I have had a sandisk cruzer pop for about 3 years now and all of a sudden it has lost all its volumes and partitions and i cant put more back on it, it comes up as being plugged in on all pcs i plug it in on though. Please help i need it for school work. It says its empty and has no files on it but for some reason with microsofts own diskpart it wont let me create a volume or partition on it? And in disk management it comes up as not initilaze but with the button to initialize blurred out.

I have tried on latest mac OS X and windows 8.1

Please someone help me fix this problem or tell me wether it is faulty because it is still under warrannty

:smiley:   Hi CrankyGamingMat,

Dear member of SanDisk Community, welcome.

Please, 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.

The drive will go into write-protected mode to prevent data loss.
_ There is no method to fix this. _

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

@ CrankyGamingMat

This is not a Write Protection error problem.  USB drives,  UFD drives as Cacho refers to them as, with the Write Protection problem are readable and files can be copied off of them.  This one is unreadable. 

See if a Windows CHKDSK scan finds any errors with it.  If it can’t then Cacho’s initial diagnosis is connect: " return it, because is dead, ist kaputt.".  If it is still under warrantee you will get a free replacement.  Good luck.

And be very careful running files from unknown sources.
