Raspiblitz: Prompt+Confirmation before formatting the HDD

[fluidvoice]

Not sure because the drive has been formatted by raspiblitz.. possibly I accidentally formatted it to NTFS or something when I set it up initially to sync blockchain on my desktop. it was a while ago now.

Any recommended file recovery tools for Ubuntu? I'm hoping the blitz hasn't written over the data and corrupted it.. there is a chance it has because it formatted the drive and added ssh folder + raspiblitz.conf file.

Maybe for future release it would be good to have a notification saying blockchain not found and need a Y/N confirmation before it formats the drive in case we put the chain in the wrong folder or set the wrong filesystem on the drive.

Prob not worth the time/trouble to try to fix it. I would download the torrent again if you don't already have it and sync again.

I agree it should prompt. @rootzoll see : https://github.com/rootzoll/raspiblitz/blob/e38c48e54536a6233a0062b99858d43685635d80/home.admin/10setupBlitz.sh#L256 It prob should not reformat the drive without prompting the user to confirm.

TODO: The script should check the HDD and ...

• when its the wrong format .. ask to reformat in ext4 or cancel
• when its ext4 and not empty .. info on how to prepare a correct Blockchain HDD and ask if format or cancel

I would like to ask for an extra confirmation as well.
I just accidentally formatted a HDD with a complete blockchain downloaded on it, and an LND wallet on it as well.

Starting with v1.2 the RaspiBlitz will ask before formatting the HDD.
Closing this issue.
