Make sure that you're on an account on windows that has administrative rights. If you're using a guest or secondary account, then you may not have "permissions" to delete certain things. Chances are this is not the case, but worth checking out.
Believe it or not, these cards have a lifecycle, much like a floppy disc or a jazz tape or even a cdrw. The become corrupt sooner or later due to the data being written, moved and deleted on and off the card itself. I've seen new cards die within a few months. I've also seen cards last for nearly 4 years. It's just the nature of the beast.
As far as deleting the files on it, you can remove everything that you need on it (make back up files) then try formatting the card. I've seen this work maybe 8 out of 10 times. I've also seen where it has formatted everything but the bad sectors of the card, and was still able to use the card (although I don't reccomend this because I've lost data that way!).
By reformatting the card, it will delete everything on it. If the card is corrupted beyond what reformatting can fix, then you'll have to replace the card.
If your camera (assuming that the SD card goes to a camera) has an option to format a SD card, then let the camera do it rather than having windows do it. If the SD card goes to an MP3 player or cell phone, try the same (let the hardware format the card). If not, than let windows format it, and try it in the camera (or whatever) again. If when you stick it in the camera (or whatever) and it says that the card is not formatted, would you like to format it now? Don't worry, say yes and let the camera (or whatever) reformat it again.
Hope this helps!
War produces veterans, wounded both physically and mentally. They have sacrificed for us.....and it is now our job to help these veterans, as they have already helped us in ways we will never know, in ways that we cannot fathom, and in ways that we take granted every day.
