Driver of motherboard (MSI 845PE)

Gleb · 11-11-2006, 02:52 PM

There's problem with my HDD (Seagate Barracuda 7200, 80Gb): maximum speed (measured with "hdparmm -t") is about 26-27 Mb/sec. Maybe, the reason is wrong work with motherboard and its controller. So, the questions are: what's the situation with my motherboard in Linux (I use Suse 10.1 with kernel 2.6.16.13-4-default) and how to set up it?
P.S. Maybe I also must refresh BIOS flash/

Post the print of 'hdparm -v /dev/hda'.

Keep in mind that hdparm is not a benchmark tool. There are many variables that changes the throughput of a hard drive.

Seagate IDE/SATA hard drives are slow (high latency) and should not be used as an OS drive. I suggest using Western Digital or Hitachi hard drives because they make low latency hard drives.

BTW, in Linux there is no such thing as driver. It is called module. There are no modules for chipsets because the software is built into the kernel.

Code:

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 1024 (on)
 geometry     = 16383/255/63, sectors = 156301488, start = 0

All the changes in the settings practically have no effect on productivity of HDD. The main thing is that it's impossible to set UDMA mode with higher productivity then udma2.

Yes, but I was told that on Seagates normal speed is about 38 MB/sec.

May kernel recompiling help me there?
