LM7.2 hard drive optimization

[eXtremist]

When I installed LM 7.2, it asked me if I wanted to do some hard drive optimizations. Knowing my drive supports 32 bit I/O and DMA, I checked this.

BUT, when I go to the console and type hdparm /dev/hda, it tells me that the drive is operating under 16 bit IO and no DMA. So, where did these 'optimizations' go..? Why aren't they happening?

hdparm -Tt /dev/hda tells me my hard drive is going at about 3.5 MB/sec. That's not very optimized. I added hdparm to my rc.local file, but I'm still confused about what LM thinks an optimization is.

Greetings,

Now that you added hdparm to your rc.local is it working the way it's supposed to?
I have a similar problem. 2 HD's, and optimizations turned on for both of them, however, hda is going 19.8 MB/s which is pretty good, I think, but hdb only goes 8.x MB/s. But if I do the hdparm thing on the command line it goes up to 19.x MB/s. Yes optimizations are turned on for BOTH of them in the init scripts!
Does anyone know why this is happening? It's LM 7.1, btw.

Well.. When I went to the LM homepage and looked up any info I could get on the so-called 'hard drive optimization'.. Here's what I found..

The optimizations are supposed to be put in the file /etc/rc.d/init.d/mandrake_everytime yet when I check this file, there's nothing about hdparm in there.. Was it left out or something?

Yes, in LM 7.1 it's where the optimizations are. Maybe there's a bug in LM 7.2 installation?
