UPDATE
On 18 November at around 21:00 (JST), when I started the update to version 1.1.2.0, I realised that a 2 GB HDD, which was exclusively for backing up Windows 10 ESU and Battlefield 6, was missing from both the Microsoft Explorer and the Disk Management partition map. I stopped the update and fixed the issue at BIOS boot. I know this hacker has a tendency to disable the BIOS boot remotely, but not this time.
Earlier this afternoon on November 18, I was playing "CASUAL BREAKTHROUGH MULTIPLAYER" of Battlefield 6 - 1.1.1.5, and it generated again a short beep 3 times.
Aside from that, when I restart Battlefield 6 - 1.1.2.0 update, the update speed slows down to between 0.10 and 0.50 Mbps, despite my internet speed being capable of 10 Gbps. I hope this is due to download congestion.
