Error Codes

From Free60

[edit] General Information

E 64 : Unknown

E 66 : The key of the DVD drive firmware doesn't match the key of the motherboard.

E 68 : HDD Failed to initialize.

E 74 : "according to Dennis Mooney (Xbox ATG) on the 360 dev forums E 74 is HSIO Calibration failed" (HSIO is that insanely fast bus between the EDRAM and the Xenos core. It needs to be "trained" to be reliable.)

E 79 : Unknown

[edit] Confirmed facts

When the Xbox crashes half way loading a game disc (e.g. Due to bad unreadable sectors half way)

• It halts itself to a freeze : The Screen which was active, remains.
• eject does not do anything
• USB Devices are no longer working
• Wireless Controller does not connect
• Plugging in a USB Controler only lights up Left Corner, and Right Down Corner
• Unconnected Video Out Cable results in red flash, Reconnecting removes red light
• The only way to get your box back is to unplug the power cable

[edit] Speculation

Error 79 has been known during obvious signs of graphic corruption. (Overheating?, Power supply insufficient?)

• Error 79 can occur if the Xbox 360 firmware is corrupt.
• Error 74 can be fixed by disconnecting and reconnecting the hard drive. This would be in contrast to the Dennis-Mooney-Quote.
