USB Flash Drive Cruzer Blade 4GB is write protected

Since I have this device (3 months) it is the first time I get this message:

  • cannot access to dmBackup.dll because device is write protected

How can I get through?

The device seems really impossible to be written.

Contact SanDisk driectly about a warranty replacement.

NO way. It contains my personal info.

I am interested to know the technical reason why it does appear the Write Protection info.

Hw problem? Sw problem?

It is not worth of money, it has to be the evidence of professional attitude.
