Data Recovery from HFS and HFS+ Partition?

What is HFS and HFS+ Partitions?

Expanding as a Hierarchical File System, HFS is a file system present in Macintosh hard disk drives used in Apple products. HFS file system is specially designed to support the hard disk drive upon formatting in order to create a directory that could further form new folders and files. As HFS file system was uniquely designed` for Mac systems which means it cannot be opened or even recognized in a Windows computer system.

However, HFS could not fulfill the requirement of accommodating hard disk drives storing high volumes of the data such as 100 GB and above, the need for a better file system was felt. Therefore, Apple introduced an advanced file system which was named HFS+ partitions which also known as HFS was extended. HFS+ created files and folders which were smaller and had reduced block sizes which further reduced the space taken by each file and folder. Hence proving that HFS+ was capable of managing the space in a more efficient way especially on larger disks.

More space stored more data and hence whenever there is a data loss issue, the user loses a lot more data than usual. So, there is a need for a better option for Mac data recovery from HFS which also covers the recovery of HFS+ partitions.

What are the reasons for HFS and HFS+ Partition Data Loss?

There are various reasons which result in the data loss from HFS and HFS+ partitions and here is a list of the few very common ones:

  • Accidental Formatting: Users tend to format the partition accidentally which will directly affect the data present on the hard disk drive.
  • System Crash: System crashes are abrupt and hence there is a hundred percent chance of some damage to the data on the system during a crash.
  • Virus Infection: Not a very uncommon reason for any kind of storage media to lose data is virus and malware infection. They damage the files and corrupt the data which needs to be recovered.
  • Directory Corruption: Directory corruption is a type of corruption when the MacOS cannot read them or access the hard disk drive.
  • Incorrect Shut Down: An incorrect turning off of a computer system can also lead to corruption of a file as the OS will not have enough time to store the files in use.
  • Rapid Deletion: When a drive starts running out of space, the user tries to delete the unwanted files which are taking a lot of space. This might lead to the deletion of important system files which can corrupt the file system.
  • Incorrect removal of a hard disk drive: Always ensure that a hard disk drive is removed properly and failure to do so can lead to the corruption of the file system.
  • Incorrect file system format: If there is an error saying “incorrect format,” it means that the system is most probably infected by a virus.
