this solved problem for me and some guy from mailing list, so i think
it was not due to bad cable...here is the solution:
to the /boot/loader.conf add line: hw.ata.ata_dma=0
to the /etc/rc.local add line: atacontrol mode 0 udma2 udma2
and restart your system.
can somebody competent explain me, why this solved the problem? are
these errors due to some problems with ata driver or udma pproblem?
