Unable to transfer files from external hard drive
Even reading with NTFS can be an issue with the OS X system. Assuming you don't have any individual files that are greater than or equal to 4GB, I would switch to a more OS X - compatible format like FAT32. This is both readable and writeable to/from OS X and Windows systems. I would reformat the drive to be FAT32, retransfer your data, and then try the transfer onto the OS X system.
