The data from various types and ages of computers, laptops/notebooks, Apple Macs and portable hard drives, and USB sticks can all be theoretically recovered.  The need for data recovery is usually due to a failed hard drive or because a computer will no longer boot up.  There are also other causes of data loss.  Computer repair businesses usually offer data recovery as a service.  There are also specific data recovery laboratories which specialise in recovering data from badly corrupted and or damaged Hard Disk Drives. These laboratories have Class 100 clean rooms where they dismantle the Hard Disk Drive in a dust free environment and then rebuild them to recover the data. This isn’t a simple job done on the kitchen table but a very precise and technical work place environment with very skilled staff. Don’t take a hard Disk Drive to pieces at home because the risk of losing all your data grows exponentially.
