    pen drive shows 'write protected'
    « on: January 25, 2010, 10:39:37 AM »
    I have a 4 GB transcend pen drive. I used it at my office and  when I wanted to delete some data from it ,it shows drive is write protected. I have an updated antivirus named guardian (from Quick Heal) and this application found no error on scanning. How my pen drive will be usable again properly ? Please help me.

    It has to be a setting in the drive itself or a switch on the outside.

    What type of pen drive is it? Long, short, or skinny?

      1.  This link looks promising:  How to remove write protection from USB flash drive.

      Basically two different registry edits are presented:

           a.  My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies.  Double click on the string "WriteProtect" and change the ‘Value data" box from "1" to "0".  Intuitively, it seems logical to set write protect off.

      Another post suggests if the "WriteProtect" string doesn't exist, then just create it and set it's data value to "0".

           b.  My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR.  Couple of posts in the thread say change data value of "Start" string from "3" to "0".  I don't know what functionality the "Start" entry controls.

      2.  Reference(s):
