Hard Drive Help Pages

7. I have hard drives and CD roms of differrent modes are there likely to be any problems mixing the modes?

In Theory there should be no problems at all mixing hard drives and or CD roms of different modes although copying files between 2 drives can of course only proceed at the slower of the 2 drive modes. However in practice there are occasional problems with this though they seem only to occur when the primary master drive (Hard drive C) is not the fastest (or equal fastest) mode drive on the system. Although these problems only occur in a small percentage of cases it is still advisable that you make your C drive the fastest one on the system since if nothing else it will cause windows and other programs on the C drive to load up faster. There is also a possibility of a problem with UDMA66 drives on motherboards that only support up to UDMA33 drives. Once again in theory the UDMA66 drive should run correctly as a UDMA33 drive but there are occasions when it will not. Some drives have settings (or sometimes utilities) that will specifically tell a UDMA66 drive to behave as a UDMA33 drive.
