Mac hard drive can be partitioned into multiple logical units called as volumes (Mac volume). A volume in Mac system refers to either a full disk or a section of a disk that is partitioned into separate logical units. If the partition is a single drive then each partition is considered as a volume. Mac hard drive can be formatted with HFS+ and HFSX file systems for Macintosh operating systems. Loss of data on the Mac hard drive may occur due to various situations. But nothing to worry nowadays there are plenty of third party Mac data recovery software are available which helps you to recover lost or deleted data from the Mac hard drive. So in order to recover Mac data which is deleted or lost on the Mac hard drive you need to make use of good Mac data recovery software.
Loss of Mac data on the Mac hard drive may be occurred due to various situations such as corruption of catalog record, corruption of volume header, failure of Master Boot Record (MBR), journal corruption, corruption of Apple partition map, Failure of disk verify and repair tool, accidental formatting or reformatting the volume, and deletion of partitions after repartitioning the Mac hard drive etc. Let us briefly reveal few important case scenarios in which loss of Mac data on the Mac hard drive can be occurred.
- Volume header corruption: Volume header is always located in second sector of the Mac volume where as initial two sectors of the Mac volume that is sector 0 and 1 are HSF boot blocks. A wide variety of information about the volume is stored under the Volume Header. Volume Header information includes size of allocation blocks, a timestamp that indicates when the volume was created, location of other volume structures such as the Catalog File or Extent Overflow File. Corruption of Volume header may lead to cause an error at the time of processing the data from Mac volume. When this will occurs then Macintosh operating system can not recognize the volume and leading to become data on the Mac volume inaccessible.
- Master Boot Record (MBR) failure: A Master Boot Record is the initial sector of a partitioned Mac hard drive. It contains information about how the Mac hard drive is partitioned. Master Boot Record holds a partition table which describes all the information about partitions of a Mac hard drive and it is also called as a partition sector. The Master Boot Record failure can be occurred due to improper shutdown of the Mac system caused by power failure. When MBR fails then it will lead to become volume inaccessible.
The deleted or lost data can be completely recovered from the Mac hard drive by using good Mac data recovery software. Remo Recover (Mac) – Pro Edition software is able to recover Mac data from the Mac hard drive which is deleted or lost due to above mentioned scenarios. This software supports the recovery of lost or deleted Mac data from the HFS+ and HFSX file system formatted Mac volumes. You can also recover deleted or lost Mac data from the SATA, SCSI or IDE interfaced Mac hard drive.
