Move write-protect from flash drive - Lexar JumpDrive Classic Portable USB Data Storage Device, 128MB. (PD0128231) Media

Normally I'd make something this simple the very first step. Some USB flash drives come with mechanical switch on them that put them into Write Protected mode.

There can be very small slider switch.

And if this is the case, then you must move the switch to unlock position.

Write Protection on any portable USB Device can be applied by the physical lock provided on the card adjuster or some times provided on the pen drives, so make sure to make your drive not write protected by moving the lock in right direction.

But even after moving the physical lock for write protection the problem can happen due to some virus action. This happens when some virus or script which applies the registry hack to make any drive write protect when connected to the computer, In that case follow the procedure below to remove write protection from your pen drive.

1. Open Start Menu >> Run, type regedit and press Enter, this will open the registry editor.

2. Navigate to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

Note: If the registry key StorageDevicePolicies key does not exist, you will need to create it

Three possible sources for this problem, and three separate solutions.
The following procedures assume your flash drive is assigned by MSDOS to drive E:
---------------------------------------------------------------------------------------------------------------------------
PROBLEM 1: Pen drive write-protect switch set
SOLUTION: move the tiny switch on the pen drive from the icon of a padlock locked
toward the icon of a padlock unlocked
---------------------------------------------------------------------------------------------------------------------------
PROBLEM 2: MSDOS attribute set incorrectly on any/all files on pen drive
HOW TO DISPLAY CURRENT SETTING: START > Run... > cmd
C:\> E:
E:\> attrib /S /D

HOW TO FIX WRITE-PROTECTION PROBLEM: START > Run... > cmd
C:\> E:
E:\> attrib -r /S /D
----------------------------------------------------------------------------------------------------------------------------
PROBLEM 3: REGISTRY set incorrectly (targeted by virus or other malware)
HOW TO DISPLAY CURRENT SETTING: START > Run...> cmd
regedit
display HKEY_LOCAL_MACHINE\System\ CurrentControlSet\Control \StorageDevicePolicies

The valid values for this are 0=Disabled (meaning READ/WRITE), and 1=Enabled (READ only)
HOW TO FIX WRITE-PROTECTION PROBLEM: START > Run... > cmd
regedit
set HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\StorageDevicePolicies
to a value of 0 (Disabled)
----------------------------------------------------------------------------------------------------------------------------
A fourth way to "Fix" the write-protection problem would be to reFORMAT the flash drive, but
this "solution" merely resets the ATTRIB characteristic of the top-level directory of the
flash drive (while erasing all files on the flash drive), which is done better with the ATTRIB command,
and completely fails to address the possible write-protect switch or Registry issues.

Somewhere on the drive is a tiny switch, you need to move that switch.

There's a small "slider" switch that needs to be moved.

check the case of your flash drive, maybe there is a small knob or slide knob on the side, try to move it ,

If none, i suggest try to change it with new one, your flash drive is corrupted

Most USB drives don't have a Write Protection switch, but if yours does, then move the slider.

If it doesn't have a switch, the only way to use the drive is to format the drive. First, note the drive letter, such as E, F G for your drive. *** BE CAREFUL *** This will remove all files. Go to Windows Explorer, note the drive letter , Right-click and select Format. Again, BE CAREFUL not to format any other drive, just your removable USB drive.

Hope this helps.

theres a lock on the side of ur device...
move it so that its between unlock and lock
then do wut u want ;)

do you see any switches on the side of it ? if so move it to the other position and try again.
