[labnetwork] HDD Best Practice

[Demis D. John]

We have also found that keeping a cloned HDD *outside* the computer chassis is very important.  

Once a tool has been set up satisfactorily, we then take the tool down, clone the HDD onto a similar one (using external HDD cloners), and then keep the clone in a separate cabinet (anti-static etc).

In addition, we have all user recipes, software folders backed up from the live tool computer to our network storage. 

So for restore - we can swap the cloned HDD back into the computer, 
And then copy the backed up network files to the computer. 

We had a power glitch result in damaging Both HDD’s (including raid backup) within our ASML computer)!

Our setup where we just have a single working drive and a spare backup clone has been more successful. We are planning to move away from Raid Mirror. Anyone has expertise/experience here they can share?
