Restore Lost Capacity Of Your USB Drives and SD Cards

I was playing with the Pi hole on one of my old Raspberry Pi and noticed that my 32 GB SanDisk Micro SD card was showing only 100 MB as space. I tried multiple method to recover the card space but was unable to get it back.

Clean & format the SD Card:

Following method worked to get the space to it’s orginal:

1. Open run(Win+R) and type ‘diskpart’, Enter
2. Type ‘list disk’, Enter
3. Type ‘select disk #’, Enter (to select a disk, where # is the number of the disk Windows screw-balled. Usually, the device is disk 1, but it’s always best to make sure.)
4. Type ‘select partition 1’, Enter
5. Type ‘delete partition’, Enter
6. Type ‘partition’, Enter
7. Type ‘clean’, Enter:
8. Type ‘create partition primary’, Enter
9. Type ‘format’, Enter, this will format your drive
