can't turn dma on [solved]

Hi,

I'm creating a new ext3 partition on a new disk, but I can't turn DMA on, I get the following error:

[14:43][root@mouse256:~]$ hdparm -d1 /dev/hda2

/dev/hda2:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Invalid argument
 using_dma    =  0 (off)

I don't boot from this disk, arch is installed on a software raid on 2 SATA disk, the SATA disks and the raid works perfectly. It's the PATA disk which is causing troubles. (/dev/hda1 is a windows/ntfs partition, /dev/hda2 is fresh ext3 partition)

okay, for the rest a description of my system:
I'm using a nforce2 motherboard (nforce2 controller for the ide disks, silicon image for the sata).
Using stock arch kernel with initcpio

Re: can't turn dma on [solved]

Check your BIOS... There should be an option somewhere in there for enabling DMA.

Re: can't turn dma on [solved]

Bios wasn't the problem (I was rather shure about this, but I did check it anyway), but when I rebooted, the problem was suddenly fixed

I found what was causing the problem:
As I do not use this drive much, I put it in sleep-mode after booting (hdparm -Y /dev/hda), this saves me energy, heath and noise.  But is seems that waking up the drive disables the dma mode...
If someone has a solution for this feel free to mention, but I can live with it for now

Re: can't turn dma on [solved]

my late response =]

First of all, /dev/hda2 is a partition, /dev/hda is the drive, so:

hdparm -d1 /dev/hda

Secondly, I suggest you use "hdparm -y" instead of "hdparm -Y" for no particular reason, heh... just try it!
