I was formatting my microSD when I discovered this Does it matter what I put for the volume label? I was thinking of naming it something funny but I'm afraid it would ruin the micro SD. By the way, I use this Micro SD to store my DS games.
You can just edit the name whenever if you want to. And during formatting it's just there in case you have man drives like I do. I just name mine like SCDSTWO or AK2i [Insert Name Here].
