Respected Members,
I am in huge trouble...plz help me
I have recently changed my android device..i used my old phone micro sd card of 64GB for new mobile set...but soon i was not able to see contents in my phone...not photos,documents etc...
When connected to netbook (windows 7,64 Bit),i got message that you need to format drisk F..when tried that option got a message that window is unable to format the disk as it is WRITE PROTECTED.

I googled all the options to remove write protection but i failed..i used all softwares like
1) EaseUS data recovery
2) HDD low level format tool
3) Steller data recovery
4) icare data recovery
5) M3 data recovery
6) CMD command diskpar....,even change registry WriteProtect to 0 as my netbook is of 64bit so changed registry in QWORD VALUE
7) checked lock on card adapter

I means,all the options i used then also i was not able to remove write protection..
I have very imp study material in it...
So plz plz help me

 

Put the card back in your old phone and then copy important information from there.
