One of the 8 drives in the array failed. This is the third drive to fail in the last 6 months. All Seagate 7200.11 1TB drives. The other times I change out the failed drive and the array rebuilds fine. This time I replaced the drive. Its starts to rebuild but constantly reports bad blocks about 10 of them. After that it starts reporting bad stripes as well. Once its done rebuilding there is still an exclamation mark on the controller icon. I did a rebuild and verify and same thing.. bad blocks and bad stripes. After this still exclamation mark but no more errors reported. Is the new drive I put in bad? Should I try to remove it and put in another and have it rebuild again? The data seems to be fine although I haven't verify all 4TB of it. Should I run a chkdsk from windows?
