By device manager at the very least. It does not and never needs to be formatted so let's clear up if it shows in device manager or not.

I can't tell if this is that 32GB card issue you encounter on Windows XP.
My SDHC card lost its formatting when I was trying to download photos from a trip to Thailand (so very valuable to me). I tried several photo recovery programs and they did not work because my computer would not see the card due to lost formatting. An error message said must format card first - which of course I did not do.
I next tried two format recovery programs, ICare Format Recovery and Mini Tool Power Data Recovery, and they were able to find some jpegs on the corrupted card. But none of the viewing programs I try will open the jpegs! I tried Windows photo viewer, Picasa, Paint.net, nothing sees them! What should I try next - a different recovery program, or something to make the jpegs readable (what?)? Thanks!
