Hi,
I know this may be a silly question since it probably a hardware limitation,
but I'm running F7 and would like to know what I can do to increase the hard
drive seek time, if anything.
I have a pretty new SATA drive at 3GB/sec and it seems to have to seek longer
than I'd expect.
It's running with DMA4, AHCI, etc.
The rest is an ASUS MB with a Core 2 Duo 6400 @ 2.4 Mhz & 2GB Ram @ 800Mhz.
Are there any setting from the standard that by help?
here's the hdparm output
[root@localhost ~]# hdparm -tT /dev/sda
