We had a RAID 5 drive that was going bad. We had been waiting for some time for the new drive to come in. At some point the drive was removed by the net admin to retrieve the serial number off of the drive (the drives are hot swappable so they were just pulled out). That same bad drive was placed back in the server with the power to the server still on and it mysteriously started working again.....for a a very short while. Well it has since crashed and now we cannot access our email boxes on our exchange server as I believe that drive is where the mailbox files were stored. These drives are hot swappable, but what is the impact of removing a drive in the manner that this was done and putting it back in? Will putting a new drive in at this point allow a rebuild of the array?
