Myth: I need a clean room to recover data from a hard drive.

The clean room data recovery myth revolves around “clean rooms” and “Level-3” repairs. It’s based on the false belief that you need an expensive “Level-3” repair in a dust-free clean room environment to safely and successfully recover data from all bad hard drives.

We have an ISO Class 5 clean room, but it’s not required for most data recoveries we perform and we do not charge extra when we need to use it.

The truth is clean rooms are only necessary when the hard drive’s cover needs to be removed and the platters inside are exposed to dust particles (see photo).

This makes sense: if a dust particle or speck of dirt lands on the platter when the hard drive is powered on, the head (which reads the data off the platter) may “crash” into the obstruction. This can lead to scratched/damaged platters and broken heads.

But it’s important to note, only an experienced data recovery technician (not a computer technician, Apple “Genius,” or even your company’s top IT guy) can accurately diagnose a hard drive to determine that a Level-3 repair is necessary. Even the most computer-savvy user would suspect a “clicking” hard drive has bad heads — it’s often not the case. Only by using our specialized data recovery tools, along with years of research and real-life experience, is an accurate diagnosis possible.

Even other top data recovery companies fail to accurately diagnose hard drives (intentionally or otherwise)!

While most clean room data recovery companies have the experience and tools to properly diagnose a bad hard drive, a data recovery company’s diagnosis cannot always be trusted. Data recovery companies with high rates will tell you that your hard drive needs level-3 repair (the “most expensive” scenario), regardless of the problem (often even before they properly diagnose the drive).

In our experience, about 70% of all bad hard drives can be successfully recovered without the need for level-3 (“expensive”) repair in a clean room. If the drive wasn’t dropped, this number jumps to about 85%.

The only way to get a truly honest diagnosis is by taking it to a company like ours, where we have flat rates for all data recoveries, the tools and experience required to provide an accurate diagnosis, and a low flat-fee — so we have no incentive to “fake” our diagnosis and get you to pay an outrageous price.
