Ok I'm pretty much a novice at this stuff but have picked up a few things here and there (mainly YouTube) so please speak slowly and clearly to me!
I had a 20" iMac. One day a few years back it just stopped working. It's got a ton of photos, videos, music on iTunes and some documents I'd like back. My brother removed the hard drive and we scrapped the rest.
Fast forward to now. I thought I'd try and recover the data. So I bought a SATA to USB cable. It didn't show up on my computer. In disk management it was there but unallocated. Long story short I accidentally formatted it 
I have purchased EaseUS recovery software..I can see it all there in theory but cannot preview it and it's taking an absolute age to recover to my (much smaller) external hard drive. I've selected the files I think are what I want to downsize the whole thing but I can't view them once they arrive there.
I'm assuming this is because they are meant for Mac and I'm using a Windows computer...does that sound right?
I have a trial of HFS explorer but it could not find the drive before I formatted it and now it says there are no HFS+ files present.
I'm stuck, can anyone help please?
