Remove and Fix Raspberry Pi SD Partitions

Raspberry pi 150I recently accidentally formatted an SD card for a Raspberry Pi that I normally use for windows. I went to reformat and lo and behold I was unable to delete the partition in Windows partition manager. I found a solution using diskpart. In about 30 seconds you will get rid of those annoying partitions that can’t be removed using diskpart. I managed to remove the 75MB and 77MB partitions very easily under Windows 7 and 8.

If you are trying to figure out which hardware would work best for you, consider reading the Pi benchmarks.
