F23: USB key won't work after reformat

I have a 16GB USB key (SanDisk Cruzer Glide, if it helps solve the problem) that I tried to put Linux on. As part of my crazy attempt, I booted to Windows (I have a dual-boot) and reformatted my drive to FAT32. Now Fedora won't read it. It recognizes its existence when I put it into the slot, but only so far as its name and that it's a thumb drive. When I try to open it, it says "Unable to mount location". Windows can read it just fine.

Did I mis-format it, and if so, what formats can Fedora read?

Normally FAT32 is detected by Fedora. What you can try at the moment is boot into windows and format it again as NTFS. Try connecting it to Fedora and see if it is being detected.

If you haven't reformatted yet, put it back into your Fedora box and run this command as root: fdisk -l remembering that the last character is a lower-case L, not the number 1. It should be able to tell you how big it is and that it's formatted FAT32. If not, something probably went wrong when you reformatted it.

If this USB stick was used as Fedora installer media, the partition scheme is really unique and can seemingly break a USB stick similar to how you describe, although I'm surprised it doesn't also confused Windows. If you're prepared to lose all data on the USB stick you can blow this away with:

sudo dd if=/dev/zero of=/dev/sdX bs=1m count=2

That's slight overkill but it'll do the trick. Now it needs to be partitioned and reformatted. Fedora definitely can read/write FAT32.

Turned out to be a misformat. Used GParted to fix it. Thanks for the help.
