JEITA: Deleting data from hard disks won't erase it

A organization backed by Japan's largest electronics companies has issued a warning to PC users that data stored on the hard disk of a computer that is being scrapped or thrown away can be read by a malicious third party, even if the disk has been reformatted, and has called on PC makers to offer software and services to protect users.

"What users normally do as data deletion, is not exactly deleting data," said Atsuko Agata, a spokeswoman for the Japan Electronics and Information Technology Industries Association (JEITA). "It just temporarily puts a mark on data that says this data is unnecessary."

In order to completely erase data from a hard disk, special software is needed and PC makers should offer such software or a related service to their customers, JEITA said in a statement. PC makers should provide information on how to erase data from a hard disk on their Web sites and in their products' manuals, it added.

This is the first time that JEITA has issued guidelines for how PC makers and users should handle the issue of deleting data from a hard disk when disposing of a PC and comes in response to two recent trends, Agata said.

JEITA is aware of many incidents involving sensitive data that has been leaked after the PC this data was stored on was either scrapped or given away, Agata said. In addition, the Japanese government is promoting a measure that would make recycling of consumer PCs mandatory by law, she said. A bill that makes recycling of corporate PCs mandatory has already been passed into law.

JEITA will release detailed guidelines for how PC makers and PC users should handle the issue of deleting data from a hard disk when disposing of a PC in mid-May, Agata said.

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
