We have tried the prescribed methods to remove write protection from the pen driver however the issue seems to be other than Write Protection. As stated on Imation website: "If the write protect message displays on a flash drive without a physical switch, data on the device should be backed up elsewhere and the drive replaced. There are no tools to recover the write capability of the drive. If the drive is under warranty, contact Technical Support for assistance."
Kindly get back if there are any further queries.
