What is the problem?
I used the Raspberry Pi instructions to format a 64 GB microSD card in FAT32 and load NOOBS on it. I then used it to load Raspbian on a Raspberry Pi 2. I then realized I needed a fresh microSD card to try out OctoPrint so I started to try and recover this microSD card back to a single FAT32 partition. I am not sure exactly what I tried first, but reading on the Internet I found the diskpart command and Disk Management in Windows 10. I lt and used diskpart first to view and clean the card, but diskpart could only see the '2.something" GB FAT32 partition, so that is all that it worked on. The Linux partition was still there as far as I could tell, but diskpart did not show it in a list of partitions on that card. After I cleaned the card, I tried for format it in diskpart, but it only formatted the small partition that Windows recognized. At this point I had a 2.something GB FAT32 partition, and I realized that the OctoPtint image creates a Linux partition when it loads and changes the size of the FAT32 partition to compensate, so I loaded the OctoPrint image on the card thinking that the image will use the full capacity of the card, but it only used the 2.something GB FAT32 partition. Next I found Win10 Disk Management and I looked at the SD card there and saw only the 2.something partition existing on the card. No free space and no other partitions. Everything else was simply gone. I deleted the FAT32 partition thinking this might then show me 64 GB of free space, but it did not. At this point on my Win10 computer this microSD card does not register at all. When I plug it into a reader in a USB port it shows up as "No Media"
Can anyone offer solutions, or a tool that will definitely allow me to see the full volume and all the partitions and free space on it?
What did you already try to solve it?
