Common causes of hard drive corruption
Corruption happens for a number of reasons.
Age
Corruption is more likely to happen on an older hard drive. This is because the data within it degrades over time to the point where files become unreadable. This kind of degradation can happen during operation or even on a storage device that is rarely used.
Malware/viruses
Despite what you might read in ransomware emails, viruses cannot physically damage your storage device. However, they can damage the data within your storage device enough to make it unreadable.
Interruption during writing
Anything that disrupts the writing process (copying files, saving document changes etc.) can cause data to become incomplete, making it inaccessible or compromised. Common examples of causes include:
Common symptoms of hard drive corruption
It’s unlikely that files will just go missing as a result of corruption. You’ll usually notice other symptoms, which can include:
- Sluggish performance: Files take longer to load, save or copy
- “Blue screen of death” (BSoD): The operating system fails to boot up (this happens when your operating system files are stored on the corrupted device)
- The drive isn’t recognized: Nothing happens when you connect your device to a computer
- The Operating System may prompt to run CHKDSK or other file system repair tools.
