help with hdparm
...O_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 15733/16/63, sectors = 15858864, start = 0
when I do "hdparm -d1 /dev/dhc" I get
/dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
I get operation not permitted.
How do I enable DMA mode for this device?

Bug report - yours or mine?
...although the speeds are similar.
Is this dodgy hardware, kernel, or what? Where should I look for a fix?

[root@genius /root]# hdparm -d1 /dev/hdb
/dev/hdb:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
The system is Mandrake 8.0.

hdparm strangeness
...al (I think) Seagate
80gig SATA drives. I tried to copy data from the first drive (sda) to
the second drive (sdc) and was only getting about 1.7megs/sec. So I
figured DMA was off. And this is what happened when I typed "hdparm -d1
/dev/hdc":
/dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
Any suggestions? I've never had this type of problem before.
Thanks,

DMA mode

using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)

...but I can't set it on:
# hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
...which I think is because the IDE controller isn't really
recognized, or is pretending to be a SATA controller:
