Assume that you have a computer that supports hot-swap SATA disks and is running Windows Server 2012 R2. For some system configurations, when you insert one or more drives into the computer, Windows cannot detect all the inserted drives. Therefore, you cannot see the drives in This PC or the Windows Disk Management snap-in.
This issue occurs because of a communication error that occurs between the affected drives and Windows.
To work around this issue, you can use one of the following methods.
Method 1Remove and reinsert the affected drives.
Method 2Use the Windows Disk Management snap-in tool, and then rescan for disks.
