Sata Harddisk on Openna very slow

The problems could range from:

BIOS-settings
Defective Controller
Bad Harddrive

How are you measuring the 1M/s ???  Which tool?  What kind of SATA HDD - size / Manufacturer / age ???

To check the above:

BIOS-settings:  set everything temporarily back to default settings (take note of current setting before doing this.

Defective controller:  Connect a different SATA-Drive to see what the performance is like, as well as switching out the cables.

Bad Harddrive:  Connect the HDD to another computer to see performance changes.

Hope this helps.

It could be caused by the DMA-PIO setting. Make sure that your hard disk is set to PIO mode.

Saygin_Yilmaz:  DMA-PIO setting for SATA HDD???  That only affects the ATA/ATAPI controller!  Read here :-)

gwu929:  check cables to make sure they are not bent and that they are properly seated.  I read another article about problems arising with some WD HDDs.  Is that what you have?  Did you try out my previous suggestions yet?  Let us know any results.

I think I finally know what is the problem with the disk drivers now.
Basically the 2.4.28-30 kernels disabled piix combined mode support. I need to
apply the newest patch from the author to enable that.

Thanks all!

Glad to help :-)
