  1. Only solution that worked for me is :

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

  4. 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.

  10. Hello,
    I have this same problem and I have tried all the solutions that you had listed so I downloaded the utilities that you had said if the others didn't work. The problem is i cant get the program (AlcorMP_AU698x_RT_v1.0.0.14_L0117) to recognize my usb drive. I'm not sure how to use the program. Can you help guide me onto how to use it.
    Here is what the Chip Genius program listed on my USB drive:

  11. 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

    When I searched my flash drive's (flash drive is pqi) PID and VID, it didn't have anything under the UTILS column so I searched the chip part number instead (that seemed to be the most unique among all the info provided by Chip Genius). Found a utility by the chip vendor, had to run it a couple of times, but it got the job done! Thanks Samy!

  17. Hello guys

  18. with windows 7 I get this from time to time I just stick the pen drive in my Linux rig and format it to fat32 and they work fine back in the windows 7

    I did see guys say that can work with xp as well I think these a bug in 7 [maybe 8 -8.1??] that causes this but formatting them in Linux seems to fix that issue for me ??

    good luck
  19. PLEASE pay attention. This works. Open your start menu, in the search bar type disk mana (and it should autofill to the right one) which is to create / format etc. Once here, it lists all your drives. Find your USB drive, you'll note on the left it says 'READ ONLY'. Right click it. Tell it to go offline. Wait for that to process. Right click it again, bring the drive back online. And it's fixed. Thank me, by replying and letting others know that this is the correct and only fix you need.

    No, it's not. The same symptoms can be caused by multiple problems. Just because it worked for you doesn't mean it will work for everyone.
