Windows 10: Windows cannot recognize and access external ssd disk

Hello,

Windows cannot recognize the disk, writes that it does not have access to it and does not appear in the disk manager. However, the external drive is recognized by another Windows computer and is operating normally. Therefore, the problem is somewhere in my computer or more precisely in its operating system.

How can I solve it? And no, it's not an option not to use this drive.

External SSD not recognized as SSD in Windows 10

Hello community!

(this topic applies to Windows 10 and Windows 8.1 equally)

my question concerns an external 240GB SSD drive connected to my laptop via an USB 3.0 port. The SSD works fine, but when using the "Optimize Drives" utility, the drive is listed as "Hard Disk Drive" under media type. As stated by almost all SSD manufacturers,
standard defragmentation on a SSD can actually harm the SSD and over time reduce performance and life-cycle. A test revealed that the optimization for the external SSD is actually performed like on a regular HDD and the TRIM command is not used. This would
also indicate that the regular TRIM commands issued by Windows are not applied to the external SSD drive either. Short of turning off automatic optimization, is there a way to tell Windows that this is an SSD drive and to treat it as such (regardless of
the information provided by the disk- or case-controller) ?

See also picture attached -

Drive C: is a SanDisk SDSSDXP480GR131 SSD drive built in the laptop and recognized properly as an SSD.


Drive F: is Lite-On LMT-256M6M SSD drive attached via one of the USB3.0 ports and classified as regular HDD.

I have tried changing drive letters not able to do that. This happened when I disconnected an hdmi cable, The external drive stopped responded at that point so I unplugged it but when In plugged it back it is not being recognized. I can feel the disk spinning
so it is working. Any suggestions? Thanks in advance
