Ever had a truncated file?
I was just finishing off some shots for a client and I renamed them to fit in with some previous work I'd done for them, sent off a small jpeg for approval and got an email back saying they couldn't open them, when I tried I got a message in Photoshop saying the files were 'truncated or damaged', so were the renamed tiffs, couldn't open the jpegs but I could open the tiffs and found the image had been split in half and lost a colour channel.
Luckily for me I always save original edits under the original file name to two external hard drives, which I re-opened renamed and saved again, this time it all worked fine but it makes me wonder why are computers such a PITA sometimes.
Just a reminder to everyone to never rename an original, this got me searching on the internet to find out why it happened, I couldn't find an answer but did find that once 'truncated' the file is gone forever!
