I have a 750 GB hard drive with Windows 8.1.
I recently formatted an external 256 GB SSD drive.
When I remove the SSD and look at the partitions on the HD with the "Disk Management", I see a strange "SSD (D:) 271.32 GB NTFS" partition.
What's going on? And how can I merge this partition with the "OS_Install (C:) 406.63 GB" primary partition?
