Optimize EIDE hard drives?

Iv'e used it on my local development system and it worked fine. I never tried it on my box with all my clients. As it says it can screw up some systems. As for what it does I'm not sure. I did it on my local system which has 1 domain and of course with only one domain a you won't notice a difference. I'm sure a box with 200+ clients would notice a difference.

 

I know this is an old thread , but has anybody got any more info on "Optimize EIDE Hard Drives"

 

Sure. It enables DMA mode on your disks. It was only an issue with very old disk drives. These days you should always enable it.

 

i have it enabled on all the production boxes, works fine.

 

Thanks guys for your responds :p

 

So how do you revert back to disabling it ?

 

As chirpy meantioned you always want DMA mode enabled on your disks.
The newest HD usually run DMA4 or DMA5 and having it enabled is a great performance advantage.
If you are running XP on your desktop, you can go to your device manager and check out
"IDE ATA/Atapi controllers" and see what your HDs are running

 

Does the server have to be rebooted or a particular service restarted for this to be in effect after enabling in WHM?

 

Does this work on SATA drives?

 

Yes, it does work on SATA drive.

 

It wouldn't have any effect on SATA drives. You don't need to do anything after running the script for it to work on IDE drives.

 

Why doesn't it have any effect on SATA drives?
Does someone know this?


And how do I know if I have SATA or EIDE?
