Device not recognized during startup.
You've tried using it inside the PC and it's functioning well there. The issue seems to be with the file system not recognizing the drive, even though it appears in disk management. Moving it back to the external adapter resolves the problem. This could indicate a compatibility or driver issue with the internal setup.
Certain brands of hard drive or SSD cases enhance the physical layer before connecting to SATA/USB, sometimes using proprietary file systems that Windows can’t read on its own. This phenomenon is uncommon but has occurred several times. Could you tell me the name and model of your external USB adapter?
