it is this hard drive:

it makes no sounds or noises on my mac but when I plug it into my windows machine it does make a noise but then there is nothing in my computer and it will not recognise the device at all
Toshiba E05A100SBU3EW_C STOR.E ART 4 1TB USB 3.0 2.5 inch Hard Drive - Black
warranty is valid but I really hope I can save the files
