I edited rc.local and DMA is now turned off
everytime I load linux
I would like to know if there is some file in which
hdparm settings are stored so that DMA is turned off *permanently*
In the boot process I still get the
hda: dma_intr: status=0x51 { DriveReady
SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC
}
errors. Is there some way that I can disable
echoing of these errors? (It kinda gives me an uneasy feeling ;-)
Just for curiosity:
When I checked out /var/log/demsg I found out this
line
hda: 8452080 sectors (4327 MB) w/256KiB Cache,
CHS=526/255/63, UDMA(33)
Also the BIOS gives the following info about my
HDD:
Pri Master : 6.01 ST34311A
Ultra DMA Mode-2 , S.M.A.R.T. Capable and Status OK
It means that my HDD supports UDMA , then why I
have to disable it to keep things normal?
Does disabling it have effect on the
performance?
