CCP Director, Dr. Erlendur S. Thorsteinsson, posted a full disclosure regarding the recent Trinity Patch incident, in which the patcher deleted BOOT.INI file from the system. Thorsteinsson explained how and why the fatal mistake happened in detail:
Shortly after releasing EVE Online: Trinity at 22:04 GMT on Wednesday, 5 December, we started receiving reports that the Classic to Premium graphics content upgrade was causing problems to players by deleting the file C:boot.ini, which is a Windows system startup file. In some cases the computer was not able to recover on the next startup and would not start until the file had been fixed. In this dev blog I want to tell you how this happened.
In the weeks leading up to the release of Trinity, one of our concerns was how to deliver this update to our players in a very short amount of time and to players that might not all have a good internet connection. Significant effort was therefore put into making the Classic to Premium graphics content upgrade as small as possible at various stages in the process.
