I've read somewhere that professional photographers prefer to format their memory cards before starting a new set, to minimise the chance of errors.
This seems like a good idea, especially when the number of photos becomes quite high. However, is there a limit to the number of formats an SD card will accept?
I do realise the CompactFlash type of media is more common for professional use. But there must be some semi-professionals out there who use SD?
I'm currently using an 150x Transcend 4Gb SD card.
