Hi, I bought a new external harddisk because my old wasn't enough. Anyway I transferred files from my computer and old external harddrive to my new one . BUT then mistakenly I deleted all the data on the new harddrive. I selected zero data option while I pressed Erase Data but then stopped it after 10 seconds. Unfortunally I can not see any data on my external harddrive. Can you suggest me a easy to use tool to recover my data?
