Windows XP Wants to format all mass storage d

HELP!!,
This is the LONG story,

I have windows XP and Windows Vista running as a dual boot, I have recently had to replace my mainboard as the first one failed this I thought NP, if I have to I will repair the windows installations to get em going again,
Well Vista took to the mainboard no worries XP on the other hand gave me a heap of grief during the repair install but in the end I copied the CD contents to a folder on the hdd and repaired from there and all went well, now windows XP functions properly except for one issue, any mass storage device that i insert it wants to format, wether it be a EXT HDD or mem stick or photocard even the camera as the device,

I have checked all these devices with the vista install and all works well, have checked them on another XP machine and all is well but on my XP intstall "Windows Needs to Format this device"

This is driving me nuts does anyone have a possible reason for this

I have run

Combo Fix
Norton Systemworks
CCleaner
Regcure

and updated all the USB host drivers to the intel written drivers from the Mobo cd,

Every other part of windows is fine just this stupid format request on MSD

I hope that someone out there has an idea to what I can do as I am done thinking of it and have no clue where to go except a full fresh install of windows which is not a real option at this stage

thanks guys for your time
