Memory Cards: Erase, Don't Format

| 108 Comments

Memory Cards
When on the go, erase, don't format your memory cards...

After you've safely uploaded your digital images to your computer or other device, what do you do with the memory card? Here are a few tips:

  • Don't use the computer's software to erase your memory card; always use the camera. That way your card will remain as compatible as possible with your digicam.
  • When you're on the go and haven't had time to back up all of your pictures, use the "erase all" function on your digital camera. This allows you to recover deleted pictures with recovery software in an emergency.
  • You only need to use the "format" function on your camera every few months. This reformats the card completely providing you with a "clean slate," but also prevents data recovery in an emergency.

One of my favorite data recovery programs is PhotoRescue. It's available both for Windows and Mac OS X. You can download a trial version, and if you like it, purchase for $29.

Update: 11-10-2005 11am PST: After the discussion below, I retested on a Canon Digital Rebel XT and learned that I recovered almost as many pictures after formatting as I did using "erase all." The conversation below sets the record straight. Please read it, since it is more valuable than the original piece I wrote. -Derrick Story

I upload my photos to OS X and when I am done I format the card on the camera so that the invisible files (.DS_Store, Icon, etc...) that Mac OS X loads the card up with do not confuse the camera.

Also the format option on some cameras does not go as deep as you would expect.

I will often use my 1D MkII's lock feature to tag images I know I want to look at after I load them in Photo Mechanic. After I copy the images to my harddrive the originals are still locked. Rather than go back through and unlock then erase those images, it's much easier to just format the disk in-camera.

I use SanDisk's RescuePro and have definitely used it to save images from formated disks before.

I can't speak to point and shoots, but for pro-sumer and pro DSLR's formatting is a much easier way to clear a card. And as the previous poster notes, the .DS_Store and other files are good to get rid of as well.

I would disagree - I have had much more success recovering images off a card I have formatted than one where I "erased all." (Believe me, I've had both experiences!)

When you format, that actual files and data are still there, and are easy to detect and recover. When you erase all using your camera, it will actually go through and remove file data information, making it much more difficult to recover any images.

It is possibly true that formatting your card in-camera instead of from your computer may save you a little bit of trouble, it is still better all around to format your card in-camera than to use the erase all function.

I don't really know about the technology behind this stuff, but are you sure about what you've written about the "Format" function?

Just judging by time alone, I would guess you're incorrect. Write time on CF is pretty darn slow (as compared to read) and my Camera (Cannon Dig Reb XT) formats a card in just a couple seconds or so.

I guess I would expect that Format would just rewrite memory map of where all the files are located. That's what it means to reformat any other type of fixed-storage. That type of operation should leave all the files intact for "Rescue" like software to dig them up.

Please post a link to where you learned this information (or a retraction if you find that you're incorrect).

I've done some low level CF driver work and stepped through the code that does the formatting (Windows CE). Basically they rewrite the boot block (sector 0) and then zero out the fat table(s).

The data isn't overwritten unless a special option is invoked and that will take some time as it typically writes a sector at a time.

PhotoRescue is $29, but Exif Untrasher does the same and is freeware.

wrong...format only deletes the directory info. it would take quite a bit longer to write zeros across the drive. i personally always format in-camera after transferring the pictures.

Good conversation everyone, and I thank you all for chiming in. Here's the scoop:

I had an interview with Pierre Vandevenne of PhotoRescue. He said: "Overwritten data is of course lost forever, however, not yet
overwritten pictures can usually be recovered/reconstructed." I had tested this on an older digital camera and my conclusion was that formatting seemed to overwrite the files while erasing did not.

I just retested on a Canon Digital Rebel XT, as some of you had mentioned that you use. When I used PhotoRescue after "Erase All," I was able to recover 148 photos. I then formatted the card in camera and reran PhotoRescue and recovered 144 pictures.

So, those of you who stated that formatting in camera enables file recovery are right, at least with the Canon XT, and I would guess with most modern digicams. I should have retested on my most current cameras. My mistake.

