Expected behaviour for bad drive sectors?

[Martin Foster]

I was curious as to what would be the expected behaviour when attempting 
to read or write to a bad sector on a drive?

I have been encountering hard lock-ups on an MacPPC 4.7 machine when 
running rsync against another host.  Whenever it reaches a certain file 
the system would lock up to anything that requires access to the 
physical drive.  Hence pf would work, but Apache, future logins or even 
attempts to cancel the rsync process would simply do nothing.

Hence is this an expected behaviour, or should I be looking at something 
else?  And if it is a bad sector, any way to map and disable them for use?

Thanks.
