1. Download and unzip latest firmware from;
http://www.samsung.com/global/busine...bbs_msg_id=386
2. Make a bootable USB drive

Note: The last part where it says '...copy CTXXM.EXE firmware.....', ignore that. Instead copy the HD204UI.exe firmware you downloaded from Samsung to the same USB drive.
3. Shut down PC
4. Unplug all your hard drives except for the Samsung F4 HD204UI 2TB Hard disk.
5. Boot PC and go to your bios. Select IDE mode for your Hard Disk if you were on AHCI.
6. Select USB Drive as your first boot.
7. Save and reboot.
8. After DOS boots from the USB drive, type HD204UI
9. It will start to flash your hard disk with the new firmware. Wait until it says finished.
10. Shut down PC
11. Plug all your other hard drives back.
12. Change your bios settings back to what they were, eg. AHCI back on if it was on before, change first boot drive which was your OS drive.
Cheers.
