Hi, I've had an old 60GB harddisk in this computer for while.
That disk started going bad so I decided it was time to buy a new 250GB
harddisk.
I installed this new drive on the same IDE cable as the old drive, and set
the new drive as master and the old drive as slave.
I deleted the partitions from the old drive and installed Windows XP
Professional SP2 onto the new drive.
Everything was going fine until today.

Today I decided to see if perhaps reformatting the old drive could help it.
The partitioning hung a few times but completed. It left a many disk errors
in the event log showing that it's beyond fixing.

This has now set the Transfer mode for the Primary IDE controller to PIO mode.
I've now removed the old drive, but still this new drive is going slow due
to the PIO mode on that IDE controller.
Is there anyway to change it back to DMA mode?
The drive I want DMA mode back on is the main system disk.

This is standard behavior when disk errors are encountered. The system drops into PIO mode. Yes it can be reset. See this link: http://www.michna.com/kb/WxDMA.htm
