Not a platter but the whole HDD.
Never underestimate the bandwidth of taking one HDD from one machine to the other vs. copying its contents through the pipe of a 1 GBps network. That's what I was trying to avoid - the copying across the network which is considerably time consuming.
My use case is that I want to move a bunch of new files from one machine to the other just by taking the HDD from the 1st machine and connecting it to the 2nd machine. It would be nice if the pools are named the same on the different machines that it would automagically add the HDD to the pool on the 2nd machine. Please note that I do not use balancing in my systems. All I'm trying to avoid is the copying through the network.
But, alas, I guess Drivepool is not for this particular use, which I understand.
Thanks for your help Umfriend.
