The extra partition you see there may be the drives boot partition, have you recently cloned to this drive? if you did, check your windows disk management tool to look at all drive partitions including hidden ones. Check your original drive and see if there is another partition on that drive that is similar to the f: drive in this SSD.
The SSD has nearly 900 hours on it and the F: partition suddenly appeared two days ago. I have no idea how it appeared or why and I would like to figure out how to remove it.
My original drive didn't have an extra partition. This f: drive is causing problems for me. For some reason, I can't back up the SSD. I will have to get rid of the SSD and switch back to my old HDD and try again.
chances are that the f partition showed up when a windows upgrade occurred. Especially if it is very small and seems to have no data.
Inside diskpart the command is
select volume = f:
remove letter = f:
