Hard disk ran three weeks flawlessly in a Synology NAS DS215j. After the total failure. A check with a program revealed that the hard disk no production data such as serial number, firmware Betriebststunden and spent more. So for me was clear: drive defective. When packing now, to swap the hard drive through Amazon, the label of the hard disk caught my eye, one could read on the that this is a Certified Repaired HDD in this FP. So a fixed and not to be read as in the item description to a new one. An inspection of the second panel showed the same result. So be careful when INSTALLATION !!! PLEASE BEFORE THE LABEL LOOK !!! Unfortunately I missed that and now the trouble. Both plates go back !!!
Addendum dated 30.04.2015:
I've actually attempted or dared again reorder a plate. I hardly dare to say what was delivered for a plate. Of course, again a Certified Repaired HDD. From a total of 4 ordered hard drives is really just a brand-new media arrived in my ... Poor performance AMAZON or profit optimization ?? Even 2 contact recordings by mail and by telephone brought no satisfactory remedy !!! I order the plates now at Conrad.
