I have an older laptop (HP ze4400 series) with a PATA hard drive.
When I check hdparm -T /dev/sda in Fedora 7 or 8, it shows me
performance of ~180MB/sec
When I use a boot CD (gparted/clonezilla) to check the speed (by the
way, it uses the old style /dev/hdc, instead) - it tells me the
performance is upward of 400MB/sec
The buffered speed seems about the same in either case at ~30MB/sec.
(I've tried enabling/disabling various settings via hdparm, while in
boot CD mode)
Why is this happening and is there a way to fix it (without reverting
to /dev/hdc)?
*bump* since I got no replies from last time
Just ran another test: in F8, I get 123MB/s on cached reads, 28.55MB on
buffered reads. When booted into Knoppix 5.1.0, cached reads say
210MB/s, and buffered reads fluctuate between 15MB/s and 20MB/s.
Thanks in advance for any info
P.S yes, old message should've said /dev/hda, not /dev/hdc :)
