Hey people, pardon my lack of knowledge in this area, but it would be really appreciated if someone could help me. So here it is: I have a 320GB External Hard Drive under the Master Boot Record Scheme partitioned into 2 (300GB, 15GB). The main partition (300GB) is formatted to NTFS for windows use, and the smaller partition is formatted to Mac OS Extended (Case-Sensitive, Journaled). My system drive is a 1 partition (150GB) drive formatted to Mac OS Extended (Journaled). So in summary, these are the following drives in question: System Drive: 150GB, Mac OS Extended (Journaled) External Drive Partition 1: 300GB, NTFS External Drive Partition 2: 15GB, Mac OS Extended (Case-Sensitiv, Journaled) I installed The Sims 3 in Partition 2 of my External Drive up to Sims 3 - Fast Lane Stuff expansion pack. But then I ran out of space for the next expansion pack. Firstly, I thought of using Disk Utility to repartition the Partition since the main one still had quite a bit of space left. But being under the MBR map scheme, I was unable to do that. I also tried doing it under Paragon Partition Manager and Easeus Partition Manager which ended up locking my main partition and now is only accessible from my Mac via Tuxera NTFS that I installed. Next I thought of copying files from the second partition onto my system drive since there's also available space there. But when I try to copy the files over, I get an error saying: "You cant copy The Sims 3 because it has the same name as another item on the destination volume, and that volume doesnt distinguish between upper- and lowercase letters in filenames." Now I'm stuck with a full partition I'm unable to empty, a half-full partition which is locked in Windows and a System drive I am unable to copy to. I do not have any other hard drives available at the moment so I am unable to back up the 150GB in the main partition of my external drive as well. Seems to me that all my files are at stake. So does anyone have a solution or have encountered this problem before and can enlighten me?
