Data recovery is the process of recovering lost or deleted data from hard disk (hdd's). A hard drive fails when it can no longer read and write data, which usually happens because some part inside the drive has malfunctioned. Common symptoms include a clicking noise while trying to access the drive, low performance levels and strange error messages when launching programs or booting. If the hard drive is still under warranty, many companies offer to replace it for free. However, if you purchased your computer without a warranty and are unable to get the company's assistance in recovering data from your hard drive, there are several options available that can help you retrieve your important files. These include using software designed specifically for data recovery, sending your hard drive to a professional data recovery service or using a do-it-yourself method. When deciding on a data recovery method, it is important to consider the severity of the damage to your hard drive, as well as the cost and time involved in each option. For instance, if the hard drive is damaged but not physically broken, using data recovery software might be the best option. On the other hand, if the drive has been physically damaged or shows signs of physical failure such as metallic sounds from spinning platters and scratching noises, a professional service(
