Removing SD Card while Titan is on?

[maxavius]

Hey guys, a quick question. I've always been concerned with removing my SD card from my Titan. I usually always shut off the phone which is a pain in the butt then popping out the card. is this necessary? Can I just remove it while the Titan is on?
I don't know about you guys but I have quite a few files in there and I would really be beyond pissed if the card was unreadable after. I've had this happen to my other cell phones (non PPC) and have lost mainly pics but never the less, that's where my concern is.

Appreciate the help,
