big Problem with FC 4 and SATA (hdparm error)

[Sebastian Kösters]

Hi,

i use a SATA Harddisk (Seagate 120GB) with Fedora Core 4.

Everything in the System is up to date (yum). 

When i do this: hdparm -tT /dev/sda

I get the following error:

/dev/sda:
 Timing cached reads:   1944 MB in  2.00 seconds = 971.94 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl
for device
 Timing buffered disk reads:  170 MB in  3.01 seconds =  56.51 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl
for device

Its not very fast and the error message is not so good i think.

What can i do to solve the Problem? 

I also tried FC 4 on different Mainboards with different SATA Harddisk. Same
error every time.

On FC3 with SATA there are no Problems! Downgrading is not possible. 

I hope someone can help me?!  

Thank you very much!

Sebastian
