SD card wont mount on phone and PC(via USB) aswell

(my phone SE Xperia Mini Pro) So i rooted my phone, made 2 partitions, becaus i wanted to move apps to my sd card, so everything went well, i did everything as said here-->"had to remove the link becaus its my "first post"," anyways i didnt figure out how to move my apps, so i messed around with my phone all the time and in the end it wont mount on my pc. i connected via usb-nothing happens, checked in the phone SD card info and where it should show size, it showed not aviable like there would be no sd card in the phone, then i took out the sd, puted it in adapter and connected to pc-still nothing, and while writing this thread the phone ike restarted itself. I hope someone can help me, im waiting for reply.

Edit. Now i tried to connect with adapter and SD card finaly connected and i could open it and see the files in it, but still nothing while being held in [hone or connected via usb

 

Thanks for the reply.

Still nothing, i updated my sony ericsson Pc companion, and as it seems the companion can'd detect my phone, it has connection but cant detect it, when i plug out usb and then again in it kinda detects the phone, but no signs of connection with pc in the phone screen, it's only charging, but its acting like there would be no SD card. Might that be possible that i skrewd up my Sd card in any way?

 

I have tried to do that lot's of times, still nothing.

 

finally i got the sd card connected via adapter. i just changed the phone settings to factory defaults but anyway's phone still won't read it.
Now when i connected it my first tought was to deleated partitions so i can get new,clean sd card, but when i opened "Minitool Partition Wizard" it said that my sd card was "Bad Disc" and i can't change anything.

 

ok, i would be very thankful if you could give me a tutorial, becaus it has got really messy, so it would be great ir you could do that

 

Everything would be great if i could figure out a way how to connect the card to pc, last time got it connected was right after i deleated all data on phone-just puted on the factory settings, the default settings, but i did it a few minutes ago and it didnt work. Just cant figure out how to connect the card to pc
