So my toshiba external hdd 2TB had files of about 100gb or something. Around an year ago I tried connecting it to an Android phone when I don't know what happened but the hard drive got corrupted or something now all the files are in gibberish and after searching help for the whole time I found nothing useful and have some important data that is not backed up anywhere else. Please help as much as possible.
Then it boils down to - how important are those data for you, e.g. how much are you willing to pay? I'd ask because I think having a professional recovery company is the only reasonable solution for you.
