Apple’s Disk Utility comes equipped with Mac OS X which is a tool created to perform disk related operations such as mounting hard drive, verifying disk integrity, disk formatting and partitioning, disabling or enabling journaling and creation of disk images.

Since you are not familiar with the disk utility tool, you have lost your vital data. The wrong usage of this utility might delete your files and reformat the needed sectors.

No matter disk Utility is a useful utility, but in some versions of Mac OS X, it may not function properly. Particularly in Mac OS X 10.5 Leopard, Disk Utility may show unexpected behavior when you try to change, delete or format a hard drive volume.

Repartitioning of the drive rewrites the partition table contents with a new volume scheme in the storage media which eventually leads in loss of the previous partitions. Consistently the most valuable data held by previous partitions is lost. The volumes currently mounted are newly created partitions, and crucial data which were stored on the previous partitions are lost forever.

In such cases, you can Recover Mac volumes and the critical data stored on them using one of the best software called REMO Mac Recovery Software.

This powerful software is equipped with distinct search algorithms for “lost partition finding from reformatted drive” and “data excavation from lost partitions” which can recover data from lost partitions even in case partition table scheme is changed. This non-destructive recovery software works on Mac OS X 10.4 or later on both Power PC and Intel based platforms.

First you can go with the free demo version of REMO Mac Data Recovery Software to evaluate the results. Once you are satisfied with the result, you can go for a full version and recover the data you are eagerly looking for.
