You need new battery.

What are the settings for the Canon 580eEX-2 when using the Turbo SC?

If you have the camera on continuous then it may be that the charging is not keeping up with the shutter. Check the recycle time on the flash and compare with the burst speed on the camera. The burst speed on the 5D is fairly rapid.

as I stated in my first thread , no firmware or drivers
needed for internal HDD , and remember Windows
uses an allocated partition of 8 gigabytes for the OS
which will only leave 5 gigabytes left on a 13 gigabyte
HDD , and for solid state HDD , the only difference is
solid state has no moving parts , there are trying to impress us with technology that is over 35 yrs old
like a calculator other than its buttons its solid state

you have a bad bulb on the left side could be front or rear thats what they do when a bulb is bad

Load 4AA with Energizer Lithium Batteries.
Set 580EX II's function to 12-0 and 05-0.
Make sure 5D's is not set to HSS.
No white dome parked on flash.
No bounce.
Set camera to "M" with max sync if you like, but 60 is fine.
Set F-Stop no greater than F5.6
Set ASA/ISO no lower than 200 but not over 1000.
