When I put my 2gb SD card in the drive on my computer it reads it but is unable to bring anything up because the computer says it is unformatted. I have tried to reformat using the FAT16 and FAT ways but neither have been successful. It says that the format was unable to be completed. Does anyone know what I should do to fix it?

You can't format a partition that large using FAT or FAT16. Try FAT32. FAT16 doesn't support long file names anyway. If you are formatting for use in a camera then insert in the camera and format it from there by using a USB cable.

OtheHill FYI All my 2GB SD cards are formatted under FAT16 (camera default). I've always heed what M$ stated in this article: Most digital cameras expect the storage media inserted to be formatted to the FAT16 specification (or FAT12 for low capacity cards). With all but the lowest capacity CompactFlash and other card types, the Format function in Windows XP defaults to the newer FAT32. While newer is often better, a FAT32-formatted card will actually be incompatible with most digital cameras. To avoid FAT32-formatting your cards accidentally, or to fix a card that has already been incorrectly formatted, choose FAT from the File system popup menu in the Format dialog before running the format function. Windows XP will automatically select FAT12 or FAT16 formatting, depending on the capacity of the card. There are exceptions to this rule. Specifically, if your card has a capacity greater than 2GB, and your camera is one of the rare models that supports FAT32 (newer Kodak DCS models are compatible), then FAT32 format the card to realize its full capacity. i_Xp/VistaUser

Further to above post, I always format SD memory cards from the camera by using its built-in Format utility, never in Windows. I guess this is what guaranteed my trouble-free experience with using the same SDs over and over and over again after so many quick format. i_Xp/VistaUser

XPUser Isn't that what I said in my original post. "If you are formatting for use in a camera then insert in the camera and format it from there by using a USB cable".

Duh I missed it but I never use USB cable to format the SD. Every camera has its own built-in format utility. i_Xp/VistaUser

I just checked and I was wrong about the drive size limit. It is 2GB give or take for FAT16. May be an issue with the capabilities of WinXP.
