1. open command prompt (cmd.exe)
2. type "diskpart"
3. type "list disk"
4. identify which one is your USB disk.

5. type "SELECT DISK n", where n is the number of your USB disk.
*** BE CAREFUL AT THIS PART. Selecting the wrong disk might delete your hard drives ****

6. type "clean", (you may need to repeat twice or thrice). If it doesn't work, don't proceed with the next instruction :-(
7. type "create partition primary"
8. type "select partition"
9. type "active"
10. type "format fs=ntfs"

I don't know what you mean by write protected "tab"

Are these instructions more specific ?

*1. Open Start Menu

*2. Run, type regedit and press Enter; this will open the registry editor

*3. Navigate to the following path:

4. Double click the key WriteProtect in the right pane and set the value to 0 In the Value Data Box. Press OK

*5. Exit Registry

*6. Restart your computer and re-connect your USB pen drive on your computer.

There is 8 ways to remove write protection on USB flash drive
1- Scan your flash drive with updated antivirus
2- Unlock your memory card or flash drive "some flash drive have lock/unlock button .
3- Make sure the files you want to move a printable
4- Fix write protected problem by DOS commands as following :
- From Windows start menu click on RUN or you can show it by clicking " Windows symbol + R " from your keyboard then write CMD
- Write this cmd order " diskpart " Then windows open new windows press YES.
- Write this order " list disk " then click enter ,DOS will show the disk devices in your PC .
- Write " select disk 2 " then enter .Note select your flash drive or memory card disk label 1 or 2 .
- Write " attributes disk clear readonly " then enter .

5- Fix write protected memory card by modifying windows registry by doing the following :
- Open "RUN" as we mentioned before .Write "regedit" then press enter .Click yes to open windows registry editor .
- By clicking your mouse from the windows registry editor , try to reach this path "
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies "
- After you reach this path ,search about this registry key " WriteProtect" then click right click "modify" , you will find key value 1 replace it with zero value then click ok

6- Update your flash drive firmware " first get chip genius report then copy chip vendor and chip vendor model and search in google about your flash drive firmware .

7- Try other format programs like " Hp disk format tool " and HDD low level format

Try this:

For USB drives:

1. Open Start -> Run...
2. type diskmgmt.msc and press enter
3. right click on the partitin you want to format (where the leter and size is)
4. select 'Delete Partition...' and confirm
5. right mose button in the same place and select 'Create partition'
6. select primary partition
6. select size, file forma, disk leter, label etc should be all right if you leave defaults.
7. click ok

This will recreat the partition and format it in proper way. Helped me and will help to most of you if you have problem with MBR.
