Data recovery. Hard drive testing. Hard drive replacements and upgrades.
Your hardrive is the only moving part in your laptop or desktop so even the lightest of impacts can have drastic consequences. This is not always the end though often data is retrievable and can be saved.
Being a moving component it will have a finite life span so we recommend regular testing to prevent the loss of those important documents or those precious picture memories.
PREVENTION IS BETTER THAN CURE
