My seagate 500gb external portable harddisk was working yesterday, but when I plugged it in today, it's memory became 0 bytes. I checked disk management and it said the harddisk (which has only 1 partition) has a RAW filesystem, instead of the NTFS i was expecting.
How can i recover files from this? I needed my thesis files here and hoping someone can help me graduate

this is what happened when i used test disk.
i selected INTEL in the type of partition. when i analysed, it said READ ERROR so i did quick search, and this is what happened. it seems to take so long and is not yet finished. am i doing it right?
i would be really grateful to anyone who can help me
