Changed settings using hdparm...disk read speed dropped !
 

Using the command
hdparm -Tt /dev/hda
i got the results as :
/dev/hda:
Timing buffer-cache reads: 128 MB in 1.34 seconds =91.07 MB/sec
Timing buffered disk reads: 64 MB in 17.86 seconds = 41.08 MB/sec
I then ran the command
hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda
and after that the command hdparm -Tt /dev/hda gave the following results:
/dev/hda:
Timing buffer-cache reads: 128 MB in 1.34 seconds =97.45 MB/sec
Timing buffered disk reads: 64 MB in 17.86 seconds = 28.41 MB/sec
I'm just a couple of weeks old to linux and realising that i had done something stupid, i rebooted back into windows. As is obvious, my "disk-read" had dropped to 28 from 41......so is there any way i can revert the settings as they were before i messed with them? i mean the default settings?
I'm really worried if these settings could kill my drive or smth...:confused:

Don't worry, those settings are temporary, and
gone after a reboot. The reason why your machine
got slower might be that the kernel already had
chosen the optimum DMA mode for your box,
and you might have picked a less efficient one.
