So I have a 256 GB thumb drive. Threw Windows Media Creation Tool on it. After I was done with Windows, I formatted it and noticed that I only had 32 GB usable. The other storage was there, but I couldn't access it. So I used diskpart to create a primary partition. Did a long format, all good, I can see all my available space. Plugged it in a day later and I can't see the drive under "This PC", no Windows sound was made when it was plugged in. Doesn't show up under "safely eject" and there's a slow red glow/pulse coming from the thumb drive that normally lights up when I'm reading/writing data - but at a much faster pace. The thumb drive shows up under Disk Management. Can't eject it from there. The entry is just blank. When I right click > Volumes it just says - Capcity: 0 MB / Unallocated space: 0 MB / Reserved space 0 MB. Did I toast this drive somehow? Can I fix this?
