HI, are you using this in a Mac or Windows? casue it might not be formatted in the correct format for Mac. It should be Formatted in Fat32
Some USB flash drives have a mechanical switch on them that puts them into Write Protect mode. This can be a very small slider switch which may have caught on something in your pocket or computer case. If this is the situation, then simply move the switch to the unlocked position and try to copy files again. It should work now.
If there is no switch, Check the File or program you are trying to copy. Right-click on the file that you’re trying to write to and then click on Properties. Now you’ll see some options at the bottom of this window and one of them is Read-only. Make sure this box is unchecked and then click on the Apply button. You should now be able to write to this file.
There is also a Registry fix we can try, but you MUST first BACK UP, your current Registry.I will explain later if the above don't work.

Dear member of SanDisk Community, welcome.
Please, try the Cruzer in other PCs, and see if the problem continues.
If still bad, do not grieve more friend, return it, because is dead, ist kaputt.
Write protection errors occur when a UFD detects a potential fault within itself.
Contact SanDisk Technical Support who will replace the device if it's authentic and is within warranty.
To obtain the internal data of the UFD, you can use (portable apps, free): USB Flash ChipGenius 4.00, http://filecloud.io/rqa7etmv
To find out more on this, see here:

" i tried it in other pc's too but the result is same."

Windows Explorer will allow copying the files to the hard drive and not require downloading more software..
Important files = Backed up files
