HFS+ is improved by Apple Inc. on the basis of the earlier HFS file system. It has replaced HFS gradually and become the main file system of Mac operating systems. Compared with HFS, HFS+ has many advantages, so it is widely concerned by many Mac users since its publishing. And Mac users convert HFS to HFS+ for saving and using data better. But what if HFS+ is lost? Is there any way to recover lost data from HFS+ partition? When encountering data loss, different Mac users may use different methods to recover lost data from HFS+ partition. Among those methods, the most economical and practical and safest one is to recover lost data from HFS+ partition with professional Mac data recovery software.

Advantages of HFS+
1. Adopting 32 bit to record number of allocation blocks: In HFS+ partition, there could be 232 allocation blocks at most in one partition. And adopting 16 bit to record number of allocation blocks, HFS only allows 216 allocation blocks at most in one partition. In HFS+ partition and HFS partition which have the same sizes, number of allocation blocks in HFS+ partition is larger than that in HFS partition. Thus, HFS+ partition has smaller allocation blocks and improves space use ratio and increases storable file number.
2. Supporting long file name: HFS+ supports file names with a length of 255 characters and HFS only supports 31 characters. So HFS+ can describe files more accurately.
3. The size of directory tree node increases to 4KB: HFS+ not only has larger directory tree node, but also is able to change storage node size according to size of index node, which reduce wasted space and create a directory structure storing more information for quick index on ever accessed files.
4. Single file size is 263 bit at most: HFS+ supports single file of 263 bit at most and HFS only 231. So HFS+ can satisfy users' demands for large file storage.
5. Faster boot speed: HFS+ identifies a boot fie with location and file size information in partition head. This boot file can be found easily when system boots, thus quickening system boot speed.
Since HFS+ has so many advantages, many users have converted HFS to HFS+ in Mac. Then we'll introduce how to recover lost data from HFS+ partition. Take recovering lost data from damaged partition for example.
