I had a similar problem using a new SATA-II drive with my SATA150 
controller. Once I closed the jumper to force the drive down to SATA150 
operation the problem went away. This isn't necessary on most 
drive/controller combinations (the fallback is supposed to happen 
automatically), but it was for me and sounds like it may be for you. I 
had to do a bit of searching around to confirm the jumper function 
since it's more or less undocumented for my drive (a Seagate).

Good luck,
