Well that's debateable and kinda like the question 'should I use a lens filter?' and is discussed in this very thread. Start over on page 1 for more info and POV's.

I see your point. I posted the question because if formatting the card makes a difference, I will adopt the habit but since that practice is debatable... I see no reason to change my current habit at the moment. Thanks for clearing up the fog.

I have never experienced any memory card failure. I have SanDisk CF cards in 8GB and 16GB sizes. I have Sony brand Memory Sticks in 4G, 8GB and 16GB sizes. I purchase no other brands of memory cards.

My memory problems have all been with my A700. Both types of memory card sockets failed. The CF socket failed within less than a year of purchase. The memory stick socket failed within about two years of purchase. This latter failure required replacement of 700's main board because the memory stick socket is directly soldered onto the main board. This latter repair cost me approximately half the new A700 purchase price.

Out of curiosity, I asked the repair service what happens to main boards when they fail. I was told that they are repaired and recycled. But I was required to purchase a NEW main board because the memory stick socket developed a mechanical, not an electronic, failure! That is what I was informed. I am not absolutely certain that I was not sold a recycled main board.

I transfer picture data into computers via card readers and via direct cable connections between the cameras and the computers. Both methods appear to perform well.

I normally erase picture files by reformatting the memory cards in the cameras. I NEVER erase picture files or format memory cards in the computers.

I purchase only new memory cards from well known dealers.

The only memory card I've had fail was in a phone, and it came that way.

I generally take the card out and put it in the computer these days, download all the pictures, delete them, reformat the card in the camera.

I've adopted these steps cause I'm lazy, I've left the camera running plugged into the computer too often and found dead batteries, found myself with multiple duplicated photos cause I downloaded them multiple time (not deleted from the card) and generally forget to reformat the card when I put it back in the camera.

Most of my cards are sandisk. And I suppose that putting it in the computer and formatting with block checking on occasion might be a good idea, to see it there are any errors, but I'm sure I would be way too absent minded to remember to do that. And I find the claims that reformatting in the camera will increase performance pretty easy to believe, having worked in system administration type jobs for 20 years.

The CF card has vulnerable pins. Careless insertion or an inappropriate card slot can lead to a bent pin(s). The camera slot is deep and has long guide 'rails' however, the compact card readers often have very shallow slots with inadequate guidance hence extreme care must be used when inserting a card. The slightly larger readers are better. I have had one bent pin which I straightened with pliers then inserted it into a deep slot in a reader to complete the straightening. No more problems!

It is worth remembering that a card "reader" is no more than an interface between card and computer. It doesn't 'read' data: it allows the computer to do so! If data is corrupted, then don't blame the reader - blame the computer!

I had one complete CF Card failure which was accounted for because I had tried to use that card for MS's Ready Boost. This overwrote must of the card's memory and would not allow it to be used again in the camera. I recovered it by using the computer to fill the card with copies of photo files to overwtite the 'ready boost' area. When it was reformatted it worked correctly, but failed completely some time later.

It may be worth while to identify each card you use and to keep a record of exactly what it was used for. The idea of using one card - one device is sound.

I use only Sandisk, download images using a media adapter/reader in my computer and reformat the cards in the camera after each download.

No problems after many years of service.

I'm not sure any debate is warranted, at least with recent Sony cameras. My reasoning is:

1. If you have only a few files to delete but want to keep other files on the card for the time being, then delete only the few files. For still files, this can be done either in-camera or with a computer. However, with movie files, you had better do this in-camera. Sony's movie files are tied to a bunch of other files that should be updated following a deletion.

2. When you're done with all files on the card, format it. Why wouldn't you want to do this? It doesn't take any more time. And you should do it in-camera because, as mentioned, Sony requires a number of subfolders and files to be present on the card. If you format the card in a computer first, the camera will have to build that folder and file structure anyway.

3. Every once in a while it could be a good idea to full format (not quick format) the card using a computer - especially if the card has already misbehaved in some way. The full format exercises and refreshes more of the data areas, so it might correct, or at least identify, any problems. That's why a full format takes much longer.

i have several memory cards from different manufacturers, the only issues i have had were with an adata 16 gb card, it would loose one raw file every time i shot with it, so i dont use it. right now i have 2 32gb 433x transcend cards, i have had no issues with them. I understand the multiple card issue, and if you are a pro, shooting high end on site shots, I would probably agree. I am not a pro, i do shot some on site stuff, but since i have not had an issue with the cards I use, I have not worried about it. For me, a large card allows me to not have to worry about changing cards often, and if i go on vacation, i will usually download them every night.

I am not sure what you are referring to??? The CF card has no pins, they are in the reader/camera. The same caution applies though, the pins in readers, especially, are vulnerable.

I have had one 16GB Sandisk failure. They replaced the card.
C & C always welcome,

Most of my CF, SD and MS cards are Sandisk. I download with my computer's built in card reader and format the cards in the camera. I use 4GB or 8GB MS in the second slot of the camera for backup. I have switched cards from one camera to another; when I buy a bigger capacity card it goes in the higher resolution camera, and it's card moves down to another camera. I've never had a problem with any of my cards but, I did purchase a Sandisk Extreme III 4 GB CF card from Best Buy that was DOA.

I've never had any problems with CF cards. I've even washed & dried one in my pants pocket and it still works.

Most of mine are Lexar and they are faultless for me. Actually have never had any problems with Lexar, Sandisk or Kingston which are the 3 brands I use.

The only CF card failure I experienced was in a card I had purchased new on eBay from what looked like a reputable dealer.
However, I subsequently found that it was a fake, and lost images taken with it - they looked OK on the back screen of my a700 at the time I shot them, but when I downloaded onto the computer there were some missing parts of images and interference patterns across others.
Here is a link to a comprehensive illustrated guide to picking fake CF cards: http://reviews.ebay.com.au/FAKE-SanDisk-Extreme-Compact-Flash-Cards-Exposed_W0QQugidZ10000000001449653
And a similar guide to picking fake Memory Sticks: http://reviews.ebay.com.au/FAKE-Sony-Memory-Stick-Pro-Duo-MagicGate-Cards-Exposed_W0QQugidZ10000000001535703.
When I identified the CF card I bought as a fake, I reported to eBay and got my money back, but did lose images, and as others have said here, only get your memory cards from reliable sources. The fakes look very like the real thing until you check the fine details against those links above.
