Welcome to the forum :slight_smile:

Check the link in my sig (“How to check/enable DMA”), to make sure UDMA Mode is enabled for your drive :slight_smile:


Well i entred to the primary ide channel and it shows 2 devices one of them shows, DMA if avaliable and in it’s current transfer mode UltraDMA mode 5 in the second box of device 1 it shows transfer mode dma if available but in the current transfer mode it shows PIO mode and i dont have an option to change it. what do i do now?

Thanks for the fast reply


Download and run the “resetdma.vbs” file in this post, and if it finds a channel to reset to DMA Mode, it’ll do so, then ask for a reboot.

Try that, then check again to make sure nothing shows PIO Mode. :slight_smile:

(I’ve used the file before myself with no ill-effects).


Well i have tried the file and did what you said, and YES!!! it works Great just like good old times.
Thanks for the fast replys and the fast help.

I got only one last quastion just from curiosity, why did it changed to PIO mode without me doing anything? i mean how did it suddenly happen?

Thanks again.


A lot of the time, when Windows encounters x amount of disc read errors, it’ll drop that drive (in this case, your LG) into PIO Mode.

Silly, but one of Windows’ strange quirks :wink:

And you’re welcome, happy burning! :slight_smile:
