anybody knows the life span of a CF Card?, how old is your oldest CF Card?

My oldest is a 64 MB Sandisk that I picked up just after Christmas '01.

It's, actually, the only one I have.. for now. :) Still going strong.

I've got one I'm about to pitch. I bought it about 6 months ago and it's totally crapped out. Takes FOREVER to get photos off it and I've lost more than I can count. I kept using it since I didn't know which disc was actually the crap one [I kept mixing them up].

It's a sandisk which must just be a lemon.

P.S. I use other cards that are up to 4-5 years old

None of my CF cards have given me any trouble. I have two 256's that are from when I bought my Canon G2, almost 3 years ago and 25,000 photos ago. Of course, my Canon G2 crapped out this August, but the memory cards are going strong in my new Rebel.

I did though buy a 1GB for the Rebel because I always hate to have to stop and change the cards, and I shoot Raw, which means 30 pics per card or so on the 256's.

Yeah, name-brand cards like Sandisk can last for years without problems. More generic brands use iffy flash memory that tends to cause corrupted files and other difficulties. I learned the hard way. :(

If the card is only 6 months old, you should be able to get a new one from Sandisk. It's certainly not normal for a card to fail that early, even in pretty severe use.
We have an industrial computer at work that some goof designed using a CF card as the boot drive, LOL. The cards are written to so often that they crap out after about a year. You can imagine how may write cycles they go through. I'm sure you haven't written to your card even one tenth a smany time as necessary to cause failure. I think it takes at least 100,000 writes, in the same location, to cause failure with moder flash memory (at least the high-quality memory used by makers like Sandisk.

I've read a similar stat about 100,000 writes per cell. I belive cards generally come with more cells than they need, so they can be swapped out to improve lifetime.

oh man! 64 meg on that s7000? how many shots do you get on the card, like 10?
there are some good deals on the sandisk cards right now. i hear you can get a 1gig for around 100 bux online.

my oldest CF is a sandisk 512, but it's only about 14 months old. it's still a baby :)
