A laptop, you say ? And network reception is jamming while
there is high disk-write activity ?

/sbin/hdparam -v /dev/hda

/dev/hda:
multcount = 16 (on)
I/O support = 1 (32-bit) <----- ??
unmaskirq = 1 (on) <----- ??
using_dma = 1 (on) <----- ??
keepsettings = 1 (on) <----- ??
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
