in linux i found transfer errors occur unless i modify HDD setting with
hdparm i do this
hdparm -c1 -d1 /dev/hda (for my HDD) and
hdparm -c1 -d1 /dev/hdc (for my cdrom) this activates '32-bit' mode it will
not increase performance but synchronise data flow if that fails u might want
to add -X34 to that to enable 'ultra dma66' which is bullshit anyway be it
dma33/66 there is only a few percent increase in performance. In fact if i
add -X34 i get 8megs/sec instead of 12megs/sec transfer rate and more cpu
overhead for some *ing reason. I have little experience with fbsd but
would like to learn more about it and use it.-d1 enables normal dma transfer
which is the 'old' dma method yet outperforms the newer protocols. some
kernels may have this enable my default. hope it helps..ah yeah u need hdparm
installed and only works for IDE drives i think aah and u must be root to use
hdparm
