| Does anyone know of a way to completely wipe a CF card after getting the pictures off of it. I don't want any trace of the pictures left on the card. Thanks. |

Destroy the card. I don't know for sure, but formatting a hard drive will still leave traces of the data. Formatting a CF card might do the same. Depends on how "gone" you want them.
Are talking top secret, alien conspiricy, or nudie pics? :)

even if you format the card the pictures are still on there and can be found with the right recovery software.
I think you can buy special software to do it though.
Or you could just shoot hundreds of pictures of "nothing" and they will eventually be the only pictures recoverable.
If you know what I mean.

| If you have Sandisk RescuePro you can wipe a CF card clean, formatting does NOT wipe the card clean, you can still recover files from the card with RescuePro after formatting the card. After wiping it clean with RescuePro you can't recover anything. |

| Thanks all for the info. And no...no Kiddie porn. A friend wants me to do an "unclothed" shoot of her, but I don't have a decent sized CF card. I would have to borrow one from someone else, and I would rather not send her photos around. That would be entirely up to her to do. :) |

| As i understand it, there is a chiop in a CF card that distributes the writing to different areas each time, becuase the card itself can only be used so manytimes (1,000 or more so no need to worry). So unless you shoot and fill the card the erased files are likely still there quite intact. |

Have her buy a card (or split the cost), and give it to her when you're done. |

I'm still not convinced that this girl you speak isn't 13 years old! |

In this case, as a precaution you should send the files to me first, and I'll see to it that they're properly discarded :) |

| Thanks for all the kind offers of checking and clearing the card for me. I don't think she will go for that. :) I've already told her that I'll be sure and delete them all from my computer. She didn't buy it either! LOL And yes, she is 24, not 13! |

A compactflash card uses a FAT32 filesystem.
Formatting a card clears a table in the beginning of the card. It doesn't destroy data.
To destroy the data on the card the best thing to do is to write alternating bits (1's and 0's) to the entire device (the device, not the filesystem).
There are some tools that will do that for you.
Here are two simple methods:
1 - Format the card and copy other pictures or files to the card until it's full.
Repeat this 3 times with different files, then do a final format. They will be able to recover they files you copied, not the original
2 - Open a picture you have in notepad. Copy the contents. Open each picture on the card in notepad. Paste the contents. Save. This will overwrite the specific blocks that are occupied with your photo. (step 1 is probably easier and will be more successful)
Once you've done this the majority of usable data is destroyed.

Format. Shoot junk to fill it up. Format again.
Do it 2-3 times. If you paranoid do it 5-6 times.

There are lots of freeware programs available that will scrub a drive clean -- absolutely clean to the military standard which includes, if memory serves, overwriting the erased data area seven times with random numbers sequences. If you use a card reader, or your camera shows up as a drive when cabled to your computer, one of these programs will do the job nicely. You will likely have to format the card again after this scrubbing in order for it to work in your camera.

| Easiest thing to do would be after you have downloaded your photos, format the card and just fill the card with snapshots of anything, that way it will wipe over previous information and it can't be salvaged! If someone DOES try and salvage what is on there all they will find is your quicky snapshots! :) |

You can borrow my card, I will get rid of the evidence. As long as they are of legal age, and they are not a man.

I like Pretty Good Privacy - PGP. Freeware versions at //www.optikvervelabs.com/default.asp
This will wipe a drive or card clean so no-one can tell what was there before. I mainly use on of its other features, it allows you to make a virtual drive that is password protected, and virtually impossible to get into without the password. This means you can save your pics on your harddrive or a CD and no-one else can access them unless you give them the password.
Not sure of its legal status in the US currently, it was illegal in the US at one point because the military couldn't crack the encryption in a reasonable length of time! Always OK here in the land of OZ though. |

| Ya know, I'm thinking the best thing to do is just break down and buy a bigger card myself. That way I don't have to borrow one and I know it will always be in my hands. It's not like I couldn't use it anyway. Sorry Travis99! LOL |
