Changing Partition Scheme Might Cause Data Loss in Mac

Hard drive partitioning is a common need of the majority of computer users. In Mac OS X, the hard drive partitions are known as volume. In some cases, for effective management of stored data, you might need to repartition a Mac hard drive. But sometimes, repartitioning the hard drive may create several critical issues. Such situations generally occurs when the current partition configuration of your hard drive doesn’t enable you to carry out required operation. In such conditions, all of your hard drive volumes become inaccessible and stored data might get lost. At this point, Mac File Recovery is required to retrieve lost, missing or inaccessible Mac hard drive volumes and stored data.

In a practical instance, when you try to install some firmware updates on you Intel-based Mac computer, which is using non-standard partition scheme such as fdisk scheme, the update process might get terminated with the below given error message:

“Unexpected error occurred (0); unable to upgrade firmware.”

In order to update firmware in such cases, you are required to alter the partitioning scheme, which requires the repartitioning of hard drive. This behavior of Mac OS X renders your valuable data inaccessible and put you in need of File Recovery Mac.

How to resolve firmware update issue in Mac OS X

There are two following possible ways to overcome this problem:

  • Use external startup drive: Use external bootable disk, such as firmware disk that is configured with the Globally Unique Identifier (GUID) partition scheme, to start Mac system through Startup Disk preferences. Install updates when the system starts up.

  • Erase and repartition hard drive and reinstall Mac OS X: Format you entire Mac OS X hard drive and delete existing volumes. Then repartition the hard drive using the GUID partition scheme and then reinstall Mac OS X on it.

Among above two methods, the first one might not work in some cases but the second one will work in all circumstances. The second method has a disadvantage that it would remove all of the data from hard drive and cause total data loss. This situation require Mac Data Recovery to be sorted out.

Recovery is potential through advanced Mac File Recovery applications. These tools use cutting-edge algorithms to thoroughly scan affected Mac OS X hard drive and retrieve all of the lost volumes and stored data. These programs allow you to carry out Do It Yourself recovery.

Stellar Phoenix Macintosh Data Recovery is the best ever made and robust tool to salvage lost data in most of the cases. It retrieves data from HFS, HFS+, HFSX, HFS Wrapper and FAT file system volumes. This efficient tool is designed for Mac OS X 10.5, 10.4 and 10.3.9.
