Having a problem getting computer to recognize a particular micro SD card in laptop. Card must be used with SD adapter. Have many cards and a couple adapters. All cards work with both adapters except this one card. This card does however work with no problems in HTC 6800 (Sprint Mogule) Windows Mobile 6 phone. The card also does not work in a digital camera. The card previously worked in all 3 devices until recently. Don't know what could have happened to the card or why it is not being recognized. Believe it stoped being recognized while in the digital camera. Would expect card to be bad but works fine in phone. I have insepcted card and find no apparent size differences for a loose connection, no scrape or corrosion on pins, etc. When inserted in computer there is not even an attempt for the computer to read the device as if it was not there at all.
1) what would cause the card to work flawlessly and all of a sudden stop working?
2) could there be a lock mechanism software or hardware that would cause the device not to be recognized?
3) is there any resolve to this as this is my largest SD card and I would like to continue to use it?
Please read question again before asking to repeat scenario. Thank you in advance.

I have not tried reformatting in camera yet. currently have the card in mobile phone (which still works fine) downloading all data from card via USB sync cable and will try any recommended solutions once finished. do you recommend reformatting in camera or phone? remember computer won't read at all or give option to format.
yeah.. you need to reformat the card in the device you'll be using.. remember the old floppy disc days when a formatted disc wouldnt work in other drives.. just depends on their particular encoding / redaing method employed on the particular card as to whether it'll work or not.. you'll probably find that after you've formatted it in your camera it'll still work in your phone etc etc..
could not figure out how to format card using phone, so tried to reformat with camera. as soon as card was placed in camera it was able to read it again (weird). I also cannot figure out how to use the camera to reformat the SD card. So now the only problem is what I originally began with. Card is still not recognized in XP computers (tried 2 now) and I need to be able to transfer files back and forth between phone, camera and computer and a USB sync cable is not always available. Ex: to email pictures taken on camera or to put music on card to be played in phone as MP3 player. Any more ideas?
response to Periwinkle: Yes, the full sized SD card (adapter) has a sliding lock on left hand side. This however only makes the card write protected for as far as I can tell and does not appear to affect the computer's ability to recognize the cards. Other cards are recognized with this slide in either position. This card is not recognized either way.
response to PsychoFelix: brand of card is SanDisk, marketed as compatable with all units. This is even the more expensive card rated for HD. Not that I am stuck on SanDisk, but this exact card worked fine in all of these devices for about 3 months before it stopped being recognized.
response to periwinkle: I have not yet tried checking w/the manufacturer, will do that tomorrow, thanks.

Did you by any chance open the card hatch and remove the card without turning off the camera? That is one of the primary reasons I'm aware of for card corruption.
I believe that there may be a lock mechanism - my card (new camera, new media) is currently downloading images - I'll check shortly to see if I can identify it.
