Here are some hardware-related issues that you need to keep in mind. 

Unstable Internet Connection

If your computer has an unstable or poor internet connection while you’re processing the syncs, it could cause the PST files to corrupt. This situation takes place when the PST data files of your MS Outlook application are stored on the network drive. The same case is also applicable to the OST files.

The issues associated with corruption will take place if a small part of the data files is stored in the sector that has been turned into something that can aid in Outlook corruption. If you’re facing random PST file corruption as well as disk performance problems, you need to conduct a surface test so that you can determine whether your hard disk contains bad sectors or not. Make sure you follow the proper guide so that you can prevent the bad sectors in the hard disk from affecting your PST and OST files. 

Sudden Power Outrage
