Important commands:

# Get related infos for flashing (sector size, start and end addresses)
sudo fdisk -l /dev/sdc

# Alternative for better regex actions:
sudo sfdisk -d /dev/sdc

# Copy image to storage
sudo dd if=/dev/sdb of=/media/auvidea/500GB-HD-USB3.0/image.bin conv=noerror,sync status=progress

# write raw image
sudo dd if=/media/auvidea/500GB-HD-USB3.0/image.bin of=/dev/sdb conv=noerror,sync status=progress

# get device info, "/dev/sdX" is your device here
lsblk -l -o name,size,maj:min "/dev/sdb" --json

# connected sdx
readlink -f /dev/disk/by-path/pci-*-usb-*-scsi-0:0:0:0

# Get additionally information
udevadm info /dev/sda

# Results for Bus 4, Port 4 -> 2 -> 1
