hdparm

[faz faz]

Hi to all!
I have an acer travelmate 800lci with sarge installed, and i want to know if my ide hdd settings are right..
the problem is that when i watch some divx the stream hangs sometimes and the audio too..
i paste some info:

Model Number:       IC25N040ATMR04-0

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  3 (32-bit w/sync)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 16383/255/63, sectors = 78140160, start = 0



DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5

udma5 should be very good, but when i make hdparm -tT /dev/hda i got these bad statistics

/dev/hda:
 Timing cached reads:   1588 MB in  2.00 seconds = 795.54 MB/sec
 Timing buffered disk reads:   10 MB in  4.05 seconds =   2.47 MB/sec

So, i don't really know why my hdd is so poorly performing..
(i have kernel 2.6.14.4 suspend2 patch)

Thank you
Bye
