so my hard drive has been through a lot that brought it to this stage: first, I plugged my hard drive into my ps4 (because I have movies on it) to see if it would work. whilst I was looking for it on my ps4, I clicked a bunch of stuff and I think I formatted it but I'm not so sure. then, when I realised I couldn't play a movie, I removed it from the ps4 and plugged it into my windows laptop, to which I couldn't locate it on. like, I could hear the connecting sound and I could find the hard drive when I wanted to eject it but I couldn't locate it on my computer so that I can open it. this is when I started surfing around google to fix it, which made me eventually change my letter path from 'a' to 'k' and when I did that I think I IDIOTICALLY formatted it, so, when I went onto my drive, EVERYTHING was deleted. the only reason I'm so annoyed and hurt is because on that hard drive I have a bunch of photo memories since 2013 and a bunch of files for my mum (I haven't told her), and movies I've spent 6 months downloading. the only way I could find to fix it was to download and pay for a software, which I just can't afford right now. so, technicians and computer people, even though I'm a massive idiot, please help me I'm desperate.
