Back in the 80's I would sometimes start my Saturday morning by watching cartoons, then jumping on my 1040ST and learning/writing GFA BASIC code, then transition to playing a few games in the afternoon, and around dinnertime visit a handful of BBSes. What a great time.
I just realized you mentioned it was an SD card. InitDisk can fix that too if you have an SD-to-USB adapter.
Steve Gibson's free InitDisk may be able to fix that USB stick. It'll delete all data, but might make the USB recognizable. Just run the program as Administrator and follow the prompts. www.grc.com/initdisk.htm
Sad fact: In December 2024, a little over one year ago, I bought a 32GB DDR5 SODIMM from Micron for $77.99. Today, that exact same stick is $354.99.
