As I have many black WD drives and internal hard drives lying around , so It would be nice to be able to print a QR code with a label/ name that I can scan with my phone to see the content. Sometimes we don’t have time to plug in numerous unlabelled drives to find the right one! I know you could use a label printer which is fine if you are local. However if you keep backup drives remotely and don’t have a computer handy to plug them into then having a readable QR code would be useful and better than printing out the contents on A4 and attaching to the drive.