Thanks for your help :)

The problem with erasing or erasing all I am told is that the camera actually does not delete everything. Over a period of time you can no longer get as many photos on the card and in theory you slow the access time down.

Please please tell me how do i recover pictures that i recently formatted by accident??
Im a bit stupid and didnt realise that format meant erase....is there a way, my memory card is Jessops

Dear Sir,
I was navigating the internet for the mentioned subject when I saw your article and something came up into my mind, that is every one now talks about recovering the data from the memory card if deleted by mistake but I found nothing about keeping our privacy if we delete something and we don't want any one by chance to spy us and break our privacy by recovering this data if he got our memory card or mobiles in away or another, so is there any safe way to remove the data from our memory cards without recovering it in future by any software?

With All Thanks and Best Regards,

does anyone know if I have any chance of saving photos from an sd card that I formatted on my casio ex z60?...I also accidentally took one photo after formatting, and then we mistakenly, when downloading recovery software, burned the installer demo on the sd card (!)...is there any hope?...I have tries a few software programs and they have not worked...thanks

Hi, i would try to recover the date with the recovery program from sandisk... i recovered a lot of data from my cards. My old d70 didnt like it if you remove the card if safing isnt finished so the file table was destroyed but with rescue pro from sandisk i recovered all my pictures...

Anyone that is not comfortable attempting recovery himself, can find several companies on the internet offering recovery services. Unlike most companies, especially the ones focusing on commercial customers, Rememory offers memory card recovery on a no cure no pay basis: you only pay for recovered photos. Feel free to send us an email for more details.

Does anyone know how long an SD card will *hold* image data for? Say for example, photos were taken a year ago, and since then the card has been formatted several times (by the camera) and many more photos have been stored on it, would it be possible to recover (even partially) using forensic tools the original photos that were taken a year back?

Exif Untrasher is freeware for MAC users. Is there freeware for Windows' users? I've tried Photo Recover by Art Plus and also Free Undelete but both haven't helped in recovering my photos on my digital camera. I clicked 'Erase' 'Format' by mistake!! Any advice would be greatly appreciated!!

Hi folks,

I use a TOMTOM sat.nav system and need to reload it onto my ipaQ, probgel is I cannot find anyway of removing the maps which are already on the SD128 that is part of the system. Without being able to cleanse the card I cannot load TOMTOM. Can anyone please help?

Hi, i have formatted my digicamera memory card many times and was just wondering if anyone can recommend any software which will actually recover pretty much everything, saw between 1000 and 2000 photos back, and probably atleast 10 formats inbetween.
I have a freeware program which actually recovered some very old photos aswell as the most recent ones, but not much inbetween. is there anything out there that is meticulously thorough...i assume there must be the technology for this. or is it just chance?
thanks a lot!

Following formatting my memory card on holiday (and seemingly to lose all the photos and video clips) I then went on to take another whole card full of photos and video clips. Does that mean that it is now impossible to recover the previously formatted photos and video clips? If that is so then I won’t spend the money on a fix -but if there is any hope then I will. My memory card is a ScanDisc 1.0GB

thanks once more

just one thing, can i post this entry on my blog? i will add the source and credit to your site.

Excellent post. First time reading your blog, but I'm hooked, and I signed up through Google Reader.

That is an enormously splendid article you have published there.

I formatted my Canon powershot SX12IS and lost all our vacation pics. I took it to the local photo shop and the used pc inspector software and and said they recovered no data. what can i do? I need to recover these photos or will be in a world of pain with my family.

There are many excellent freeware options for recovering photos. The problem is finding them. As this site doesn't allow links, just copy the following listing of freeware recovery software and paste it into Google to find them:
MiniTool, VAIOSoft, PC Inspector, Recuva, Pandora, SoftPerfect

I know this is very old, but this is complete nonsense. It's no more difficult to recover files after a format than it is after erase all. Please don't spread misinformation.
Formatting does not in any way securely erase the card. It simply re-initializes the file allocation table. The file data itself is left untouched.
There are lots of good reasons to reformat rather than erase all, not he least of which being the fact that it is much faster.
If you want to securely erase a card you need a special utility program which completely overwrites the card with random data.
