USB 드라이브가 lsusb 및 dmesg에 표시되지만 lsblk 또는 fdisk에는 표시되지 않음

이 USB 드라이브가 있는데 수리하려고 합니다. 삽입하면 dmesg에 다음이 표시됩니다.

[83630.997986] usb 1-10: new high-speed USB device number 12 using xhci_hcd

sudo lsusb는 다음을 제공합니다(버스 001 장치 012는 USB 드라이브입니다).

이는 드라이브가 작동하지 않으며 드라이브에 저장된 데이터가 복구될 수 없다는 의미입니까? 아니면 그렇게 되도록 하는 방법이 있나요?

미리 감사드립니다
