How to remove write protection from your usb or sd card using cmd

(Make sure to watch in HD!)
Learn how to remove write protection from your usb or sd card using cmd (the command prompt). This works for windows 7, 8, 8.1 and it may work for other versions of windows as well such as xp and vista.
UPDATE:
Please make sure you are doing this as administrator or it may not work!
Please email me if you have any questions or feel free to comment below!

Here is a copy and paste of what is typed in the video:
Objective: Remove write protection from SD Card or Flash Drive and format
Before you begin: Make sure your desired card or drive is already connected; also backup your data ahead of time to avoid any costly mistakes.
1. Go to the cmd screen by hitting your “windows key + r”
a. Type in “cmd” and hit “enter”
2. In the cmd window type:
a. “diskpart” (click yes when prompted, it may take a little while to continue)
b. “list disk”
c. “select disk” _(1, 2, 3 or whatever it is; you will know which one it is based on it’s size eg 64gb for example or whatever size your card or drive is)
d. “list volume”
e. “select volume” ¬_ (make sure you pick the right drive number)
f. “ff:”
g. “attr disk clear readonly”
h. “attr volume clear readonly”
i. Some may get the following error: “ virtual disk service error: the operation is not supported on removable media” or something like that. I got that but this still works.
i. “detail disk”
j. “detail volume”
k. “exit”
3. Safely remove your card
4. Reconnect
5. It should work like before. I recommend reformatting with default settings which you should be able to do now. Just remember to backup your data first or it will be lost!
