Should now so the USB controller get broken (is relatively common for external hard drives), break out or the USB port, you can no longer access his data. Other External hard drives would you simply plug in another case.
Although I've got a new warranty but my data is gone. Of the more important data I had fortunately a backup.
Sure, you can also go the hard disk itself broken, then the data with other external hard drives are also gone, but if only the USB controller is defective you lose not equal its data with others.
An alternative would be for example to buy a WD Notebook Hard Drive and to put in a USB 3.0 enclosure.
