I think you're pushing your luck with only one card.

I have a couple of cards but because I have two different brand cameras, I don't switch cards between them.

What's the purpose of a low level format?

According to Canon, "Do low-level formatting if the card's recording or reading speed seems slow."

According to articles I've read in the past, low-level formatting erases all recordable sectors in the SD card.

How long does it take when you do a low level format?

I have a 16 GB card. Half full, it takes about 10-12 seconds as opposed to less than 5 seconds for a standard format.

That is not a low level format. Sure, that's what Canon is calling it but there is no way the camera is doing an actual low level format in 10 -12 seconds.

I wonder why they would choose that term to describe something it's not doing.
