Even though, Mac OS provides stability of the UNIX Operating environment and adds popular features of the traditional Macintosh user interface, there are possibilities of data loss. Probably the worst thing among data loss is hard drive corruption. Mac supports two different types of file systems i.e. HFS+ and HFSX. It provides advanced File System journaling feature to help in protecting the volume structure integrity. The HFS+ format allows the use of a journal option to reduce the risk of file system corruption. Journaling file systems keep a log of changes in a journal file before committing them to the actual file system. The journal records what file operations like creation, deletion, modification etc. are in progress at any given time. If your system crashes or loses power, the journal can be restarted to make sure operations in progress are completed rather than being left in a half completed or an inconsistent state. This avoids both the possibility of volume corruption and the need of running a lengthy file system check and repair process on the volume after a crash.
Even though, journaling feature protect your file system from unexpected corruptions, human errors like accidental deletion or formatting the journaled Mac hard drive partition cannot be avoided. Here are some possible reasons for data loss.
- Accidental deletion: You might have accidentally deleted a bunch of files from journaled volume and without even checking the Trash, you just emptied it using “Empty Trash” option to free up the hard drive storage space to store new files. After emptying Trash, when you open volume and search some of your important files, they are not present. Have you deleted some of your important files along with group of unwanted files? The answer might be yes!!! After deleting the wrong files, you have done another mistake i.e. emptied the Trash!!! When you empty the Trash, all files and folders are removed from the Trash. Therefore, you cannot restore accidentally deleted files from Trash also.
- Accidental formatting of journaled Volume: Another common error is accidental formatting the volume that had important files instead of formatting unwanted volume. When you format the volume, all your files and folders from that journaled volume gets deleted resulting in data loss.
- Journal corruption: Sometimes, journal file may also get corrupted making all your data inaccessible. When journal gets corrupted, your system becomes inevitably slow and it takes a lot of time to startup. After some time, your journaled volume may crashes resulting in data loss.
The moment you lose data, the first thing you should remember is to avoid panicking. Avoid uselessly clicking several keys to recover the lost data as this will only make things worse. Accidental deletion or loss of data does not make your data on your journaled Mac volume really erased. All your data are still there, it only deletes the information about your files from the file allocation table. They are just invisible or inaccessible. This means that the deleted or lost files from the Mac partition can still be recovered easily with the help of this software. Hard drive recovery Mac software allows user to recover files from formatted hard drive on Mac in couple of mouse clicks.
However, just note down that once you save new files in the formatted or corrupted Mac partition, those new files will be written over the files you want to recover. Thus, resulting in permanent data loss. Therefore, avoid usage of Mac hard drive partitions after data loss and make use of Mac Hard Drive Recovery Software. It can easily retrieve files from Mac Lion, Leopard and Snow Leopard volumes like HFS, HFS+ and HFSX. This software has the ability to recover files by searching them on the basis of their unique signature. Since it has the ability to perform signature search, it can restore any type of files including images, audios, videos, documents, presentation etc. There are chances of hard drive crash due to improper turn off of the computer, frequent reboots and so on. In such situations, you can use this software for recovering files from crashed hard drive on Mac systems. Sometimes the hard drive on Mac operating system may fail to boot which leads to severe data loss issue. This may happen due to frequent read/write operations or operating system crash. In such scenarios, Mac hard drive recovery software will help you to restore data from failed hard drive on Macintosh operating system.
Mac Hard Drive Recovery software has designed with powerful scanning engines that thoroughly scan your corrupted Mac partitions to restore lost data. If you are using iMac computer and the iMac drive gets corrupted due to bad sectors, virus attacks, power failure, file system corruption etc. then don’t worry!!! It can undelete data from iMac hard drive after corruption and also support data recovery from all other popular models of Mac computers like MacBook, Mac Mini, and MacBook Pro etc. This software also provides preview feature to view recovered files before restoring the data to your hard drive. For instance, if you have accidentally deleted or lost some important images files or any other type of files from your MacBook Air hard drive then you can first use the free demo version of this software to restore MacBook Air hard drive files on Mac. By using the free demo version of this software, you can evaluate the data recovery results by previewing the recovered files. If you are satisfied with the results then you can use the full version of the software to save the recovered data.
Simple Steps to recover data from journaled Mac hard drive partition
Step 1: Download and install the Mac Hard Drive Recovery Software and launch it using shortcut menu on the desktop to restore data on Mac. After launching the software, select “Recover Drives/Volumes” option from the main screen and then select either “Formatted/Reformatted Recovery” option or “Volume Recovery” option from the next screen to recover lost data from journaled Mac volume.
Step 2: After that, select the journaled Mac hard drive partition and then click on “Next” option to proceed.
Step 3: After clicking on “Next” option, the software starts scanning process to retrieve lost data from journaled Mac volume. Once the scanning and recovery process gets completed successfully, you can view the recovered files using “Preview” option.
