WARNING - WRITE_DMA UDMA ICRC error

[César Amaya]

hello list!

I´m having a trouble with a hard disk, I´m getting this warning:

kernel: ad2: WARNING - WRITE_DMA UDMA ICRC error (retrying request)  
LBA=38059135

I read that it could be a IDE cable problem, that the cable does not 
support UDMA speed >= 66

If it wasn´t the cable where the problem is, how can I set the drive 
UDMA speed to  UDMA66 at boot time to make it permanent?

I have a FreeBSD 6.1 system and ExcelStor j880 hard disk.

Could you help me, please?
Thanks.
