Hard Drives degaussed but data still there?

Specs: Windows 7
Company I worked for had some computers degaussed however several months later we found out we had a data leak which was traced back to one of these computers. We called in another company http://datakillers.com and they told us that the computers hadn't been degaussed properly. I really know nothing about this process. Was this something that can easily be done accidentally? Or is this something that was possibly done on purpose?

Degaussed?

Have you tried writing 0s to the hard drives?

I am a hardware guy not a software guy but i try to help.

Probably not. You would need to examine it. There have been comments over the years on how magnetic fields affect hard drive platters.

Back in the old days of lesser Arial density, it was determined that the type of magnetic fields a hard drive might be exposed to probably wouldn't erase the data.

However, modern drives have much higher Arial density, which equates to a smaller change in the platter for each data bit. So it is more likely to be affected by a magnetic field.

Hope that helps.

You can't actually degauss hard drives, the degauss refers to the old CRT monitors.

If you had deleted the parttions then that would have resolved the issue.

eddiesawdust:

It is possible to degauss a hard drive. The process of degaussing is removing a magnetic field from an object. A hard drive, being magnetic, can certainly be degaussed.

You can degause hard drives and it has been done for decades. It is uncommon to do in modern drives only because of the time it takes to remove the drive.

Deleted partitions do not remove data.

Get a software that is designed to do many writes to the entire drive to wipe it. Norton used to or may still offer such a program. Dban is a common free one.

For your information Eddiesawdust, degaussing was invented during WWII where it was used to degauss whole ships to protect them from magnetic mines.

Still used today. Some ports have underwater cables still for that use.
