That is what I am afraid of also. But, I have been wrong before, and many times after.
After reading a bit, it might be possible. Be worth a try for sure.
Don't listen to him, he doesn't know the difference between a quick format and a full format, and didn't read the post by OP at all
And with a 40d, you can't do a full format, so there's absolutely no problem.
To explain the situation better, read the next section carefully:
A quick format is an overwrite of the file allocation table for the storage device, when talking about FAT16 and FAT32 (SD cards are FAT16, SDHC is FAT32, CF cards under 4GB for CF can be FAT16, the rest must be FAT32, though most CF cards are FAT32 regardless) file systems. The data that was on the card is unchanged, except for the file table. The file table acts like an index in a book, telling you where everything is. If you get rid of it, you can't just skip to the correct sections, so you need to search starting from page 1 and continue from there. As long as your sections (files) are continuous, recovering it is easy. This is why formatting the card after use is a good thing, because it lets you write files continuously. It takes a long time to copy the information if the file table is gone, but it's not that hard, and usually you get back >95% of the files.
A full format takes it all one step further. Instead of just re-writing the file table, it also returns all of the contents of the drive to nothing (all 0s), then makes a new table. This causes all of the files to be deleted permenantly (though some advanced techniques can still recover some files, though these tend to be very expensive). However, to do a full format you need to write information to the card, and even on a 15mb/s card (like ultra ii 2008 edition), it'll take about a minute per GB of card space. In the case of OP, he said it took only 5-10 seconds, so this is clearly not a full format.
I don't hate macs or OSX, I hate people and statements that portray them as better than anything else. Macs are A solution, not THE solution. Get a good desktop i7 with Windows 7 and come tell me that sucks for photo or video editing.
