Re: XP Won't Use DMA With My Hard Drive



Fitz - thanks for the attention you give to my problem!
Peter - my first blog. The language blew me away. I'll never learn to write
like that. Thanks.
Under NVDIA nForce Parallel ATA Controller Properties I show:
General: Device type: IDE ATA/ATAPI controllers,
Manufacturer NVIDIA Corporation
Location: PCI bus 0, device 6, function 0
Primary Channel:
Master Drive - 1st hard drive
Transfer Mode - Ultra DMA6 - Ultra 133
Let BIOS select transfer mode - not selected
Enable read caching - enabled
Enable write caching - selected
Slave Dirve: 2nd hard drive
Transfer mode Ultra DMA 5 - Ultra 100
the other selection as above

Secondary Channel:
Mater Drive - DVD RAM
Transfer mode - Ultra DMA 2 - Ultra 33
Slave Drive - Mitsumi CD/RW
Transfer mode - Multiword DMA 2

All seclection below "transfer mode" unavailable except for BIOS which is
deselected in both cases.

I did not follow up on your other suggestions. I want to wait until I hear
what you have to say?

Ok- Take a look in Device Manager (Control Panel>System>Hardware>Device
Manager) and open up IDE ATA/ATAPI Devices. Look under PATA controllers
(listed separate from SATA controller) double click or right click and
open "Properties". It should list the Primary and Secondary channels, the
devices attached to each and the transfer mode. Are they listed correctly
(hard drives on Primary (Master and Slave) and CD/DVD on Secondary (Master
and Slave)? What is the transfer mode (should be DMA for all four). If
it's PIO, then you need to re-enable DMA, using the procedure in my
original post (the link to the website). If the CD/DVD devices are not
listed, then open CD/DVD Drives (in Device Manager) and see if they are
listed as SCSI devices. If so, reinstall the IDE driver (IDE ATA/ATAPI
Controllers>Right click>Update Driver and follow onscreen instructions).
To check the jumpers, look at the back of the CD/DVD drives. There should
be a map of how the jumper is set for the different modes (CS, M and S).
Make sure that they are not both set as Master. If you have the manuals
for the drives,it should show jumper positions also. Most of the time,
it's hard to see the guide on the device itself and you have to physically
remove it to see them. The manufacturer website may have the jumper
setting guide and would be a good place to look. If the drives are both
set in CS mode, you might try setting one as Master and one as Slave and
see if that works. You could also try disconnecting on drive, and restart
the computer and see if the other drive went to DMA mode or if you can
change it to DMA when it's not sharing a Channel.

I don't know what you meant by "His reaction to it was negative"...if he
built the system a month ago, and you haven't made any changes, then the
transfer mode for IDE CD/DVD should be DMA. If it not, then there is a
problem and he should fix it. Sometimes, when a SATA/RAID driver is
installed, an IDE device will show up as a SCSI (SATA) device, an no
transfer mode is listed. I've had this happen and reinstalling the IDE
driver corrects it. It didn't actually affect the drive/computer
performance and NERO certainly didn't give a warning about it.

Good Luck,
Fitz
