Disk Replacement

I'm running an OWC Thunderbay 4. One of the drives had a "disk failure predicted", so I replaced it and rebuilt the array. I am still getting the "disk failure predicted". I'm assuming that its still thinking its the previous drive. Is there a way to re-scan the drive or some way to clear the error? I tried clearing I/O and Error Counters but that didn't do anything. I also ran a second Validation but its still showing the disk failure predicted. I guess it could be possible that this drive could be failing too, but I wanted to get some feedback. Any suggestions would be greatly appreciated.
