For some reason i don't think that it is bad sectors, but a bad configuration.
When i started the bad144 i got a huge number of errors, and the disk has
never before coursed any problems. It used to be in an WinNT machine of mine.
What i get is this.
/kernel: (da0:ncr0:0:0:0): READ(06). CDB: 8 6 9c e2 1 0
/kernel: (da0:ncr0:0:0:0): READ(06). CDB: 8 6 9c e2 1 0
/kernel: (da0:ncr0:0:0:0): MEDIUM ERROR info:69ce2 csi:0,a5,1,14 asc:11,0
/kernel: (da0:ncr0:0:0:0): MEDIUM ERROR info:69ce2 csi:0,a5,1,14 asc:11,0
/kernel: (da0:ncr0:0:0:0): Unrecovered read error sks:8,0,80
/kernel: (da0:ncr0:0:0:0): Unrecovered read error sks:8,0,80
each error message is repeated, and all three of them every time.
The addresses changes of course. Is there any other way to investigate this
problem?

It's a 10Mbps network. Both machines are attached to the same hub witch
also connects the network to a 384Kbps aDSL modem.
We have 16 static ip addresses, but in the output from the ifconfig is a
broadcast to 216.99.203.143.
That ip is not within then range of our sub net. Could that be it?
