Wireless adapter and hard drive stuff

hey, anyone get spontaneous loss of their secondary drive? just all of a sudden windows decides its not formatted and poof all your stuff is gone?

and is anyone using this hardware with windows xp: USR8054 (wireless router). and the 802.11g Wireless Turbo PCI Adapter. Or know of anyone, I’m having problems with the card, it keeps disappearing and saying the device cannot start, then when i restart and check for new hardware it shows up and it works for another day or two.

whats a fix, aside from throwing my computer off the Sears tower here in vancouver?
