problem w. DMA

[paulpaul]

Okay, here it is...

Rig- Asus A7N266-VM
W2K Pro
1 WD 80 Gig JB (Boot Drive/Master)
1 WD 80 Gig BB (Slave)

Everything worked fine until I installed the 2nd drive (the BB). First I noticed performance went downhill; try to open a window and it takes up to five seconds to actually open up, programs took longer to open, etc. Went into Device Manager, and it tells me-

Drive 0

Transfer Mode DMA If Available
Current Transfer Mode PIO Mode

Drive 1

Transfer Mode DMA If Available
Current Transfer Mode Ultra DMA 5

I've gone into the BIOS, and tried every option that seemed to make sense. Does anybody have any ideas? TIA

(I've already checked the FAQs--nothing there helped)

check the jumpers first on the drives here
if thats ok you can try data lifeguard to see if the drive is set internally to run at it's proper speed.
are they showing up correctly in the bios ?
good luck

After doing what kursplat suggested and your drives check out to be ok. It might be a problem with your IDE controller. Do you have both of these harddrives on the same chain? Also on which IDE controller primary or secondary?

Thanks for the replies.

The jumpers are correct. Both hard drives are on the primary IDE connector.

I'm downloading the data lifeguard files now; I'll be back to report status soon.

I ran the WD diagnostics, and it shows the drives are okay.

Does anybody have any ideas?

good , but did you check the drives speed setting with the WD utility? you can change what DMA mode they run in , from PIO to the fastest mode they support.
also is this win XP ? if so go to device manager and expand the IDE ATA\ATAPI controllers . open the primary IDE channel properties and go to the advanced settings tab. in the transfer mode box select "DMA if available" for both devices. then repeat for secondary IDE controllers.
good luck

I ran the "Ultra ATA Manager" from the WD diagnostic disk, and told it to run both hard drives at Ultra ATA/100.. After I rebooted, I went into the device manager (I'm running Windows 2000 Pro), and it's still showing the same thing--"Transfer Mode-DMA If Available", but the "Current
Transfer Mode-PIO Mode" is what it's running, not DMA Mode.

Is there something simple (or complicated) that I'm not thinking of?

 

[kursplat]

try different ribbons ? also is the bios set to "auto detect" the drives ? if not set it to.
good luck

I would also try the one drive by it self. (The one running in PIO mode)

I would make sure that you power supply is powerful enough to handle all that. with 2 hd's and a bunch of other stuff, a 200watt power supply won't do the trick.
