Toshiba made the world's first commercialization of "HDD that invalidates data when connected to unexpected equipment", evolved form of "HDD to forget"

In August 2010"HDD to forget" to instantaneously invalidate data by simply removing the HDD from the deviceToshiba developed 2.5-inch HDD that invalidates data when connected to unexpected equipment.

"HDD to forget" was a mechanism to invalidate data when the power supply was cut off, but in order to use it more conveniently at the actual site of use and to strengthen security, it is connected to devices other than those that have been certified in advance And technology to invalidate data developed. With this, even if the HDD is stolen, since the data is invalidated at the stage of being connected to the unauthorized device at the theft destination, data leakage can be prevented beforehand.

Details of "HDD that invalidates data when connected to unexpected equipment" is from the following.Toshiba: News release (2011-04-13): World's first 2.5-inch HDD to invalidate data when connected to unexpected equipment commercialized

The HDD developed this time will be used to authenticate devices such as digital multifunction devices, HDDs, POS systems, and PCs that have the HDD itself. When the HDD itself determines the on-board device and is connected to an unexpected device, the HDD itself automatically erases the "encryption key" necessary for decrypting the encrypted data recorded on the disk and instantaneously Invalidate by making it unreadable. Also, for device authenticationChallenge response methodIs adopted.


The conditions for invalidating data can be selected from three different modes depending on the application, and furthermore, it is possible to set "invalidation area" and "save in encrypted state without invalidation" in each mode.

The first is "Invalidate data with instructions from onboard equipment" which is also possible with conventional HDD, the second is "function of HDD to forget" developed in August last year "When power supply is cut off Invalidate the data ", and the third is" Invalidate data when connected to unexpected equipment "developed this time.

Appearance of "MK6461 GSYG". The capacity is 640 GB.
