PST file corruption due to hardware reasons

  • Bad Sectors on Hard Drive: This is a frequent issue that occurs when the hard drive of a local machine develops bad sectors. PST files stored on such a drive are prone to corruption, making it difficult or impossible to access them.
  • Network Issues: Today, it's common to store crucial data on a network server. However, what happens when the network server or the devices linked to it experience problems? In such cases, the user may lose access to the stored PST file. Events like network failures or breakdowns can potentially damage the PST file.
  • Sudden Power Failure: An abrupt power outage has the potential to result in PST file corruption. When a PST file is open during an unexpected power failure, it becomes vulnerable to corruption.
  • PST file corruption due to software reasons

  • Malicious Software: The presence of any malicious software on your computer, whether installed or downloaded, can result in the corruption of PST file data.
