Windows 10 SSD via USB detected as HDD

My old Startech enclosure was dying on me and I replaced it with a Gembird enclosure (the only one I could get my hands on)

USB 3.0 2.5'' enclosure, black (EE2-U3S-2)

With the old enclosure, Windows identified my SSD correctly as Samsung SSD EVO 860 under Disk Drives. With the new enclosure, Windows reports it as JMicron Generic SCSI device and it thinks it is a regular Hard Drive.


CrystalDiskInfo and HDTune identify the same attached drive correctly.




Disk Defragmenting is disabled and I can manually run Trim on the SSD either via PS or defrag from CMD, so it is not a major issue, but it still bugs me.

Any recommendations?

WinVer: 10.0.18362.959

Why are you defragging a ssd

There is nothing in the OP to suggest that they are defragging the SSD. In fact, the OP is making sure Windows is not defragging it.

I would guess the interface is in the wrong mode so it doesn't pick it up. Why are you defragging a ssd

I'm not defragging the SSD. I run trim manually either via:

Optimize-Volume -DriveLetter Y -ReTrim -Verbose

or

defrag Y: /L /U /V

My SSDs connected via USB are detected as HDDs as well.

I came across that issue testing 2004 in early June.

There is also an issue where 2004 thinks an HDD is an SSD, and tries to TRIM it...and fails (of course).

Both are bugs.
