I have an external hard drive but cannot access the information on it. I tried to access via Ubuntu and Windows, but both show the same message: device "0 megabytes".
I tried to mount the device but it shows this message:
mount:only root user can mount /dev/sdb on /mnt/usb-JMicron_USB_to_ATA_ATAPI_Bridge_152D203380B6-0:0
sudo
in front of your mount command?
