I have 2 USBs that I was using to install Linux systems on both of them. I had elementary os on one usb and tried to use it to install it into of the USBs. Everything seemed fined, I chose the USB as the device to install it. There was no reason why this should have happened, but it wiped out my internal HDD. I've tried to run several recovery probrams: Easeus, acronis, wondershine recoverit, etc. I'm not sure if I can get things back now since it might have been formatted, but I had so much encrypted info on there it's killing me to think of losing.
