hdparm not o.k. ?
Hi folks,
I tried to improve my settings of the harddrive. These are the original
settings:
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 16383/255/63, sectors = 195371568, start = 0
You see, dma is off. When trying to set this to on ( hdparm -d 1 /dev/hda), I
get this error:
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
could there be a bug in hdparm ? When running knoppix in 32-Bit-mode it works
fine.
These are the infos from /dev/hda:
hdparm -i /dev/hda
/dev/hda:

Could it be a bug ??? Any clue ??
