Over a few years I've installed several plugins and extensions as they developed along with unraid. Now my drive has leftover bits and pieces of uncleanly installed old plugins, and I'd like to start it over fresh. A pseudo 'format' of the flash drive I guess you'd say.

 

How can I best erase my drive, drop my drive settings, config, usernames, pro key, etc back in place resulting in a pure 'stock' setup again?

 

 

Save your key file;  then just format the flash drive and reload UnRAID from the current download ... and then copy your key back to it.

 

Then when you boot, just assign your drives to the array, enable shares, and install any add-ins that you still want to use.
