Disk consistancy shows error on PowerEdge R710

Hello There,

I see 2272 ID "Uncorrectable media error" even after checking the consistancy on VD 0. However, my drives are green in VD 0. This error getting repeated for every 7 days.

I'm loaded with PERC 6/i Integrated (Embedded)

Running with 4 PH Disks

Any help is much appriciated.

Thanks

Pavan.
