DMA limited to UDMA33, non-ATA66 cable or device

I got these errors right before my server crashed, any tips?

linuxMaestro,

In this instance what it's trying to tell you is that the drive is capable of higher transfer than the 40-pin cable allows.

However the READ command timeout may be much, much more serious. Download the drive diagnostic program from the hard drive manufacturer and run it.

The bad news is that your drive is probably dying. The good news is the sooner you run the diagnostic the better chance you have of the drive still being under warranty.

I had similar messages and moved the drive to another machine and had no errors. It turns out that one of my two controllers is bad. Moving to the second controller took care of it.
