I have an Acer Aspire 5600 and have recently re-installed XP Professional, I have installed all drivers that came with the Laptop first day and I have run a driver detector tool to look for upgrades. Yet the Mass Storage Controller driver is stilll showing up as missing. it's an Intel Centrino Duo with the Mobile Intel 945GM/PM Express chipset. I have installed the driver for the chipset from the Acer website yet windows still doesn't detect it. Any help would be appreciated.
