My 500GB (Seagate) Hard Drive, 32GB (Moserbaer)USB, 8GB (Kingston)USB is write protected and i am unable to write any data into it.
I try a lot of ways which already mentioned on internet like DISKPART, DEVICE MANAGER OPTION, FROM REGISTRY and OPEN SOURCE TOOLS.
If anyone suggest me Solution.  

Could be a physical write protect switch on the drive itself, could be a configuration setting in Windows:

Hello Satyendra
Most likely your disk has ATA password which is stored in platters .Unless you remove it you will not get sector access.
If you don't have data you can securely erase disk which will clear password.  

I tried all these things but didn't not successful. Before Write Protect its work Normally.  

Another way to block write access to (unencrypted) devices in Windows is the Bitlocker policy.  

If all 3 devices, HDD and two USB drives are blocked to write, did you get ransomwared? I mean did you get a message of paying a ransom to unlock?  

Did you try the DISKPART “attributes disk clear readonly” command as mentioned here?
