  • Most flash drives will go into permanent write-protection to prevent data loss if it finds any issues in itself. This happened to me after I washed my SanDisk pen drive thrice. Or you may have used up all its write cycles.

In most cases the following steps will solve this kind of problem:

  • Open command line as an administrator.

  • type: diskpart

  • list disk

  • select disk x where x is the number of your pendrive

  • attributes disk

  • If read-only is yes, type: attributes disk clear readonly

If this doesn't solve your problem, I suggest trying the Apacer USB3.0 Repair Tool
