thx Flash, it looks I will go and find some certified drives
I am attempting to upgrade our hard drives from 10k to 15k, it is a 4 drive RAID5 with an H710 perc card. I replaced the first drive with a Seagate Savvio ST9300653SS drive and it has worked great, but whenever I try to replace a different drive it always comes back with a predictive drive error, that has happened on 4 different new drives.  The only difference appears to be the firmware revision on the drives, the one that works is YS07 and all failed drives are 0004. I have upgraded the perc card to the latest. Was wondering if anyone has seen this or have any suggestions?  Want to figure this out in case of a drive failure.  Thank you in advance
