Hi. My SATA HDD is recognised as a SSD and Windows 10 will not perform defragmentation on it as a result; which I appreciate. I've tried many of the prescribed procedures mentioned on forums but to no effect. I'm pretty convinced that the problem lies in the fact I have installed a SSD in my machine. Windows is recognising the correct size of my SATA HDD however and the SSD isn't showing up quite rightly as its Linux formatted. Using a third party defragmentation program exactly the same problem occurs, however I was able to defragment my C drive using it as it just warned against it and didn't prohibit me. Any suggestions would be greatly appreciated.
