Time Machine Drive
My sister gave me her M1 Macbook Air but asked me to back up her stuff. I created a time machine drive and today she got another macbook so I started to use the time machine drive to get her up and going. Everything was going well til the transfer stopped and asked me to restart. I did everything again but now the drive won't show up on either hers or mine. Tried different usb adapters, tried to see if it was the drive itself but it shows up on windows partition and even on seatools but it says that no data is on it. My question is if there's a chance that the drive got wiped for some reason during the transfer?
