So; I think I'm fucked.
I'm trying to format my old PC to sell it, aaaand I went into a few Linux Mint forums to find the easiest way to safely erase data
I booted up mint from a USB drive , set it to erase and substitute all data from the disks menu... And it's frozen. At 42,6% , for the last few hours. The Panel is also missing.
I can't just disconnect the USB stick and idk what happens if I try to reset it mid formatting so ... What do I do ?
