Only solution that worked for me is :

CMD -> Attrib -h -r -s /s /d G:/*.* (use your drive letter instead of G)

You may check whether it is corrupted or locked. sometimes it will be not accessible if it is locked.

Hello,

I have HP-16 GB Flash Drive and for last 3 days trying different methods to Format it like:
1. Regedit ---> HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies. Change the value for the key "WriteProtect" to 0
2. Through MS DOS in the Computer Startup.
3. Through Disk Management.
4. HP USB Drive Format Tool.
5. and now the solution you posted. but still got no luck :(  .

every time it gives the same error "The Disk is Write Protected"

Any other Clue???

Thanks in advance.

Regards,

If the problem is persistent with the drive and you still can't copy files to it or format it after:-

1- You tried removing read-only permission from the drive properties
2- You tried formatting from Windows
3- You tried formatting from CMD using DISKPART
4- You tried editing the Registry solution (for WriteProtect word)
5- You tried the different free online tools like HDD LL Format tool and HP Format Tool

Then your drive is corrupt and needs the internal chipset S/W to be flashed, i.e. repairing the USB software. The steps below will lead you to get a small program to run on your USB memory-stick which is specific to your MANUFACTURER (make) and PRODUCT (model). If you don't want to go through the headache of the manufacturer's technical support then do it yourself as follows (which I source from here):-
1- Get Chip Genius portable application from here which you will use to find the VID and PID of the USB stick chip.
2- Search for the tool to repair your USB stick S/W from FlashBoot website . Search using your VID and PID from the previous step.
3- Search on Google for the name of the application you find in the "UTILS" column in the page from step 2 and the first link on Google Results (usually) will take you back to the FlashBoot website to download the utility to get your USB drive repaired.

It worked for me for my Kingston Data Traveler flash drive. It didn't work with all the common options for fixing the USB drive having "write protected", but the above solution I found after hours and hours of searching online and asking my computer-geeks colleagues.

Hope this helps! :bounce:

Yeah thats my problem, I cannot get the write protection off the usb drive. I have tried all the steps outlined by user "Samy Youssef" and he had mentioned after completing all steps and if your usb drive is still write protected he said to re-flash it with manufactures flash utility. I have downloaded it but I'm not for sure how to use it.

i appreciate any help at all I hate to lose this usb drive, i think its still good if i can get the write protection removed


thanks again
