plextor 40x12x40 in USB2 port
 

Looking for some help. Bought Plextor and MS Bundle mid 2002 from MTU, have tried to use on laptop I had bought for them and system locks up when trying to write to plextor. Anyone found way to get laptops to write to the USB2 cards on the notebooks? MTU hasn't been any help as of yet. Been through all the mfg's involved, all the lateest drivers, have been told it's always the othwer mfg's problem, like a big merry-go-round. HP notebook, 40G HD, 512RAM, XP. Woprks fine in the USB1 port, but didn't buy it to write at 4X, have a Yamaha quicker than that already. Any help would be appreciated.
