Ok, I have an 2TB second HDD and after some updates from Windows10 Pro X64, started to be funny. I can open and see what is on it, I can copy files from it to my master HDD, I can watch movies, I can listen music, etc... What I can't do is to delete any of the files from it, "can't read from the source file or disk" error, copy nothing on it, same error and to create a folder on it, "error 0X801f0004 an unexpected error is keeping you from creating the folder. if u continue to receive this error, you can use error code to search help with this problem" I have checked my drive with Sentinel 4.6 Pro, no errors an 100% health, in Seagate Sea Tool all the testes are ok, only in Windows Check Disk it say that there is an error checking this drive. Please, help! Thanks.
