I built the PC myself and this is the first time I have come across a problem that I could not find an answer for.
