Yes, you are right but my drive is not readable its showing me to format the drive as soon as I connect my drive to computer.
That's why I wanted to know if there is any possibility to recover file after deleting drive then reformatting or zero chances like a low formatted hdd??
There is a very small chance less so because your trying to pull files off a HFS onto a NTFS FS. Without some way to read the files now I would not count on being able to recover them later. Possible but highly unlikely.
Your best bet will be a fsck from a Mac then trying to read the files.
