3.05 MB is even less than what I'm used to see with most drives and *PIO 4* !
Is there any ide message in /var/log/messages ?
I see you use hdparm to setup the drive/controller settings. I advise you to let the kernel autotune the transfer modes by itself.
Could you send us : - the exact kernel version, - your kernel compilation config file, - any kernel parameters provided, - the content of /var/log/dmesg, - the output of `lspci -vvxxx`, - the ouput of `cat /proc/ide/sis`
