It basically means the drive has failed as it cannot be mounted.
While using off the shelf (WC, Lacie, Seagate) drives are attractive due to their low price their enclosure quality leave a lot to be desired. Going forward what most experienced users recommend the OWC Mercury Elite Pro line due to their reasonable cost, high reliability rate, ease of repair (yours is likely a throw away), and the great service from the vendor. You can find them at https://eshop.macsales.com/shop/owc-mercury-elite-pro. If you are outside the USA, no problem they have distributors all over the world.
