I used my memory card in card reader to get some text files from my friend lappy. I did it two three times bt one day my lappy n my phn are having prblem with that memory card.......Whn i put it in my phn....it hangs n does not respond....as soon as i remove it frm phn, my phn says that preparing sd card.....whn i put it in lappy, my recognize it n says that there are problems with it, scan n fix bt it cant fix.....whn i open explorer it hangs....i tried formatting it using chkdsk n diskpart from cmd bt it also kind of hangs n as soon as i remove sd card from lappy cmd flashes message for commands written whn sd card was attached. Whn i used chkdsk h: /f on cmd it says that 'cannot open volume for direct access'......i hav also used tools like sdformatter n all, they all dont open till my sd card is attached to lappy....as soon as i remove my sd card they open n say no memory card attached............plz help me if there is a way to ormat my sd card or is it corrupted to an extent tht nthing cant be done? bt thn my lappy recognizes it...........hlpppp

Sorry to say, but this is almost always a failed disk/drive issue. Ive seen this happen with HDD/SSDs and USB drives. The only thing you can do now is replace it. Once it gets to that point there is no restoring it.
