I strongly believe that Sandisk is faulty. I have come across some situations like that. In my country we see different qualities of this memory stick. Perhaps, you have the second-grade version that easily goes bonkers when formatted in different formats in few times.
It will go to trash soon after a copy content, and the SanDisk Cruzer Switch will be never on my desk … this what I find as a solution … thanks for you all for helping me ...
my lexar was bad and acted strange.. i reflowed it with kester 961 flux and works great again. happened 4 days ago. however in your case.. i would boot a different os like linux or gparted and try there. could be upper/lower filter or virus in pc/ antivirus.
Doesn't Do The Work Too under ubuntu But Something I don't understand, is this : It is Connected as a Hard Drive on task manager ??????
Open PowerShell and type Get-Disk Find your removable drive and take note of the number, then assign the disk object to a variable. For example: $USB = Get-Disk -Number 6 (this assigns your removal drive (number 6) as a disk object assigned to the $USB variable). From there you can pass the disk object assigned to $USB and remove the read-only status $USB | Set-Disk -IsReadOnly $false
Of course because some several posts above I'd figure out that usb stick is damaged. Replace it I'd advice.
