Hello, GalaxyTechService. This may not be as complicated as it sounds, actually. There is a wizard you can use to put the disk back into the raid set. Right click on the virtual disk affected, and select the "Replace Physical Disk" and use the wizard that pops up. In the top field will be the 'Missing disks', and in the lower field will be options available to replace them. Then just follow the steps.  Let me know how that goes.
We have a Dell MD3220.  one of the wrong drives was pulled out by a end user trying to swap a failed drive. Then after the correct drive was replaced the old drive was put back into the correct slot. now we have one hot spare(enclosure 0, slot 23) subbing for another hot spare(enclosure 2, slot 22). The hot spare that is being subbed for has been replaced by two new drives now and the hot spare in use has still not gone away. any suggestions on what to do next?
