I just got a customer 98 machine in that booted but did not open word or quickbooks. Placed it on our XP pro machine and niether the windows explorer or the Vii backup utility could see it. It passed the Western digital utility smart testing and the quick test and the physical disk was visible in Disk management. I checked activate disk and got 9.xx GB of unallocated data and now the disk will not boot in the customers machine
