Contrary to popular belief, if a computer doesn’t boot because of hard disk corruption all data isn’t lost and the hard disk might even be repairable. There are 2 kinds of hard disk damage. One is fixable by you and the other needs a skilled data recovery facility.
Data retrieval can only be carried out by professionals and can cost up to $1,500 (occasionally higher). Physical damage usually is composed of lousy actuator arms, damaged platters or fried control cards.
NPD happens when the operating system’s file system (fat or ntfs) gets corrupted because of an improper shutdown (for instance ). Although this harm is may seem very bad (if it is preventing you from booting your PC), it is easily fixable with some software that is already including in almost any Windows PC and a USB external hard disk enclosure.
