Introduction
Having an external hard drive fail can be incredibly frustrating. Often, external hard drives are used to store important files and memories, like family photos, financial documents, creative projects, and more. When the drive stops working and that data becomes inaccessible, it can feel like everything is lost.
However, there are often still options for recovering data, even from a seemingly dead external hard drive. In this article, I will provide an extensive overview of the various data recovery options that may be available if your external hard drive fails.
Diagnosing the Issue
The first step is to properly diagnose why your external hard drive is not working. There are a few main failure types:
-
Logical failure – This is when the drive’s file system gets corrupted. The data is likely still intact on the disk, but the operating system can’t access it anymore.
-
Mechanical failure – This is when there is a physical problem with one of the hard drive components, like the read/write heads or spindle motor. It requires specialized repairs in a clean room environment.
-
Electronic failure – Problems with the hard drive’s circuit board can prevent accessing the data, even if the disk itself still works.
To confirm it’s not just an issue with the enclosure or USB connectivity, I would recommend connecting the bare drive directly to a computer internally or via SATA adapter if possible. This bypasses the external housing and USB interface.
Attempt Data Recovery Yourself
If you are technically inclined, you may want to try recovering the data yourself before bringing it to a professional recovery service. Here are some options for DIY data recovery:
Data Recovery Software
- There are many data recovery programs available such as ReclaiMe, Disk Drill, EaseUS Data Recovery Wizard, Stellar Data Recovery, etc.
- These allow you to scan the drive and extract recoverable files.
- Many have free trial versions so you can see if your files can be recovered before purchasing.
Linux Live CD/USB
- Booting from a Linux live environment allows you to access the external drive without mounting its file system.
- You can use file carving and disk cloning tools like ddrescue to image the drive and extract files.
- Popular distributions like Ubuntu have GUI data recovery tools included as well.
Remove the Drive from the Enclosure
- Connecting the bare hard drive directly to a computer can help if the external enclosure has failed.
- Use a SATA/IDE adapter and access the drive like an internal one.
- This allows you to run data recovery tools directly on the disk.
Use a Professional Data Recovery Service
If you exhaust the DIY options without success, your best bet is to turn to a professional data recovery company. Here is an overview of this process:
Finding a Reputable Service
- Search for ‘data recovery’ near you and vet companies thoroughly from online reviews.
- Look for positive feedback about reliability and recovered data quality.
- Avoid low budget options that could further damage your drive.
Initial Evaluation
- The company will do an initial diagnosis to determine failure type, possibilities for data extraction, and total costs.
Recovery Process
- Professional services have access to specialized tools and clean room facilities to safely repair drives and recover data.
- Advanced techniques like disk imaging, firmware repairs, transplanting drive components across donor drives allows them to rebuild inoperable drives.
Return of Recovered Data
- Once repair and recovery is complete, your data will be transferred to a new external hard drive that you can take home.
- Be sure to ask about backup options like cloud storage or tape drives for redundancy.
Total Costs
- Costs vary greatly based on failure type and recovery methods needed. Expect anywhere from $300 to $3000+ in fees.
- However, keep in mind this data is likely invaluable to you and impossible to replace if not recovered.
Preventing Data Loss in the Future
Going through data recovery is always a hassle, so make sure you’re taking steps to avoid potential data loss down the road:
-
Have a robust backup strategy – Maintain multiple copies of important data, with at least one offline backup and/or cloud backup.
-
Handle drives carefully – External hard drives are susceptible to shock damage and disconnect issues. Avoid undue wear and tear.
-
Monitor drive health – Keep an eye out for warning signs like slow performance and bad sectors.
-
Replace older drives – Hard drives have a limited lifespan. Upgrade to a new drive after 4-5 years.
Conclusion
Recovering lost data from a failed external hard drive is often possible through various DIY methods or professional data recovery services. While the process can be complicated and/or expensive, your data is likely worth the effort and cost. Just be sure to have solid backups so you hopefully never need to resort to recovery options in the first place. Let me know if you have any other questions!
