I bought it a year ago, worked fine for first six months. After that real issue came forward, with my windows 8 laptop it encrypted some files and when I wanted to copy them it said that special privelages are required by the admin of the PC, so I have to manually grant permission to each and every file stored in it to access them or to copy them from the drive to my PC.
So, I would not recommend you guys to store your critical data into this as you may loose it. Also when I have hidden my files, then when I wanted to unhide those files it again showed the error of special privelages, so this hard drive though cheap, but not at all reliable for storing your useful data.
