An external non dedicated flash will register as 'flash did not fire' even if it did.

I know I was addressing a different post, I should have quoted to put it in context. I expect the flash never fired cos there was sufficient light at iso6400
Perhaps someone had been playing with the camera and changed stuff. I've had that happen.
Going back to the photo and settings. We all make mistakes and it is easy to press a function button and change something inadvertently. The exposure compensation on my NEX5 is very easy to hit resulting in photos over or under exposed. I don't know of any manufacturer who puts a 'button lock' on their cameras (like they do on phones)

I don't know about other manufacturers but the Canon 1 series require the use of 2 buttons to change anything, making accidental changes nigh on impossible.

Nah, I had an A55. There's no way someone could accidentally set their ISO to 6400. You'd have to press the menu button, scroll down to ISO, press OK then scroll down to 6400 and press OK again.
Given the A55 is SLT, the menus would be slap bang in the middle of the EVF making it impossible to miss.
What I suspect has happened is OP has attached the flash. It hasn't registered and looking through the EVF she has noticed the underexposure. So has bumped up ISO without really noticing the flash wasn't firing.
The A55 is actually quite a good little performer up to about 1600. 3200 at a push with some PP tweaking. It sucks eggs though at 6400.
Pure operator error through lack of knowledge I'm afraid.

In a situation like this where the ceiling is too high, would it help to use a diffuser and point straight at the subject?
Or a white card attached to the flash to direct the light towards the subject?
The only reason I'm asking are that I've been using my flash in front of a well lit window the the photograph still tends to come out dark. I've just exposure compensation which helps a little.
Should I lean towards spot metering on the subject or keep it at evaluative metering?
Cheers

Simple answer - yes. If the room really is too big to bounce off anything [though you would be amazed how much the more powerful flash heads can out put and get bounce back on] then some kind of bounce card or diffuser will help. Try looking up Diffuse-it or DembFlip for hinged ones that allow some flexibility on the amount of light bounced back, or a simple piece of white or silver stuff [that funny foam rubber stuff you get in modeling shops seems popular but cant recall what its called] wrapped round the head with an elastic band can do the job. this way you point the flash ceilingward, and let the card do the work
