As Russell mentioned, your USB adapter is disconnecting, that is why /dev/sdg is AWOL. Are you sure you are plugging into a the correct port? Bad USB adapter? PRO TIP: Connect *JUST* the USB adapter - no drive - and check dmesg. It should not disconnect (just show 'media removed') and the USB adapter *MUST* be listed in 'lsusb'. For example, for my 3.0 USB adapter # dmesg [603063.361794] usb 4-4: USB disconnect, device number 2 [603067.792014] usb 4-4: new SuperSpeed USB device number 3 using xhci_hcd [603067.804645] usb 4-4: New USB device found, idVendor=174c, idProduct=5106, bcdDevice= 0.01 [603067.804650] usb 4-4: New USB device strings: Mfr=2, Product=3, SerialNumber=1 [603067.804652] usb 4-4: Product: AS2105 [603067.804654] usb 4-4: Manufacturer: ASMedia [603067.804656] usb 4-4: SerialNumber: 00000000000000000000 [603067.805029] usb-storage 4-4:1.0: USB Mass Storage device detected [603067.805311] scsi host10: usb-storage 4-4:1.0 [603068.822185] scsi 10:0:0:0: Direct-Access ASMT 2105 0 PQ: 0 ANSI: 5 [603068.822690] sd 10:0:0:0: [sdf] Media removed, stopped polling [603068.823478] sd 10:0:0:0: [sdf] Attached SCSI removable disk and $ lsusb ...
