Mac OS X has drawn the attention of a range of users worldwide and this the reason why people are now switching from Windows to Macintosh. It is definitely a clear leader on the safety front and has a unique architecture that makes any type of network invasion practically impossible on Mac. Its simple yet intuitive graphics make it the first choice of photographers and designers.
The beautifully designed applications not only make its users more productive, but enable them to have fun while working in such an environment. It works with almost all digital cameras and other peripherals without the need of drivers. Therefore, unlike other operating systems, Mac OS X is less prone to corruption or errors.
Due to abnormal system shutdown, accidental deletion of data, or virus infection; you may bump into the situation of data loss. ‘Disk Utility’, an inbuilt utility in Mac, helps you resolve most of the disk corruption issues. If the Disk Utility fails to repair the error, then you need to go for Mac photo recovery to retrieve all your lost invaluable photos, videos, and other multimedia files.
Consider a practical scenario. Suppose you try to take out photos from your digital camera by attaching its memory card to your Mac OS X computer and encounter the following error message:
When you try to fix the issue by running ‘Disk Utility’, you got a series of messages as follows:
Checking Journaled HFS Plus volume.
Invalid node structure
Invalid B-tree node size
Invalid node structure
Invalid B-tree node size
Volume check failed.
Error: File system verifies or repair failed.”
Causes
Causes responsible for the error are:
- Damaged data structure, library files, or hard disk profiles.
- Node structure corruption.
- File system corruption.
- Some damaged system files.
Resolution
After knowing about the causes of the error, let us discuss the possible resolutions to get over this problem:
- When you get ‘disk unreadable error’ in Mac, you cannot use the disk until it is initialized. Therefore, you have to use ‘Erase and Initialize’ feature of Mac OS X. But, this would lead to complete erasure of the data present on the disk.
If you have an updated backup, you can use this backup to easily restore all your erased data. However, if the backup is unavailable, you should take help of competent photo recovery software for Mac. There are various third-party mac photo recovery tools available on-line that can efficiently recover all deleted or lost images from Mac-supported media.
