Hardware Reasons :

In case, if your hardware get fails in storing or transferring Outlook PST files data, then your PST files may get corrupted. There are mainly three types:

Data Storage Device Failure

Dead device →Under this circumstances, your device will not detected because of reasons like hard drive fails to spin-up when power is applied. This usually occurs because of damaged PCB (printed circuit board) that caused mainly due to power fluctuations, power failures, lightning, surges or spikes as a result of a faulty power source or because of water spilling over device.

Noisy hard drive → Clicking (clacking, knocking) or scratching noises are normally as a result of broken or damaged read/write heads (commonly referred to as a head crash), platter damage or firmware corruption.


Drive not spinning → Creation of beeping or buzzing noises by the device while applying the power. It mainly caused because of spindling motor seizure.

Drive spinning but not detected → This usually occurs because of firmware corruption, faulty PCB or damaged read/write heads.

Drive spinning up and down repeatedly → Repeatedly spinning up and down of the drive. It also caused because of faulty read/write heads, firmware failure or a faulty PCB.

Excessive number of bad sectors → Inaccessible of the drive or struggling for read or write data can be caused. It can be indication of Cyclic Redundancy Checking while writing or reading data and drive will repeatedly runs a scan at start-up.


Drive contamination

Hard drives actually are quite sensitive if talking about contamination. And this is one of the most found reason for corruption of any PST or other files stored on hard drive. Also, sometimes dust contamination can result data corruption or damage.
