This is more of a curiosity than an actual problem. I have a 16GB flash drive that I installed Linux on. Later I decided that I didn't want the Linux to be on it, and used Linux to format it FAT32. I plugged it into my Windows machine, and it lists it as a "Local Disc." I reformatted it FAT32 under Windows, and it still listed it as a "Local Disc."
Again, this is just out of curiosity, and I plan on installing more Linux OSes on it soon
