Okay, I think this was a very, very stupid mistake. When ATV Flash asked me which drive to reformat, I selected one of the partitions on my external. I expected ATV Flash to erase that partition, not the whole drive!! Now, the entire contents of my 1TB external are gone!! What should I do?
Can someone please help me? Is there a partition recovery tool that anyone could recommend?
Unfortunately if the hard drive was formatted the data will not be accessible. You may try using the Stellar Phoenix software available at the link below to recover your data.
