To remove a hard drive from a tower computer, users need to back up their data, open the computer case, locate the hard drive, disconnect it by removing the IDE ribbon cable and the power computer and take the drive out. Users should make sure the computer is turned off, while performing the removal.
Whether it is for data retrieval or for an upgrade, taking the hard drive out of a tower computer is something that any average user can do. All it takes is a screwdriver to open the tower case. Some tower computers have nonremovable hard drive units, in which case one should take the entire tower to a repair shop for data transfers.
