On Mac system, hard drive may be logically partitioned into multiple units generally known as Mac volume. A volume in Mac system is the term for whether full hard disk or possibly a section of hard disk drive, which is partitioned into separate logical unit. If the partition is a single drive, every partition is known as a volume. For Macintosh OS, hard drive could be formatted with HFS+ and HFSX file systems. However, data loss on Mac may occur as a result of various situations like accidental deletion of the partition or a volume, corruption of hard disk drive, and accidental reinstallation of the operating system etc. Nevertheless, absolutely nothing to worry nowadays there are lots of Mac partition recovery software available in market, which will help you to recover lost or deleted partition. So as a way to recover lost data you need to choose good Mac partition recovery software.
The 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 would be the most frequent factors behind data loss. Let us briefly reveal few important case scenarios through which data loss on Mac may be occurred.
- Volume header corruption: Volume header is usually located in second sector of the Mac volume where as initial two sectors of the Mac volume that’s sector 0 and 1 are HSF boot blocks. Lot of details about the volume is stored in the Volume Header. Volume Header information includes size of allocation blocks, a timestamp that indicates if the volume was developed, location of other volume structures such as the Catalog File or Extent Overflow File. However, corruption of volume header can result in causing of an error during the time of processing your data from Mac volume. When this happens, Macintosh operating system cannot recognize the volume and leading to data within the particular volume become inaccessible.
- Master Boot Record (MBR) failure: A Master Boot Record is the initial sector of a partitioned Mac hard drive. Its content has details about how the Mac hard disk is partitioned. Master Boot Record holds a partition table, which describes all the information about partitions of a hard drive and it is also called as a partition sector. Anyhow, the Master Boot Record failure could be occurred due to improper shutdown of Mac system caused by power failure. When MBR fails, it is going to lead to data stored on the hard disk drive become inaccessible.
Anyway, Mac Data Recovery software will let you to recover lost data from the Mac hard disk which can be lost on account of previously explained scenarios. This software provides you a complete recovery of lost, deleted, corrupted, or formatted partition on Mac systems. Even you can download trial version of the tool, which will help in previewing the recovered data. Upon satisfying utilizing the demo version, you can go for buying the software complete version.
