I ran across a very similar problem a while back. What I found was that the mobo had the usual 2 IDE ports, however only one of them was for use with the ULTRA specifications (seems like the mobo connector was blue or red). Anyway. whoever assembled the computer actually had the hard drive cable attached to IDE 2 which apparently was not rated for ULTRA. Once I swapped the connection the error disappeared and performance improved.
Just thought I'd throw that out at you.
Good luck.
