DMA reverts to PIO mode...for various reasons.

IDE ATA and ATAPI disks use PIO mode after multiple time-out or CRC errors occur - http://support.microsoft.com/kb/817472

I've never known of a situation where it recovers back to any mode of DMA...possibly because no one would notice such unless they were continuously monitoring the drives.

Well...all I can tell you...BTW, it's not a program, it's a registry edit that must be performed by the user.

Anyway, it works for me and others.

Yeah I know but i used the word "prgram" with the actual meaning of "programming something".
