Troubleshoot Disk is write protected

[nishaddesilva]

I'm having trouble formatting or copying files to my Kingston pen drive. It says the disk is write protected. I tried registry fixes, diskpart etc. Still no success. Please help.

Are you able to format USB with HP USB Disk Storage Format Tool ? (run as admin)
HP USB Disk Storage Format Tool 2.2.3

It is often the sign that the pendrive is disfunctional. But you also can try this:

HP tool also says the same thing.

If you tried every step of the following

Spoiler

Then it's maybe the best to download GParted, burn it on blank CD or other USB device, and try formatting problematic USB from there

I read somwhere that it is possible to find the factory software by the chip number, that can format disfunctional pendrive (if GParted fails).

Here are more details:
"If for no reason you encounter "The disk is write-protected. Remove the write-protection or use another disk." – message for your flash drive it is more likely than not that this is due to the failure of controller’s firmware. In this case you need to flash it by using recovery utility suitable for controller of your USB flash drive. Read above how to find correct utility for your flash drive knowing its VID and PID"

"First, recover the functionality of the flash drive’s controller. To do this find utility to work with it. If you know both the controller model and the name of the flash drive manufacture then a suitable tool can be found on the manufacturer's website or somewhere else on the Web. If you are unaware of the controller model use controller’s VID and PID codes to find it. For example, VID = 13FE and PID = 1D00 are relevant to PHISON controller. To find VID and PID for your flash drive use the specialized utility such as CheckUDisk 5.0. You can also look up the VID/PID (vendor/product ID) in the registry under HKLM\SYSTEM\CurrentControlSet\Enum\USB. However, the registry key does not always indicate the manufacturer, and rarely the chipset. (There is a companies database that lists VID and PID against company names and type of controller they used on specific flash drive. This list changes almost daily.) Viable for determining PID, VID and type of controller for your flash drive is ChipGenius tool."

This tool also doesn't show the chip part number to proceed
Any more solutions?

It says it's not read only. But when I try to format it still says it's write protected.

It says it's not read only. But when I try to format it still says it's write protected.

Have you found the software from manufacturer web page ?

 

[nishaddesilva]

Have you found the software from manufacturer web page ?

There's no software for that on the Kingston website.

 

[BoraMurdar]

There's no software for that on the Kingston website.

So you tried formatting it from outside of Windows?

 

[Niente]

If you try formatting with Linux it probably has no effect. In my opinion it has a hardware problem, and that is the reason by it seems 'write protected'.

Anyway you can test this:

Hope this will help you...
for windows only

Click start
then run regedit
go to this directory HKEY_LOCAL_MACHINE\SYSTEM\Currentcontrolset\control\
if you can't find StorageDevicePolicies under control folder
then make some new one. Follow this steps:

step 1:
go to this directory HKEY_LOCAL_MACHINE\SYSTEM\Currentcontrolset\control\
again and right click control folder

step 2:
select new, then click key and rename the new key #1 folder into

step 4:
rename word newer folder into WriteProtect, then double click WriteProtect
and change the value data into 0 with the hexadecimal base, Then close Regedit

step 5:
open my computer and refresh it 5 times without doing anything to your usb, and
properly eject your flash drive

step 6:
plug in your usb again into your computer and format it using exFAT instead of fat32


Now, you can use your flash drive again....
