Hopefully someone can help.

I can read my N800 with an 8gb SDHC on my desktop running XP MCE, a laptop running Vista and another running Ubuntu. However, the laptop that I need it to work with (running XP Home), is intolerably slow when reading the device. Upon plugging it in, the "Removable Drive(s)" appear, but clicking on it in My Computer freezes Windows. It does eventually enter the folder, but ever so slowly and I know this isn't normal. Even Disk Management in the Control Panel lags when reading the device. After unplugging the USB cord, Windows will "unfreeze". It's not the card that's the problem because it reads fine in my camera when the camera is plugged in via the same USB cord.

Things I've ruled out:

1. Windows being unable to read SDHC over 8gb; it read the card fine through my digital camera.
2. Problem with N800 connecting to Windows; reads fine and fast on my desktop with XP MCE.

Thanks for any feedback.

Edit: Forgot to include that my tablet is running OS2008.
