Greetings and a Happy New Year! I am a new Mac user, so please forgive me for any nomenclature mishaps. Still working on understanding the Mac OS. I am using a Macbook Pro 15", late 2011, latest version of Lion I recently upgraded to a SSD for my boot drive. The installation was successful and I was able to boot and work from the SSD and the standard HDD just fine. The applications are and boot data is on the SSD and my User data is on the old HDD. I linked it up this way via preferences, as was the procedure I found online. BUT I changed the name of the HDD after I linked up the pathway. I neglected (read idiotically forgot) to modify the pathway via preferences. Now upon boot, the OS can't find the USER data. My thought is to somehow change the HDD volume back to the old volume name and everything should be golden. I can boot up into the Recovery HD via the "option" access of the list of boot drives. I can't pull up the old HDD boot data because I erased everything but the user information. I searched online to to find commands for renaming volumes via terminal, but to no avail. Does anybody know some command lines to access and rename disc volumes via terminal? Or is there another way to rename the HDD volume back to the standard "Macintosh HD"? Thanks for your help. Much appreciated! Happy New Year!
