Chances of Recovery

The chances of recovering your entire .pst file depend on the level of disk fragmentation before corruption. Fragmentation is a common phenomenon, because data is never stored in contiguous fashion on the drive. However, if you have used file defragment tools just or some time before data loss, then chances of recovery is greater.

How are .pst files lost?

Most occurring and common instances of losing .pst files are:

• Accidental Deletion
• Formatting or Reformatting
• Unexpected system shutdown or Software failure
• Virus Attacks
• Disk Corruption
• Partition corruption or re-partitioning

Maintain a regular Backup
