I disconnect even after all those years where I couldn't, yet had no damage.

I can't get rid of the wired network. wireless isn't fast enough for 
large file transfers and I do a lot of photography with typically 8 to 
10 terabytes on each of 4 computers.  Unfortunately even a gigabit 
network is slow when talking this much data.  OTOH  I've reached the 
point where the computers I/O is now the limiting factor.

I have 3, 130' runs to the shop (two used, one spare), 2 roughly 12' 
runs to the two in here and 1 of about 30 feet to my wife's computer,

We do have wireless for the lap tops and net books.
