A user just leaved a comment in another posting regarding USB sticks that he isn´t any longer able to remove all partitions on his USB stick / SD card. He see multiple partitions but is unable to delete them.
The solution is using diskpart here. So do the following
1.) Open CMD (run as admin)
2.) start diskpart via
diskpart
3.) now enter list disk which would look similar like my output:
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 476 GB 0 B
Disk 1 Online 232 GB 0 B
Disk 2 Online 14 GB 14 GB *
Disk 3 Online 28 GB 0 B
4.) In the case above we would like to remove every partition on disk 2 and 3. Keep noted that if you select the wrong disk here, you might kill everything on it. So make sure you are using the correct one via:
select disk 2
or
select disk 3
5.) check if the disk is relay selected with
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 476 GB 0 B
Disk 1 Online 232 GB 0 B
Disk 2 Online 14 GB 14 GB *
* Disk 3 Online 28 GB 0 B
There should be now a “*” in front of it
6.) Clear the configuration information from the selected disk via
clean
7.) Optional: To re-use the USB / SD card you need to add a new partition here (as you removed the old one) this can be done via:
7a.) Make sure the correct disk is selected via
list disk
if not make sure you select the correct disk with
select disk 2
The number might be different in your environment
7b.) create one partition for the whole disk via
create part primary
7c.) select this new partition via
select part 1
7c.) make this partition as active via
active
7d.) format your new disk
format fs=NTFS label=”14GB”
or
format fs=NTFS QUICK label=”14GB”
P.S.
This might also be usefull if the USB card was used in a unknown OS / system and you would like to re-use it.
