Hello

We (me + friend) are running Slackware 11 box as web server and file
storage.
MB: msi k9mm-v (VIA K8M800 and VT8237R Plus Chipset)
CPU Sempron 2800+ AM2
RAM 512MB
HDDs samsung sv4012H 40gb (root partition), samsung HD320LD 320gb
(one partition in /mnt/lin2)

Problem:
Slow transfer rates with samsung HD320LD (1 to 3 MB/s).

<snip>



Anyone has an idea, what can I do to get NORMAL (~30MB/s) transfer
rates?

Hi

So what does:

hdparm /dev/hdb

say? - In particular is using_dma set to "1"
If not, try hdparm -d 1 /dev/hdb

Cheers

OK, stupid of us, too much attention to line
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5
And now:
hdparm /dev/hdb

/dev/hdb:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 38913/255/63, sectors = 625142448, start = 0

And:
hdparm -d 1 /dev/hdb

/dev/hdb:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

Anoter new information:
Smaller disk (samsung 40G, master) doesn't use DMA as well:
hdparm /dev/hda

/dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 78242976, start = 0
