Sony pendrive and ext3

  1. Hello All

    I had occasion to format a Sony pendrive to EXT3 in order to copy a 4.8G file that FAT wouldn't accept.

    Having done so I now want to reformat it back to FAT32. Windows 7 sees it as EXT3 and I can read the file on it, BUT when I come to reformat it says the drive is locked. this particular model does not have write protection on it. Any ideas what I might do to restore it back to its former glory?/

    Thank you

    Is that the only USB storage device appears to be write protected? As i know there's a registry thingy that protects all (if that might apply)

    * Click Start->Run, enter: regedit
    * Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control
    * If sub-key StorageDevicePolicies exists, rt click then delete it

    /* edit */
    And, of course, the usual precuautions about first creating a system resotre and backing up registry , etc. etc. apply

    yes this is the only usb device affected and no, that key does not exist in the registry.
    Thanks anyway for your suggestion. Am thinking of going back to Gparted and seeing if I can reformat to FAT32 in that.

    Thanks again

    yes that did it. Having not used Gparted, I didn't realise how versatile it is. All is as it was now.
    Thanks for taking your time to help
