"How do I recover data after formatting HFS+ disk by accident? Well, there are two partitions on my Mac and the partitions have HFS file system. However, I mistakenly formatted HFS+ partition and lost all data stored on this partition. I want to know if there is any way to perform HFS file system data recovery after formatting. Can anyone give me some help?"
Compared with PC which runs Windows OS, Many people like to use Mac computer. Mac OS is quite different from Windows OS. As you know, NTFS file system and FAT32 file system are common file systems on Windows OS, while HFS or HFS+ file system is commonly used in Mac OS. When you format HFS+ disk partition by mistaken, files will be erased immediately. However, all files are not erased permanently, so you still have chance to recover data after formatting HFS+ disk on Mac.
