I was going to use my HP 32 GB flash mem to install a new version of Linux on my HP system, but after I tried to format it, the icon immediately disappeared from the screen and I can't find it anywhere in my files. The only icon that shows up is my HP 64 GB flash mem, which I'm going to use to store and play C=64 games. I tried inserting my 32 GB flash mem into my W10 system and tried a quick format on it, but that didn't work: the computer said that it was a read-only device. It showed up on my list of drives, though. Any ideas on how to fix this problem?
