Hello, I have had this WD External 2TB drive for almost 6 months and everything has been working normally until today. When I got home, I looked in My Computer and it wasn't there. I then went onto forums and they said to check in the Administrator Tools Disk Management section. The drive is there, but it said that is wasn't active and needed to be assigned a letter and initialized. I got an error message saying 'Media write protected' and then didn't let me do anything more. I attempted to access the HDD on my Macbook but to no avail. It is plugged into external power, running on the latest drivers, and hasn't had any problems until now. It is also available in 'Devices and Printers', but the only options are 'eject' and 'properties'.
