WHAT IS THIs??????

i ran sisoftware sandra and i got a warning under ata/atap info.
it said this

Warning W3104 - Current transfer mode not optimal, i.e. not highest supported. This affects drive performance. If the controller is also capable of the highest supported transfer mode, there is no reason not to use it.
Fix: First check controller supported transfer modes. Then check the mode the driver for the controller/BIOS is set to use and modify; some default to a lower mode for compatibility. You may need to install newer drivers if the current drivers do not natively support the controller (especially for RAID). You may need to update the controller BIOS or drive firmware, if the mode does not stick. If data corruption occurs verify the cable and consider switching (if any) drives on the same channel onto other channels.

If the built-in controller does not support the mode, consider using the on-board/RAID controller or even disable the built-in controller and install a new controller.

tell me what i need to do because i think this might be the problem with my computer



SiSoftware Sandra Help File

 

This won't cause any problems. However, it might slow your hard drive transfer rate down a little. If you can post a picture of your IDE drives in Sandra, it would help.

My guess is that you have a CD/DVD drive plugged into the same cable as your hard drive. This causes the hard drive to transfer at the same speed of your optical drive.
