Log attached. I can see the portable USB HD (Ext4) in the file manager. The USB drive I pulled the USB cable out is a 1T Backup driver. It contains everything... I pug the drive in another notebook, running the same OS. The drive does not appear. Can pulling out a USB cable damage a partition table.
