Can you damage a memory card from formatting it to often?

As the title ask: Can you damage a memory card from formatting it to often?  I've been doing it after every download and was told today that I can mess up my card by doing this. 

I've done some searches and frankly can't see where this is true.  I'm asking here just to play it safe.

If that were a fact, I'd probably be tossing my cards out today. I format every time I make a move with the card, after moving files to the computer, or even inserting a new card in camera. The cards will go obsolete before you damage them. Ignore the clueless!....:unsure:

Why so serious?

Glad to see you don't do harm as I format my cards ever time too.  Well most of the time.

All cards have lifespans, but you would don't have anything to worry about as the max read/write figures are beyond what you are likely to do... BTW, judging from your avatar, you are a fellow Georgian ?

Actually it is worse for your card if you just use the delete all over formatting. Deleting can still leave remnants of the old data in the sectors. This in my opinion is why people get corrupted photos eventually. Formatting clears for a clean over write every time. I never delete, I only format, even when I know I screwed up a photo in the field. It is also why I carry extra cards when my old one is near full.

I'm not sure where you got this impression, but that's not necessarily correct. Formatting, in most cases, does not zero out the media. It simple rebuilds the data structures necessary for the filesystem. You have just as much likelihood of having stale data on the card.

When formatting drives in Windows, you have the choice of format or a "quick format". The latter does what I have described. A full format will clean the disk.

My Nikon formats every size card almost immediately; I'm pretty sure it's not scribbling over the entire card.

It is safe to say that rebuilding the filesystem is a Good Thing and can repair any incremental damage that may have occurred on the card. At least you know you're starting from a good state. But that doesn't mean the card, as a whole, has been vetted.

I accidentally washed one of my SD cards and after it dried, it still worked!
