JMicron Generic SCSI Disk Device is a common label seen in Device Manager when a computer identifies an external storage device (HDD or SSD) using a JMicron bridge controller
If the JMicron controller chip burns out entirely, the drive will stop functioning completely, regardless of software adjustments. However, the data storage drive inside the enclosure is often perfectly safe. jmicron generic scsi disk device

After adding the parameter and rebooting, the drive should work normally and the system logs will typically show a message confirming that UAS has been blacklisted for that device. What do you see in Device Manager (if any)
⚡ 3.5-inch hard drives require a dedicated external power adapter to spin up.
The is a common and usually reliable piece of hardware. If you see it, your computer is recognizing the external enclosure's controller. If you have issues, they are typically resolved by updating drivers, changing cables, or checking Disk Management.
The core of this device is rarely a native SCSI drive. Instead, it is a bridge controller—a microchip that translates the communication protocol of a storage medium (like a SATA Hard Disk Drive or an NVMe Solid State Drive) into a protocol recognizable by the host computer (usually USB).
