  • Data loss due to re-formatting a partition: Sometimes you may feel its necessary to change from one file system to other file system on Mac or HFS+ to HFSX file system on Mac. Errors during the file systems conversion can result in corruption of the partition.
  • Data loss due to re-partitioning the hard drive: When the size of an existing partition needs to be changed or a new partition needs to be created, re- partitioning can be done. Improper re-partitioning process might corrupt the existing partitions and results in loss of data.
