My question deals with the PP Biz, PP Pro, and/or PP Video (boxed now) as I have all of these.

Generally, I have found the PP Biz is probably the best and most predictable of the PP series...just my opinion.  So I purchased two, 2-bay Acomdata hard drive enclosures with USB 3.0 connections and attached to my PP Biz.  I configured each 2-bay drive enclosure as a RAID 1.

All is well and both drive bays are working fine.  The PP Biz detected the empty, RAID drives without any problem.  All functions appear to work fine.

In thinking about what I planned to load on these drives, I began to wonder how Pogoplug would know if any hard drive was failing...especially my brand new RAID setup.

Does anyone know if PP has any intelligent signalling between the hard drives and itself to notify us that a hard drive was acting up?  Almost all hard drives have built-in predictive failure signals that can trigger PCs to throw up flags about the health of a hard drive but does PP?  Sure seems like it should.

I have sent an email to the hard drive enclosure maker to see if the enclosure circuitry is monitoring hard drive health and perhaps flashes the enclosure hard drive activity light or changes its color if the hard drive is having problems.

Any thoughts on this?  Thanks.
