Welcome to the forums!
Sorry it's under such troubled circumstances, but many of us joined that way, so you're in the right place.
Maybe it's a small problem that's easily fixed - although, whenever they happen, they always feel like they're complex (I sure know that one, myself).
So - how about some more info?
When you say you just got this - are you referring to your Incredible or a new SD card? If you meant the Incredible - did you get it new? If you meant the SD card, please say size, brand, and where purchased (oddly - that's very important, trust me).
When you say the SD card works in your old phone - what kind of phone would that be?
And just to be kinda complete - have you moved the SD card into a computer or printer, and/or have you had your Incredible connected to a PC/Mac/Linux via the USB? (Not saying to do those things - just asking IF.)
Maybe with some more background, we can zero in on this one.
As an encouragement, I've seen beaucoup SD problem posts and only the rare few that aren't solvable.
