My brother bought an external hardrive that's a terabyte. It worked perfectly until I cancelled while transferring data then it went crazy. The pc and laptops began to have trouble picking the tera up and it would just disconnect by itself. Its so bad now that when you plug it in, the hardrive doesn't show by my computer but only by device and printers. The only options available are eject, create shortcut, troubleshoot and properties. We tried formatting it already but nothing seems to work.

my question is whether there is a way to fix it or if we should just get another one

Help will be appreciated
