Hello again, fzabkar! I have two more questions if you don't mind. 1) Will my external drive be reliable and functioning as it used to after initialising and format? 2) All this happened because I tried to download Linux mint all by myself . Do you think this is too risky?Windows Disk Management can initialise and format your drive (after you have recovered your data).
You can recover all your files for free if you are prepared to sit through multiple sessions of DMDE.
