[m16si]

Please help me i have 2 hard disks and i have multi-word dma mode 2 which has lousy transfer mode how can i make it Ultra-DMA mode 5 which has 100.00 mb of transfer per second if im correct ?

Correct me if im wrong !

I have already have conductor 80 cables !

But is it the hardware or bios or something else ?

I take for granted that you already set in device manager that particular HD as "Use UltraDMA".

On some motherboards (actually very few, but VIA Mini ITX are an example) it might be needed to update the BIOS.

Also, it is possible that the chipset driver has to be updated.

Download and use this HDTUNE:

You will see at what Speed your HD is capable of working and at which one it is currently working.

Usually all you have to do is set the BIOS to auto-detect the IDE drives, and then make sure you have the latest chipset drivers installed. But, as with everything else, there is always a gotcha or two:

1. Are both drives UDMA capable? If you have one drive that is and one that isn't I think it drops to the slowest of the the two.

2. Check for BIOS, Driver, or Firmware updates for your hardware. Also, more info on the mobo and HD's you are using would help too.

3. Check your device manager like jaclaz mentioned. If you install the chipset drivers you shouldn't have to worry about it, but just to make sure check the properties of all your disk controllers and make sure it's set properly.

If you go into your BIOS, and you have it set to auto-detect, it should tell you somewhere what it found. Some BIOS will even report what it's capable of AND what it's currently set for, allowing you to easily troubleshoot if the problem lies with the BIOS or somewhere else.

It used to be that way back in the day but with newer boards you can have the drives running at different speeds. For example, I have a Pioneer DVD burner that does UDMA-4 and a Sony CD burner that does UDMA-2. They're both connected to the same channel and each doing their own respective speeds.

Thnx Now i have Ultra DMA 5 for HDD's

But how can i change MODES for DVD-RW and DVD-ROM they're both under Multi-word DMA 2 !!!

DVD-RW is a brand new NEC-4550

DVD-ROM is also new

They both support mode 5 but how can i change it ?

Thnx
