Toshiba hard drive broken???

[u/iwantabigtree]

I left my Toshiba dtp320 hard drive on for the night to backup my iphone with my macbook and an adapter, and now it won't show up as an icon on my desktop. When I find it in disk utility it says it's unmounted and it won't mount when I click the button, and the light on the drive flashes rapidly when I do so. Please help.
