DL320s with non-HP SATA disks (Seagate 7200.11)

[GaryF]

We installed Barracuda 750GB and 1500GB SATA disks (for cost and density reasons) in a DL320s + P400 running Win2003. This is the first and only time we've gone with non-HP drives, but the largest available HP-branded SATA was a 1TB at >> $600 (the 1.5TB drives were < $200). Anyway, the 750s are in a RAID1, the 1.5 disks in a RAID6. They all ran fine for a few months, then one morning I got *many* event log entries reporting unrecoverable read errors on a controller consistency check (or surface scan). This kind of snowballed, as the controller marked down the drives, then eventually the volumes. I was able to re-enable the volume(s) with the ACU and pull the data off, but have otherwise pulled them from the machine. Has anyone else experienced success or failure using this controller/drive combo? Obviously, with the recent Seagate trouble, I'll update the HDD firmware (though these disks did not "brick" as seems to be the notorious failure mode). The 750s are using firmware SD15, while the 1.5s are SD17. All the HP is latest.
Thanks!!
