Data recovery is typically thought of in regards to physical damage to a hard drive that renders files impossible to read or retrieve. However, logical hard drive failure – damage to a drive that isn’t physical or mechanical in nature – can cause the same kinds of effects, even though the disk itself is intact. That’s because logical hard drive failure stems from information that is stored on the disk, rather than the disk itself. In other words, bad sectors, data corruption, and disk-write errors make the drive impossible to read. For this reason, logical hard drive problems can often be misdiagnosed and repaired incorrectly.
How DOES This Happen?
Although the symptoms of logical hard drive failure are very similar to the ones associated with physical hard drive damage, the causes are very different. In fact, the source of logical hard drive issues can usually be found in one of the following:
- Computer Viruses and Malware
- Accidental File Deletion
- Formatting or Partial Formatting of the Drive
- System Crashes
- Hardware and Firmware Conflicts
- Power Surges and Brownouts
- Accidental Drive Cloning
- Software and Operating System Corruption

If you’re looking into backup and recovery solutions you’re probably going to hear the phrase “3-2-1 backup” come up a lot. You’ll hear it from most IT consultants and IT pros as well as many backup vendors, who will speak about their products in terms of 3-2-1 compliance.
The 3-2-1 rule is a best practice for backup and recovery. It means that when you build out your backup and recovery strategy you should:
1. Keep at least three copies of your data
That includes the original copy and at least two backups.
2. Keep the backed-up data on two different storage types
The chances of having two failures of the same storage type are much better than for two completely different types of storage. Therefore, if you have data stored on an internal hard drive, make sure you have a secondary storage type, such as external or removable storage, or the cloud.
3. Keep at least one copy of the data offsite
Even if you have two copies on two separate storage types but both are stored onsite, a local disaster could wipe out both of them. Keep a third copy in an offsite location, like the cloud.
The 3-2-1 backup rule is a best practice because it ensures that you’ll have a copy of your data no matter what happens. Multiple copies prevent you from losing the only copy of your data. Multiple locations ensure that there is no single point of failure and that your data is safe from disasters such as fires and floods.
Generally, a virus can be removed without affecting other files, but sometimes deleting a complete archive is a necessary precaution.
