I have a USB flash drive, which I made bootable for use as an anti virus disk. After formatting the drive, whenever I copy some files to it, it shows an error:

The disk cannot be written to because it is write protected. Please remove the write protection from the volume in drive \Device\Harddisk3\DR13.

Write Protect Error

there many things you can try to get rid of this bug:

  • try to locate a switch on the usb stick and use it (i guess you probably did that already)
  • eject the usb stick and put it back in and look if this has fixed the problem

now to more advanced stuff:

  1. format your usb stick using low lever formatter
  2. the partition and all data on the stick is now lost you need to create the partiotion again: press win+r and run diskmgmt.msc. Select your drive choose ntfs and format it
  3. check if it helped

so and the last thing you could try:

  1. press win+r and run regedit
  2. go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
  3. find the key "StorageDevicePolicies" if it does not exist create it
  4. now create a new DWORD "WriteProtect" and set the value to 0

i hope this will solve your problem
