Cable is greater than 20 inches (standard of UDMA support is 18 inches), this is the upper limit that I have made imperical tests with to test the 18 inch rule.
For a simple test, call "hdparm -X34 /dev/hda" and put the drive into DMA mode 2, after booting. Do some work and you should not see these errors. Then call "hdparm -X66 /dev/hda" and put the drive into UDMA mode 2, and then the errors should return, if it is a cable length problem.
