Macintosh OS gives an environment of unusual simplicity, strength and elegance to the person. Mac Operating Systems support various file system as compared to Windows. HFS+ is the default file system present in Mac Operating-System.

There are various kinds of hard disks available that have huge capacity of storage area. The storage capacity of a personal computer may vary from few Gigabytes (GB) to Terabytes (TB). It is difficult to store and manage all information in particular location so that person can create partitions in their hard disk drives. Partitioning a hard drive create different logical partitions and provide another space for storage. But many instances most of the person experienced issue like losing a partition. These kinds of lost partitions in Mac systems can be retrieved by simply performing partition recovery on Mac using appropriate partition recovery tool.

Windows Operating System is designed by Microsoft Company with very first edition as Window1.0. But Windows became popular right after DOS Operating Systems. Later releases of Windows are more Users pleasant and also productive. Windows 7 is latest release of Microsoft and is also very popular all over the world.

Now, Mac OS X is more compatible with network systems like Windows NT, Windows 2000, AppleShare, SAMBA etc. Mac OS X uses HFS, HFS+ and HFSX file systems. You can format optical disk, thumb drives and hard drives with Mac partitioning structure and file system. In order to support modern Intel processors, older Mac drives and standard PC compatible volumes, Mac supports three different partition schemes like GPT (GUID partition Table), APM (Apple Partition Map) and MBR (Master Boot Record).  GPT scheme is mainly used by modern Intel processors, APM is used by PowerPC based Macs and MBR is used by Windows compatible PCs. Although, Mac is not able to boot from MBR partitioning scheme, Mac can able to access MBR partitioning. Mac file system such as HFS, HFS+ and HFSX retain most of their data in extent and catalog files. Sometimes, these catalog files may get corrupted resulting in data loss. There are many repartitioned Mac hard drive recovery software available to recover lost files from Mac OS X. Based on data loss complexity; you can choose reliable Mac disk recovery software to recover Mac OS X files, which have been lost.

A catalog file behaves like container and holds information of files and folders stored on your volume. These files and folders are recognized by CNID (catalog node ID) in catalog file, which is assigned during file creation time. Catalog file is maintained by file manager and organized as B-tree so that it can allow quick and efficient searching. Catalog file contain map node which stores information regarding the nodes that are in use and the nodes, which are free. Catalog file helps you to find any files or folders from your Mac hard drive. Therefore, if this catalog file gets corrupted due to improper system shutdown, power failures, Operating system crash, and volume header corruption etc then you cannot be able to access files and folders resulting in loss of files.

Generally, when you connect new hard drive to your computer, it is automatically detected and listed in the Disk Utility as a basic disk. After that you need to divide the hard drive storage area into logical storage areas and then format those areas before using to store new files on your Mac hard drive. Disk utility offers the capability to create, format and delete the volumes on basic disks. Dynamic storage disk allows you to create three different types of volumes like Simple volume, Spanned volume and Striped volume. You can able to create 100 volumes per dynamic disk. You can also extend simple volumes using third party disk utilities. When you extend a volume, only more storage area is added to simple volume from free space, which exists on the same hard drive. In Mac Operating system, first volume is named as /dev/sda 1 then the second volume is named as /dev/sda 2 and so on. The files are stored on these volumes are managed by file system. Mac OS supports HFS, HFS+ and HFSX file system. Sometimes, the data may be lost due to Operating system crash, improper system shut-down, power failures etc. In such instance, you can recover Mac data from Mac volumes. There are many Mac disk recovery software applications available; you can use one of the effective recovery tools to recover your lost data.

Generally, when Operating system crash occurs or when your system is not shutdown properly then parameter random access memory (PRAM) of your Mac OS get corrupt resulting in incorrect information about your system, which may in turn results in loss of files. PRAM is addressable area of RAM, which is able to store identity of your Mac OS. This PRAM stores information regarding how much memory exists, security, how your system boots. You doesn’t have unlimited privileges to change this information. PRAM also stores the settings, which you have created when your system is running. Therefore, when this PRAM get corrupted, the information stored on this memory get corrupted, which may not allow you to access the files stored on volumes resulting in loss of files. Sometimes, you may accidentally delete the files using Command + Delete keys resulting in loss of important data.

File system marks that space as available to store new data. The data you have deleted still exists on hard drive until you save or copy new data over volumes from where you have deleted. Therefore, stop using affected volume and use effective Mac disk recovery software to recover missing data.
