Is your Hard drive running in the correct mode?

Recommended Posts

I've noticed a slow down in my computer over the last several months but really never got right down and checked it untill now.

After performing all of the recommended procedures and maintenance without any improvement.........

I decided to take a look at my hard drive in the device manager and found out that the drive was running in PIO mode rather than DMA mode, this is not good. (I'm running XP pro)

I tried to change it but the setting was grayed out.

A little research and I found This Page with a little script to fix it > resetdma.vbs.

I ran it and afterwards I was able to set my hard drive to run in ultra DMA mode 5 and the computer is back up to speed.

So one thing else to check if you have a slow computer (especially on XP) is if the drive is running in the correct mode.

Below are some links for XP, Vista and W7








Good Luck.....MrC

i wonder if there are any of those bogus scan and hostageware programs that would use this as an exploit ?

Glad to see you were able to fix the issue on your computer there MrC though certainly the issue must have been due to a fallback and not that the hardware was originally setup that way, though some techs did do it.

IDE ATA and ATAPI disks use PIO mode after multiple time-out or CRC errors occur

My memory is not what it used to be but I sure thought this issue has been around since the Windows 95 days. I know I've reset quite a few controller settings for this myself over the years.
