I spent a weekend trying to make the problem go away. Since I had seen the problem on two different systems, two different manufacturers and two different chipsets, I figured the only thing in common was Linux. Both drives were brand new. I started making the system simpler and simpler, removing things one at a time. I disabled all the BIOS features such as readahead, etc. Used hdparms to take away all features that might improve performance. Finally go to the motherboard BIOS setting for IO modes. It was set to auto and was detecting PIO mode 4. I manually set it to PIO mode 3 in the BIOS and the problems went away on both systems.
In other words, I THINK I told the controller chip on the board not to use anything higher than PIO mode 3.
It worked for me. YMMV.
