Remove Write Protection on USB Drive & Memory Cards

Many times using your portable devices you get errors like the disk is write protected like in the image on the right hand side. So this can happen anytime due to virus attacks or anything can be the cause. So recently I got main from one of my reader namedsoundararajan so he was asking that his 2GB card has become write protected so what he can do, well there are two ways you can try to remove its write protection so check them below.
Firstly I will recommend checking for any physical lock on that card or USB, because many times company’s provide a lock write attached to the card for making it write protected, so check that up make sure its off and than also if you are not able to copy stuff to your card than follow below methods.

Removing Write Protection Using Registry Editor :

Well this is most preferred way of removing write protection as it does not include any formatting of disk or memory card. So you just have to manipulate a .reg key and that’s it.
1. Open Registry Editor by navigating to Star Menu > Run ( on windows 7 search for Run in start Menu ) now type “regedit” and you will see your Registry Editor opened.
2. Now Navigate to the following path :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

Now if you are not able to see the StorageDevicePolicies than no problem just download this.Reg File and double click on it, now restart your computer and you will have Storage DevicePolicies.
3. Now double click on the WriteProtect and make its value 0 and than click OK.
4. Now just close registry editor and restart your computer for changes to take effect, now plug your memory card or USB in and enjoy non write protected memory card.
