Im not sure what happened in between... Nothing I think. I may have deleted or added files and/or directories, but obviously that wasnt "in between" anything, it was either ON linux, windows, or mac. So i dont understand why it would be a problem.
But i have realised that if i go to the F:\ or whatever drive relating to the hard drive, and then type eg:"F:\Music", it will show me the music folder with all of the contents - so its all still there.. but when i go back up a level to the hard drive, i still cant see the music or any other folders. And when i plug it straight into my TV, i can still see and watch movies etc on the hard drive... so its all still there.
I guess I'm not really answering any of your questions, but I may have unmounted uncorrectly, deleted files, etc.. the main thing i dont understand is that i know 100% that its all still there, but i just cant see the files.. and yes, i can access the files if i type the path in the address bar, but i dont know what else is there other than what i type if you know what i mean
hope that helps. appreciate your thoughts/help
