I'm have WHS2011 with 4 drives in the pool. However 1 of my drives a 3Tb with 2 partitions is missing the front 2Tb partition while the back 1Tb is still in the pool. I can not add it back into the pool. Ran a CHKDSK with only 3 error that were repaired. I'm looking for any advice to try and get back into the pool without data lose.
