HI, I recently tried to install w7 by using a usbdrive (while reading a tutorial on a website ) that asked me to follow some diskpart commands in commandprompt, i followed those and later i realized i forgot to plug my pendrive! and after i had typed few commands frm that tute i realizd that two of my hard drives frm "my computer" had disappeared, and only two remained , pls help me in getting those two drives back.
