Unusually low disk performance

desooper

I need a little help if I may, I run a system test on my computer, Dell 2.4 1G or ram and 2 Harddrives, 1 40G for main and 1 40G for back-up, on my back-up 40 I get this message *Unusually low disk performance, this one should have a speed of 32.79 MB/s. * how do I correct this, thank you for your help,

I must say to everyone in this place you guys and gals are the best, I have used you folks here several time for help and I have always got great results for you all, so from me to all of THANKS, KEEP UP THE GREAT WORK.

Not sure. You really didnt give us anything to work with here?

How full is the "problem" drive? Try running atto on it for us real fast and post the results. You might also check in the device manager and make sure dma is enabled properly.

Ok, I am not real sure so please be patient with me, How do I check the DMA and what is otto and how do I run that, the drive only has about 6 g used. Thanks

I'll be patient. ATTO is a disk benchmark program. Check our downloads section here. I bet it's in there and if you can't find it I'll zip you down a copy in my next post.

Do you know how to get into the device manager? Look under the ide controller and under the primary and secondary ide channel go into advanced settings and see what the "current transfer mode" is set to on all four devices. (two per channel)

You mentioned you ran a system test on your machine. What system test exactly?

Ok sorry it took so long to get back to you, under the setting you asked it says (secondary ide says ultra dma mode 2, primary ide says ultra dma mode 5) i hope this is what you are referring to, thanks.

Tex

You did good so far but....On the primary ide page there is two devices. Make sure both device 0 and device 1 are both at ultra dma 5. Both the hard drives should be on the same channel. The secondary should have cdrom or dvd's on it.

OK heres a good one how do you change it. on device zero it says current transfer mode ultra dma 5 and on device 1 it says current transfer mode it says pio mode but there is no way to change it.

Tex

What does the line above it say? Does it say dma if available for both channels?

YES

Try and right click on the primary ide controller and click on uninstall and reboot. Check it again after it finds new devices on the reboot.

On Dells I have this come up all the time and I actually have better luck swapping where the ide devices plug into the motherboard and its seems to fix itself better but try this first because you don't have to open the box up for this one.

I also would like to ask, could the jumper pin on the back of the harddrive have anything to do with it. I have it set on slave, thanks.

TEX, I also did what you said and switched the cables in the tower, it now says this, Primary ide, show device 0 as ultra dma mode 2, and device 1 pio mode with them both set as dma if availiable, and the secondary ide shows them both as ultra dma mode 5 with dma if avaliable, so my question is will this effect my cd or dvd now that it is changed, thank you for all your help.
