[wellylug] new hard disk problems

[Mark Signal]

Hi

I don't have a /proc/config.gz directory (I didn't compile 2.6 - I simply
did an apt-get install kernel-blah blah)

I tried another ide cable with no effect.

I appear to have fudged a solution by disabling dma in the bios and leaving
it enabled in the software. I know it shouldn't work but the error seems to
have gone and performance is markedly better - about 15% below dma activated
in bios and software whereas deactivating dma in software (hdparm) caused at
least a 50% performance hit.

I will try this drive in another box in a day or so but the present
compromise is liveable - as long as the drive doesn't splat itself :)

thanks everyone for your help

much appreciated

Mark Signal

Does the kernel report a supported IDE chipset during booting?

If it's a 2.6 kernel, check that /proc/config.gz contains the appropriate
CONFIG_BLK_DEV_ option. E.g. for my VIA-based mobo I have:

CONFIG_BLK_DEV_VIA82CXXX=y
CONFIG_BLK_DEV_IDEDMA=y

However the kernel usually doesn't let you enable DMA if it doesn't have
the correct driver - hdparm will say 'operation not permitted' or
something similar if you try to enable DMA in this case (hdparm -d 1). So
perhaps it's another problem.
