Hi. I started mining using Windows on SSD (1st rig). I have 2nd rig on Ethos mining to the same address, using ethermine pool.
I want to reinstall the Windows rig. I already have a copy of my keystore. I know my address. I remember my password. Is there anything I should backup before I reformat my SSD on the 1st rig? Heard so many horror stories that cannot access their balance, etc. Just want to double check.
