During my recent Linux distributions experimentation, I noticed a few times that Windows 8.1 would no longer "see" a particular USB stick I was using. It would appear within the device list, would test correctly but would not appear in the left-hand pane in explorer.
I learned that this was because one or more of the distributions I was testing would, for unfathomable reasons, prep the USB stick strangely.
Why Windows wouldn't just offer to format the stick is unknown to me.
The solution is done under Linux:
- Remove GPT
- Create it anew
- Make a partition
Follow the Slax install process.
- Perhaps optional.
Perhaps there's a solution while in Windows, but I haven't pursued that.
