I'm confused about formatting the CF card. When I want to format the CF card, I hit the two buttons with red format icons simultaneously, and hold them down until "for" flashes on the camera's top info panel.
People have looked at me like I was crazed when I did this while there were important images on the card. I thought nothing of it, since I knew from past expeince that doing this doesn't cause all the images to be erased.
But now I'm starting to think about this more. Isn't formatting supposed to in fact erase the card? My cards have never been erased by following this formatting procedure. In fact I erase my cards by choosing delete all in the menu and hitting ok.
Are there several format options--one that just formats the card and doesn't overwrite data (holding in those two red buttons on the top), and another format command, somewhere in the shooting menu, that wipes the card clean?
I've just taken it for granted that formatting doesn't wipe the card. But now I hear I'm wrong or something...or my camera is different than most.
Gee, I have unformatted hard disks and floppy disks to recover data, MicroSoft has a 'soft' or quick format, the '/Q' parameter, that writes recovery data but to use this recovery file there can be no write activity between the format and recovery. They has have an absolute hard format that does not write this hidden data. There also some programs that can do this, Active Uneraser.
I believe then in camera format is a form of erasing the data and with the recovery programs available from some vendors it could be possible to recover the data.
There are also data recovery services that can recover data from magnetic disk that be been rewritten. But CF cards are not magnetic media.
My D1 has been gone for a long time, so my memory is weak on this, but I thought the D1 used the same scheme as all the cameras that followed it, namely that you had to hold both buttons down for about two seconds until you saw "FOR" flash, then you had a couple seconds in which to release both buttons, and then push them both AGAIN to initiate a format. I wonder if you've actually been formatting your card at all, because you definitely should not have any photos showing up afterward.
This is correct. After initiating the format by holding down the 2 buttons (blinking 'FOR' on the top screen), you need to press the same 2 buttons AGAIN while the screen is still blinking to cause the formatting to begin. After the formatting is done, there will be no pictures left on the card.
If you goof, and format a card by mistake, you can use special software recovery to retrieve the data, as long as you haven't used the card after the formatting. If you have used the card, you will not be able to get any of the pictures back that have been overwritten by the new pictures on the card.
