Space on 8GB card? I bought two of these, and I have one on the way. (Transcend 8 GB SDHC Class 6 Flash Memory Card).. My question is this- One of the ones I got has a 7.31GB capacity, the other one is 7.46GB capacity. I realize that sometimes the formatting takes up some space, I did not realize it would be different from card to card though, or take up that much space. I wonder what my third one will be?
What capacity are other people seeing?

You're not losing all that space to any "formatting", you're just prey to marketing and confusing computer lingo. Hard drive manufacturers dictate a 1GB as 1,000,000,000,000 bytes whereas Windows calculates 1GB it as 1,073,741,824. Technically speaking, windows version of GB really should be referred to as GiB rather than GB. A 500GB hard drive sold by Maxtor/WD/Seagate etc. will show in windows as 465.5 GB. Just as these 8GB cards show as 7.44GB. For simplifying, you can pretty much divide the stated capacity by 1.074 to see what you're actually going to get.
Formatting a Flash Drive (like formatting a hard drive on a PC) does two things: (1) removes the index to all files and (2) removes references to bad sectors. In all likelihood, this is why one of the memory cards reports a smaller size
Morlok says: "I never gave it much thought so I checked mine. I have an 8GB Kingston elite pro card which actually has a 7.49GB capacity."
Yup, that makes sense. I checked out my third one and it has the same as the other one, 7.46GB- so it must just be the space needed to format. It must be like regular Fat32 HD in a PC, (or NTFS for that matter), they both take up quite a bit of space just for the format.
