I'm running a Windows 10 64 Bit OS (version 21H1). My C drive is the only drive that is a SSD drive (Transcend 500 Gig), but the rest of my internal and external hard drives are conventional types (1 through 5 TB's).
When running Defraggler, it shows all of my drives as being SSD and warns me that I could do harm by defragging my drives. Why are my conventional hard drives (Western Digital and Seagate) being identified as SSD drives?
What could be the reasons? Is there a setting I can change to correct this?
Interesting - just ran Speccy and it also shows the drives as being SSD's also. But windows shows the drives (other than my C drive SSD) as conventional USB or SCSI devices.
Defraggler (2.22.995 (64 bit)) - I use four WD 4Tb HDDs, (3 x Bloody great big boxes, and 1 little box, that click and hum all the time) and the application tells me the 3 of them as SSD and one is an HDD. They are all USB connection, SATA/600 at 54000 RPM, (Don't think SSD spins up or down!)
How do I stop Defraggler telling that I'll degrade them if I Defrag them... ?
So the bottom line - experienced by many of us - is that both Speccy and Defraggler are erroneously recognizing conventional hard drives as SSD drives. Sounds like a major bug here - especially when windows recognizes them all properly.
seagate have perhaps much larger drive-cache as the standard (32 or 64 mb). i dont think that defraggler or speccy (long time ago for updates) can idendifying this as hdd with such a great cache.
if you have the exact type/name? or take a look at the homepages -> there are listed the drives and the inbuild cache-sizes
All of their software has issues detecting the disk type correctly, even CCleaner has the issue. At least with CCleaner it's regularly updated so when updating it that will sometimes mysteriously fix the issue until it happens again with another version.
Windows itself can get the detection of disks incorrect, and it's sometimes down to how they're formatted as in the file system - for example I've no issue formatting a USB Flash Drive (32GB) and tricking Windows 10 into thinking it's a Hard Disk Drive.
