Yes, but unfortunately the disk should have some place reserved for bad
blocks replacement. This is only possible during disk partitioning (pay
attention to ``bad block scan'' option). If you partition was prepared
properly, if can use bad144(8) utility as a more/less equivalent to
winblows scandisk. Also note, that if you have many bad blocks on your
disk, and/or the number of those is increasing, you should seriously
consider changing the disk.

What kind of network connection do you have? This sounds like wrong
duplex setting to me.
The output of ``ifconfig -a'' and ``netstat -r'' would be helpful.
