dma_int errors

[Coen De Roover <cderoove@vub.ac.be>]

Hello, 

I'm frequently getting these errors. 
Is there anything that can be done about it and is it potentially
dangerous ?

Nov 23 14:03:00 pinky kernel: hda: dma_intr: status=0x51 { DriveReady
SeekComplete Error }
Nov 23 14:03:00 pinky kernel: hda: dma_intr: error=0x84 { DriveStatusError
BadCRC }

Thanks in advance,
Coen De Roover
