How to format write protected sandisk pendrive

Try following:

Open "Computer Management"
"Storage" -> "Disk Management"
Make sure to find the correct device on the bottom panel
Right click on the partition rectange -> "Delete Volume"
Right click on the appeared grey area -> "Create Volume"

edit: If that doesn't work, you might need to use DISKPART utility to recreate filesystem and main partition, like in this question:

Start a command prompt, and start the DISKPART console. List all of your disks by typing LIST DISK, then select the proper disk with SELECT DISK # (where # is the SD card). You can then type CLEAN to clear the partition table on the card, effectively blanking it. MAKE SURE YOU SELECTED THE PROPER DISK BEFORE RUNNING THE CLEAN COMMAND!

To create a primary partition to reuse the space on the card, type CREATE PARTITION PRIMARY. This will then reallocate the previously "cleaned" space.

To format, type FORMAT FS=FAT32 QUICK...

(Ignore the SD card being mentioned)

edit 2: If that doesn't work try suggestion from this link:

1) list disk
2) select disk #
3) list volume
4) select volume #
5) detail disk
6) detail volume
7) attr disk clear readonly
8) attr volume clear readonly
9) detail disk
10) detail volume

edit 3: This answer to a similar question suggests that the drive may be faulty:

I understand that you are getting write protection error while
accessing your Cruzer flash drive. The flash drive has detected a
potential fault and has become write protected to prevent data loss.
There is no method to fix this. You will need to backup your data and
replace the flash drive. ...
