In Mac OS X File system corruption are common problems in every computer operating system. These cases might occur due to improper system shutdown, virus infection, incomplete operating system upgrade and many alike. In order to overcome such situations, Mac OS X offers a powerful inbuilt utility, known as Disk Utility. You can run Disk Utility directly on any Mac OS X hard drive, it will detect and repair most of the errors.
But in case of severe file system and disk corruption scenarios, this tool can not detect and fix the hard drive errors and the hard drive remains inaccessible. Such circumstance cause critical data loss situations, Mac Data Recovery is required to retrieve lost data. In a practical scenario, when you try to repair a damaged Mac OS X hard drive volume using Disk Utility, you might come across the below given error message:
Checking Catalog file.
Invalid key length
The volume hard drive name needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair”
Once these error messages popup, Disk Utility stops scanning the hard drive and thus it could not detect the hard drive errors. In such scenario, the problem remains intact and you come across Mac data loss scenarios. At this point, you are required to find out the cause of data loss and go for Mac Recovery solutions to by sorting it out.
Try following things to sort out the above issue:
Run Disk Utility from Externally mounted FireWire drive.
Attempt the single user restart Cmd-S and run fsck -y.
Try to run the Disk Warrior from another hard drive volume.
When all else fails, you need to rebuild the hard drive by formatting it and reinstalling the operating system. It is the last resort to sort out all types of hard drive problems. But it also has a disadvantage that it removes all of the hard drive data and cause serious data loss situations. In these cases, you need to carry out Data Recovery Mac using third party applications.
These tools use high-end scanning techniques to thoroughly scan the affected hard drive and retrieve all of the data from it. Mac Data Recovery software are quite easy and safe to use.It recover mac data and supports snow leopard version of apple.
