My SanDisk Cruzer Pop is showing that it is permanently write-protected, as you know, there is no switch. I did some research and it shows that I need to do a low level format. It would be great if you could just help me out with the problem and email me the required software so that I can start making use of the Flash drive again. Thanks in advance.
this happens when the controller detects a fault in the flash. it locks it into write protected to prevent data loss. Backup the data and contact sandisk support to check the warranty status.
