A laughable decision, which makes it all the scarier. Does this mean you can't defrag your drive?
It wasn't his drive.
This is a civil suit not a criminal one. You have read between the lines here. Citrin obviously started his new competing company before he left his employment, like many employees do. All this case says is that the employer has a cause of action for destruction of data against Citrin. In this case it will be virtually impossible to assess damages for this act because the employer will never be able to establish what this data would have yielded them had it not been destroyed.
Your drive? Sure. Your bosses? Get permission first.
