Thread: My SD card not detected by phone

HI,
I am in gr8 trouble as my SD card is not been detected by my HTC 3400. I bought it more than 1 year back, when it was working fine, but now after having some problems with my device, it is not detecting tha card at all. The very strange thing that it is detected by all other phones & Laptops, but only not by mine..so the card is OK. And also my phone can detect MMC card very well. I tried with many ways to sort it out but in vain..
As far as my phone problem was there, it was of earphone, & that was sorted out, That time I kept my mobile for servicing, but did not serviced as told for MB problem, but then is was automaticaly sorted out.
I don't want to shift to MMC card due to its limitations, even as I am using it now only 128 MB which I was havingg with me.
Pl help me for this problem. I hope there must be the expert or experience person for this kind of problem.
