I used this common in terminal (diskutil partitionDisk disk2 GPT HFS+ newdisk R) from another post here to try to get my 1TB Toshiba External USB HD to work on both PC and Mac. I was trying to do this WITHOUT erasing any files on the drive. Not only did it repartition, it erased everything and is now in a GUID format instead of NTSB. I have some very important things on that drive, from music to legal documents to the only photos in existence of a dear friend who has passed away. I am reading recovery of files is possible so long as nothing it written on the drive. How do I fix this? How do I recover my files? Honestly, unless someone can tell me what to put in Terminal, I have no idea what to do and I cannot afford $100 for software that may or may not do it either. There are several programs out there that say they can recover files but I don't understand how to work them. I am very upset and have been crying for hours. I don't need told how noobish I am or how stupid of a move using terminal like that was. I just need someone to help me. Do I have to repartition it again back to NTSB or can the files be recovered in its now GUID state? Please...someone...anyone..?
