Partitioning is dividing hard disk drive of the computer into multiple drives. Each partition is often a portion of your hard disk drive and it works like it’s a separate hard drive. Partition is named as Volume in Mac operating system. Partitioning is necessary because keeping data, applications and OS on the same partition can be dangerous. If the partition get corrupted or lost from the system you won’t be able to access that drive. Even if you boot with external drive you won’t manage to access complete data. So as a way to recover deleted Mac partition you have to take advantage of good partition recovery software.
The Mac operating system includes two local partitions i.e. HFS+ (Hierarchical File System) and HFSx (Hierarchical File System Extended). Journal corruption can corrupt Mac partitions because HFS+ and HFSx supports journaling feature. Journal file is as just like log file which ensures you keep memory of file modification done on hard drive. If your computer fails due to fluctuation in voltage then journaling feature helps us to recover missing partitions on Mac. But sometimes, journal file itself gets corrupted because of hardware problems or abrupt system shutdown and marks invalid entries in the file system which leads to corruption of whole file system and makes data inaccessible. Also, Catalog file corruption is the one other scenario which results in data loss. Catalog file is an important system file that’s managed by file manager where we could easily access files. Once this catalog file gets corrupted because of power problems, virus attack, malfunctioning of application it is not easy for that Mac operating system to access files from catalog file which also leads to loss of data.
When the partitions are lost or corrupted because of common reasons like hard drive crash, virus attack and power surge problems, volume header corruption and partitioning errors then data which can be important on your hard disk will likely be lost or data becomes inaccessible. In these situations, generally people re-install their Mac operating system but while re-installing it’s necessary to re-format your existing partition which results in data loss in this particular partition. There is another instance where you can format wrong partition as if you need to format your C drive by mistake you typed drive letter D, then this data in the drive D will likely be lost. Care needs to be taken while typing drive letter to get formatted. Sometimes, there are chances of deletion of data if we are transferring data from hard drives or memory cards to the system.
When your partition/volume is lost then do not format hard disk or re-partition it and don’t try to re-create the partition. Also, don’t save any new files on the drive containing lost partitions because, over writing of data results in permanent loss of data. Mac hard disk drive recovery problem might be solved by using Remo Recover (Mac) – Pro Edition software. It recovers data from hard disks like SATA, SCSI, IDE and memory cards, USB drives and iPods.
This effective recovery software has two built-in definitive volumes scanning engine which retrieves data from accidentally formatted partitions/volumes and helps in partition recovery from Mac. Additionally, it contains in-built deep scanning algorithms which find and recover data from missing or deleted Mac volumes/partitions which performs rigorous scanning to undelete data even from inaccessible and missing volumes. With the aid of this software you may also recover deleted partitions from notebook, iMac, and iBook and Mac book. This application is safe as it is a read only application means it won’t overwrite the information in unaffected volumes on the hard drives. Download demo version of this application evaluate the recovery results.
