[PlanetCCRMA] more disk performance problems

[jfm3]

I upgraded to planetedge and the 2.6.13 kernel for FC4.

Now, instead of seeing my disk as sda, it comes up as hda. I'm not
really sure what this means.

The timing results from hdparm seem more in line with my observed
experience now. The ioctls for improving disk performance still don't
work. I'm going to try firewire PCMCIA and/or gigbit nfs. Any ideas
appreciated.

bash> sudo hdparm /dev/hda1

/dev/hda1:
 multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 65535/16/63, sectors = 106896384, start = 63

/dev/hda1:

 using_dma    =  0 (off)

bash> sudo hdparm -t /dev/hda1

/dev/hda1:
