suspecious ide hdparm results with 2.4.1 (and a minor capacity question)

[CaT <cat@zip.com.au>]

well I got my ATA100 IBM HD and my Promise ATA100 card to go with it and
shoved them into my ultrafast VX MB (cough). I then ran hdparm
to see how fast the sucker could get and got this:

[02:02:24] root@gozer:/root>> free; hdparm -tT /dev/hde; free
             total       used       free     shared    buffers     cached
Mem:         94520      91760       2760          0      63272       6780
-/+ buffers/cache:      21708      72812
Swap:       266032          4     266028

/dev/hde:
 Timing buffer-cache reads:   128 MB in  3.54 seconds = 36.16 MB/sec
 Timing buffered disk reads:  64 MB in  3.13 seconds = 20.45 MB/sec
Hmm.. suspicious results: probably not enough free memory for a proper test.
             total       used       free     shared    buffers     cached
Mem:         94520      91828       2692          0      63608       6524
-/+ buffers/cache:      21696      72824
Swap:       266032         12     266020

Now... that suspicious results note makes me ponder that the results
aren't for real but... if they are, gawddamn. That's more then I hoped
for. 8)

Also, as an aside question, I want to get as much capacity out of this
HD as possible, back and windows compatability be damned. It's currently
in LBA mode (I believe) and that, to my knowledge, wastes the most space.
Is there anything I can do to get more of my HD back for use?
