I built a PC last year with a used 750GB HDD with Windows 7. I performed a clean install. A couple of months later I bought a Samsung SSD for the OS main boot drive. I used the Samsung Migration software to move the OS to the SSD, everything went smooth. I recently bought a 2T HDD because I started running out of space. I now have everything transferred over to the new HDD and would like to remove the old HDD from my PC, but I noticed the Boot, Config, Logs, Users, Windows, Perflogs, and Temp folders are on the HDD and not the SSD. I wasn't sure if this would cause boot problems if the drive was removed. Also looking at my Disk Management, I noticed Drive C, OS Drive, says System, Boot, Page File, Active, Crash Dump, Primary Partition; Drive D, the one I want to remove, says Active, Primary Partition; lastly Drive E, the new drive, only says Primary Partition. I'm not sure why I have 2 Active drives, but that second active drive is also why I don't want to remove the old drive. If anyone could guide me in the right direction for removing this drive, I would greatly appreciate it. If there is any other info that you may need, let me know and I will do my best to help. Thank you
