Riddle_Decipher, I appreciate your help and your prompt reply. I wasn't very clear when forming my question I'm sorry. So I have a large amount of important files already saved to my 2Tb external HDD which I don't want deleted or damaged. Now I'm concerned that if I do a computer back-up to this same external HDD it might format the drive, or delete the existing files already stored there. That would be a disaster for me. So my question is, if I did make a computer back-up to this same external HDD, will the back-up process delete or affect the existing files (which I wish to keep) that are already stored on the external HDD. Or is it safe for me to go ahead and make the back-up to this ext. HDD? Elisecares.
Thank you for replying with this overwhelming and detailed response 😉
I appreciate your time and efforts,
It depends on the software you are using, so be cautious and make sure you've made necessary changes to the settings as some backup programs format the external drive and copy the data from the external source and some create a copy while leaving the existing files on the drive.
Ensure you select your preferences and then create the backup.
