When I try to format my bootable Pen Drive, the computer shows it is write-protected. I have tried some methods, like editing regedit and cmd mentioned online, but all of that did not work. How can I bring back the pendrive to its normal working state? Thanks in advance.
According to your description, I can learn that your bootable Pen Drive has been in a state of write protection. Therefore, if you want to fix the bootable Pen Drive write-protected error, you need to turn the bootable Pen Drive into a non-write-protected state. Based on that you have tried some ways, like editing the registry and cmd, I would like to recommend some other methods according to my experience.
The first way is to try checking the physical switch on the Pen Drive. You need to see whether a physical switch is on either side of your pen drive. Actually, the physical lock switch is designed to control the ability to read and write on the Pen Drive. Most modern bootable pen drives, such as SanDisk, Sony, Kingston, and many other famous brands, are designed with physical lock switches. Therefore, you should toggle the switch to the position of "unlock" from "lock." As a result, you'll be able to format your pen drive freely again without meeting the disk is a write-protected error again.
But if your bootable Pen Drive doesn't have a physical switch, you can try the second method. I suggest that you can use the third-party software, the Qiling Disk Master, which will offer you a simple and operable way to fix this error. You can try this useful method.
