1-Have you ever had a card failure?
No.

2-What size card resides in the camera?
2-8GB, various brands and speeds

3-Do you download with a card reader or the camera tethered?
Card reader usually, but sometimes tethered to an 80GB portable storage unit if I'm traveling.

4-Do you delete all pics or reformat after downloading?
Reformat after download and backup.

5-How many frames has the card seen?
Unknown. I have about eight cards and 20,000+ total exposures on my two a100s.

I have had a few JPEG corruptions (I shoot RAW+JPEG so this was not a major issue) and one RAW file corruption. All were early on and could have been the result of removing the cards with power on (yes, I was guilty of doing that for a while!). I didn't discover the RAW file corruption until recently when I was converting to DNG.

I have to say that on average I did much worse over the years (losing images) with film.

I've never had a card failure (I own 4 memory cards - 2@4gb and 2@2gb - Lexar and Sandisk) - I have probably reformatted them 300-500 times? I rarely fill the 4gb's - bought them because I was filling the 2gb's fairly regularly - since I replaced my 7d's with A700's. I only shoot raw so I get 203/208 frames on my 4gb cards respectively. For trips, I bought a JOBO hard drive storage/display device instead of purchasing more cards - works like a charm!

I started reading this thread without realizing the date it was first created. I was all ready formulating a response in my head, when I saw my post from 2.5 years ago. I was exactly the same as I was going to say today.

But since then, I have got more cards, bigger sizes, the same still holds. Yet to have a card failure.

Stick with top brand cards, always format in camera, and life is good.

1-Have you ever had a card failure?
    nope

2-What size card resides in the camera?
    -32 GB transcend CF, 8 GB sony MS PRO DUO

3-Do you download with a card reader or the camera tethered?
    Card reader 100% of the time

4-Do you delete all pics or reformat after downloading?
    Usually just delete, occasionally format

5-How many frames has the card seen?
    No idea.

I've owned 8-10 CF cards, many of them cheap generics, and have never had one fail. For that matter I've never had any problems with any solid state drives, including the card in my phone, my computer's SSD, god knows how many USB flash drives, SD cards for point and shoots, etc. I will actually trust a cheap USB flash drive for retaining non-corrupt files more than I would a standard HDD.

1-Have you ever had a card failure? Yes
2-What size card resides in the camera? 8GB Apacer. The vendor offered to replace it but I declined the offer and switched to 16GB Sandisk. The 16GB was the only Sandisk they had left, I would have prefer an 8GB card.
3-Do you download with a card reader or the camera tethered? Card reader
4-Do you delete all pics or reformat after downloading? Mostly delete, at odd times, I'll format
5-How many frames has the card seen? Less than 100

Look back at some of the replies on this 2007 thread, I am pretty sure that there have been much design improvements in chip designs. My spanking new Apacer failed last year... corrupted files, so I'm a little disappointed. I have a 8GB Kingston as a X'mas gift last year but it sits unopened in my dry-box. Should I trust it?

Another question is... I noticed most of you folks format your card. Does it make any difference between formatting and deleting the files on the card?

Yes it does, and I was about to comment on that as I was reading your reply. Formatting the card is the only way to truly reset it to zero so to speak. Formatting removes all data from the card where deleting pics one at a time doesn't.
And a note to be sure to format with the camera and not the computer, if you do it on the computer you could reset the card's protocol without realizing it and then the camera won't recognize the card.

Do you know for sure that formatting deletes all the blocks of data? It can be achived by merely deleting the able of contents - and I suspect is what happens as it is quite fast. A full format can take considerable time.

I assume by "ressetting the card's protocol" you mean FAT32 file format vs NTFS? I *think* most cameras expect FAT32 format. You can choose what file format to use within most recent versions of MS Windows.

I've recovered data off an accidentally formatted so I'd say no. It probably just resets the Master File Table. I still format cards rather than delete though.

I was on another forum recently and one photographer was complaining about his failed Kingston card after 4 uses and his experiences on his warranty claims. It's interesting to know that Kingston USA claims their cards are not designed for dSLRs.

Do I have another clay pigeon in my dry-box?

I have another question regarding formatting the cards as to deleting the files on camera.

How does that effect the card? Does it mean that new images written on a newly formatted card are digitally cleaner or the action serves to allow faster files writes/ transfers to the card or PC?
