Can't reformate my external hard drive
I have a Toshiba external hard drive 2tb, I just got my first MacBook air. I plugged it in and followed the instructions without knowing what I was doing. My macbook formatted my external hard drive to a time machine drive. I found out how to take it off the time machine list, but I don't know how to make my EHD writable again. I want to use it like a normal EHD. Can someone please help me? My macbook is brand new this yr 2023 model. All I want is to drop files into it like a thumb drive. Any and all help would be appreciated. Thanks
MacBook Air (M2, 2022)
