I've seen several replies from moderators attribute this to CCleaner getting drive type from Windows and in the case of my system that's not the case. Windows is correctly identifying the plugged in (external) USB drive as HDD, yet CCleaner is identifying it as SSD. Now, once upon a time I have plugged in an SSD via USB, and perhaps some registry item that CCleaner is errantly looking at indicates wrong drive type.
Developers should dynamically check drive and not depend on any old/stale information. It's unacceptable that this CCleaner issue hasn't been fixed in years now!
Note that I'm fine with single pass on a newer high capacity (very small geometry) drive, but I'm talking about old drives in the 20-80 GB range where drive geometry can still allow forensic recovery if not properly erased with multiple passes.
Below is a capture from Windows Defrag tool that correctly shows drive type...Note how my Drive "Z" is correctly identified as Hard Disk Drive. Then in the follow-up screenshot from CCleaner (v5.82.8950...latest as of 7/1/21) drive "Z" is incorrectly identified as SSD. No folks, not coming from Windows...unless developers calling wrong API...and no, this is not some hybrid drive with both NAND flash and rotating media...it's a plain old Seagate Barracuda 7200.7 HDD.
Please fix this once and for all!
...and here you go...CCleaner again mis-identifies as SSD.
