We have a Dell PowerEdge T420 with a PERC H710P card. It contains Seagate ST9300605SS drives. One started showing a 'predictive failure' so we purchased another one from Amazon that was exact same make and model. We stuck it in the server and open manage would not let us add it to the RAID array. Within Open Manage i noticed 2 differences between the new one and the other 5. First it said the new one was Revision CS05 and the other 5 were Revision CS08 and under 'Certified' the new one said 'No' and the other 5 all said 'Yes'.
We called Dell and they wanted $500 for a new drive and the one we purchased was under $100 but it was same model number and brand.
So my questions are why didn't our drive work and is there a difference between the Dell drive and one purchased outside of Dell?
thanks
