I think you might be onto something, I wouldn't say because but certainly seems related. Windows identifies the drives correctly in Windows Defrag (dfrgui.exe): Kingston SV300S37A120G SSD (C:, D:) - Solid state drive SoftPerfect RAMDisk (R:) - Unknown where Defraggler identifies them all as HDD. Using Intel Rapid Storage just for the SATA driver (Intel Chipset SATA RAID Controller, 14.8.1.1043). I believe I've seen this problem with Defraggler unable to indetify the disk types before with Windows 8.1 and now with Windows 10. Closing and reopening Defraggler never fixed it for me.

Hi, Speccy (v1.26.698) identifies one of my drives correctly (Kingston SSDNow v300) but it does incorrectly for the other two (Dataram RAMDISK and Kingston USB enclosure). 232GB Kingston SNA-DC/U USB Device (SSD) 111GB KINGSTON SV300S37A120G (SSD) 1GB KINGSTON SV300S37A120G (SSD) In Storage details it appears to show information that is specific to the SSD drive in details for the other drives - like I don't know, serial number is the first obvious one, it's the same for all. I can't seem to attach a speccy file here, so here's the published version - let me know if you need more details. http://speccy.piriform.com/results/NdcvXIyoUX8LRdhhVAFegtq Thanks, Dan
