In most cases, they don't want to destroy the data. Anyone wants to retrieve their important data from a failed hard drive or a damaged media.  We've had successful experiences with WeRecoverData in retrieving critical data from damaged hard drives.

Destroying Data

NO RATINGS
Even destroying data on a computer requires work. Deleting all files and then overwriting the disk with random or unimportant data is certainly an approach. As multiple overwrites occur, the data become harder and harder to recover. Destroying the physical disk is another approach.  I was surprised to find that the steel used in my disk drive was so hard that it broke my drill bit before the drill bit reached the disk platter.

With components buried in the SmartPhone which makes them hard to remove and destroy discretely, scrubbing SmartPhones is a much more challenging task.

Funny thing is, all too often when we WANT the data, it can't be retrieved.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
