Administration and full control of all main functions of the hard disk belong to the PCB board. Writing and reading any information is performed with special magnetic heads that do not touch the platters when working, which improves the hard disk lifetime. The main elements of the hard disk are rigid glass or aluminum platters coated with special stuff and meant to store data. For example, business and personal documents, music, videos, various phots and pictures, electronic messages, projects and presentations, scientific and literary research works, games and so on – these are only a small portion of all data that a hard disk stores and provides access to. Later in this article, we will focus on the main causes of hard disks getting damaged, and explain how to restore the lost data.īefore we get to describe possible causes that make a hard disk damaged or broken down, it’s worth taking a look at how a hard disk is arranged inside to have a better understanding of possible problems.Īn HDD a hard disk (in other words, a hard disk drive) is a mechanical mass-storage device which is meant to write, retrieve and store various user information. Despite of all the grim colors here, this situation is not that critical, and user data can still be saved. Very important user data accumulated over the years with much effort can be lost, and recreating it again (for example, things like personal photo and video archives) does not seem possible at all. It’s no surprise that if a hard disk is damaged, broken or has some operation issues, all the information it contains becomes inaccessible for the user. Regardless of being internal or external, such disks have the largest capacity compared to other data storage devices which is the key to understanding their wide range of use and extreme popularity. The main element of a desktop PC or laptop in charge of safe data storage is a hard disk, also known as HDD. How to Recover Data from a Damaged or Non-Operable Hard Disk.Causes of damage to the hard disk and possible preventive methods.Possible Symptoms of a Damaged Hard Disk.Using a drive after it shows signs of partial failure can lead to complete data loss. Hard drive failure caused by mechanical damage is always considered physical damage and requires the help of data recovery professionals to extract your data. Even non-moving parts, like the sensitive circuit board, can become damaged and fail, leading to complete data loss. Do not continue to use the drive or you risk complete hard disk failure and data loss.Ī hard drive is a complex piece of equipment with multiple moving parts. If you continue experiencing bad sectors but your hard disk drive is still booting, copy all data from the drive and replace it. But when repeated bad sectors are created, it could be a sign of hard disk failure, which could lead to complete data loss. If only one bad sector occurs, this could be an isolated incident. A sector of the drive may become worn down or damaged from too many read/write cycles. Bad sectors can occur on traditional hard disk drives or solid state drives after time. A bad sector is a space on the hard drive platter that won’t read or write data. If you’ve already lost data, which is often the case, contact a professional data recovery service to extract the data.īad sectors can occur from logical or physical damage. If the drive is still use-able and you did not lose any data, back up your files immediately and replace the drive. You can often detect a head crash if a hard disk drive is making grinding or clicking noises. If the head continues scraping the platter, the data may become unrecoverable. When the magnetic disk head continues to contact the rotating platter, this can lead to progressive damage. Let’s look at three different ways a hard drive can fail and the steps you should take when this happens. Whenever you lose data, whether it’s one file or an entire drive, call data recovery professionals to help. It’s important to remember that attempting do-it-yourself data recovery can turn what would be a relatively “easy” logical recovery for a professional service into a data recovery disaster, where it is either impossible or very time-consuming and expensive to recover lost and damaged data. Data loss from logical disk drive failure can usually be fixed by a professional data recovery service. The damage might be complete, with no hope for recovery, or the drive may be easily recoverable. Physical failure means damage to the hard disk drive itself.ĭrives may fail to varying extents. Logical failure typically involves corruption of files or accidentally deleted data. On the pages of this blog, we frequently talk about physical and logical hard drive failure. At 24 Hour Data, we know this better than anyone.
