NOTE#1: This machine was recently "upgraded(down-graded)" from Windows 8.1 PRO x64, under this OS your software worked. After the upgrade: same issue, after doing a Clean Win10PRO install: same issue.
Software: Windows 10 PRO Build 1511_2 (64-bit) OS updated to all updates and patches, CCLeaner v5.17.5590 (64-bit)
Problem: CCLeaner (Speccy) identify the KLMN hard drives as SSD Drives even though they are SATA3 4TB Seagate Hard Drives.
As such the CCleaner tool Drive Wiper->Wipe Free Space only allows 1 pass because it incorrectly thinks that my seagate drives are Solid State Device's.
I suspect that the Win10 algorithm for drive identification has changed from Win8.1 and the "newer way" needs to be understood.
NOTE#2: Issue also occurs with: Speccy v1.29.714 (64-bit)
