[gentoo-user] Problem with hdparm and SATA-controller

[Marc Blumentritt]

Hi,

I want to optimize the "sound output" of my shiny new sata disc, but I
have some problems to set hdparm options. My options look like this:

# SATA Disk
sda_args="-d1 -c1 -u1 -A1 -S6 -M128 -B1"

I don't know, if I really want it to spin down, since my system is
running on it. But that's not the real problem. I think I have a problem
with my sata driver, since the output of hdparm looks like this:

hive linux # hdparm /dev/sda

/dev/sda:
 IO_support    =  0 (default 16-bit)
 readonly      =  0 (off)
 readahead     = 256 (on)
 geometry      = 30394/255/63, sectors = 488281250, start = 0
hive linux # hdparm -i /dev/sda

/dev/sda:

 Model=SAMSUNG SP2504C                         , FwRev=VT100-52,
SerialNo=      S0WRJ1PP510578

 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455
 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}

 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5
 AdvancedPM=no WriteCache=enabled
 Drive conforms to: unknown:  ATA/ATAPI-1,2,3,4,5,6,7

 * signifies the current active mode


This was AFTER starting hdparm with the options given above. I also have
these error messages after starting hdparm:

* Running hdparm on /dev/sda ...
 HDIO_SET_32BIT failed: Invalid argument
 HDIO_SET_UNMASKINTR failed: Inappropriate ioctl for device
 HDIO_SET_DMA failed: Inappropriate ioctl for device
 HDIO_DRIVE_CMD failed: Input/output error


This the output of lspci:

(Motherboard is an ASUS P5K)

What is the correct driver for my SATA devices? And what is wrong with
the hdparm output?

Thanks for any help and hints,
Marc
