Hi,
I suggest you to try the following steps to remove the write protection of e-reader.
The e-reader might have a write-protection button on the side that has slid down. Push the button back into place and try inserting it into the computer again. Read the manual that came with the e-reader for help.
Method 1:
If the issue persistsYou may try the following steps to delete the write protected files.
a. Press Windows key + X and type
regedit.
b. Go to
HKEY_LOCAL_MACHINE > SYSTEM > CONTROL > StorageDevicePolicies
c. Locate “WriteProtect”, double click and change value from 1 to 0
