I wanted to upgrade my PS4's Hard Drive because 500gb isn't enough. I followed all instructions properly. I made the PS4 and UPDATE folders with the correct naming method and all, got the right update file (says it's 837mb), used a USB using the FAT32 format, got a Hard Drive with the right specs (see below) and all, yet whenever I Initialize PS4 (Reinstall System Software) it thinks for a moment then comes back with "The update file is corrupted (SU-30645-8)." I've even used 3 different USB sticks with the correct formatting done. I thought it might be the Hard Drive, but it fits and doesn't appear to be having any troubles visually or audibly. I just don't know what's wrong...some help would be greatly appreciated.

Please help.

I didn't find the right solution from the Internet.
