DMA will not damage the drive.
In my experience a drive tends to fail either when it is very new, or
when it is very old. I have had a drive fail in 4 hours after being
installed. I have had it happen after 2 weeks, and I have had it happen
after 6 or 7 years sometimes. I had a 13 year old scsi drive die on me
recently, which I certainly won't complain about. :)

You could probably even do an ide=nodma kernel option (unless the
modular ide system ignores that). It certainly looks a lot like the
errors I had on a machine last friday just before the drive totally died
on me. :( Get the important data off there ASAP.
It is very unlikely turning off dma will solve anything or even help.
It will make acessing the drive much slower though.
