UDMA Problem

  blackfazer 09:32 11 Jul 03

My system

Asus A7S333 MoBo, Primary IDE has 20gb HD and Liteon 52x CD-R, secondary IDE has 120gb HD and Pioneer A05 DVD burner. AMD 2400+ CPU, 512mb PC2100 RAM. Windows XP Pro.

My Problem

The secondary IDE is very slow and I can only configure it to use PIO. It's set on Auto in the bios so I don't really have much control over it.

Any ideas how I can speed things up, please ?

The MoBo manual states that both IDE connections are UDMA 100 and that I need to use 80-pin cables. This I am doing.

Try it with the DVD disconnected - Optical and magnetic drives do not always co-exist happily on the same IDE channel, and it can vary from make to make.

Have you loaded the motherboard chipset drivers - if not then you should - they may change matters.

Thanx for the imput.

I've put both HDs on the primary channel and the CD and DVD burner on the secondary channel.

The slave HD is now very fast but both the burners are now burning slower than they should be.

Sisoft Sandra reports only one ATA/Atapi controller. Is this normal ?

Therre doesn't seem to be any support for UDMA on the secondary IDE channel. I'm baffled. :-(

Have a look in the BIOS and see if the secondary IDE channel is configured correctly.

Also try the CD-writer (the one that was on the primary, originally) on it's own, in case of a problem on the DVD drive.

AND - try another IDE cable (or swap them around if all else fails

OR - I have seen some optical drives that didn't like 80 wire cables - try it with a 40 wire instead.

Thanx again.

I've tried all your suggestions and nothing has worked. I've decided that the easiest thing for me to do is install a PCI IDE card and see if that solves the problem.

I've not had a problem like this before. I've only had this computer running for about six weeks, I built it myself, but it's only since I've upgraded to faster hardware that I've noticed the problem. Everything was fine on my old system.

Oh well...:-/

Thanx again for you time and input, it's appreciated.

Go to Device Manager and set the DVD to DMA, you may have probs if you do it with CDRW but you can try it

I have the same problem on a nforce board with xp,my secondary ide is also PIO,reading about this its set by xp(my bios is also on auto)as you may get errors in dma,I have tried everything to enable dma,you dont say what chipset,I also have a computer with a intel chipset which has no problems with dma on all IDE's but the nvidia chipset even though higher spec wont enable it for the secondary channel.

I recently upgraded my bios (7 versions out of date LOL) and many were to address hard drive speed problems in XP. The system seems a lot more stable and faster now. Mine is an intel too.

The chipset is SIS 745.

Thanx to everyone for thier thoughts.
