Losing a document on your computer is one of those panic-inducing moments. You try accessing your file, but nothing happens, and you are at a loss about how to retrieve your file. Most of these incidents are software issues that you can easily fix. For example, you may have accidentally sent the file to the recycle bin or saved the document in an incorrect folder under an incorrect name. The search itself can be a pain, but the task is nowhere near as painful as data loss because of a hard drive failure, which often requires a professional data recovery service. However, you can take the following DIY steps to try recovering the data yourself.
Data Recovery Software

You'll want to decide if the drive failed because of physical or logical issues. First, see if the drive is making any strange noises or if you spot noticeable degradation signs. Problems opening other files is usually an indication that something is physically interfering with the drive. Physical interferences require a professional data recovery specialist if you're not familiar with handling hardware.
A logical failure occurs when data has been altered, preventing you from having normal access to your files. Often, you can resolve this type of failure with DIY data recovery software. You may want to clone or back up the drive and work from that drive if you're worried about any further damage from system overwrites. Plenty of free programs exist, but some paid data recovery programs are more ideal for recovering all types of data. Simply follow the instructions for the program you choose.
Physical issues aren't as easy to fix unless you're familiar with different hardware aspects. If you've attempted to recover data using the above software method and you continue to encounter obstacles, the problem may be contained in any number of physical components.
For example, a head crash, when the head assembly no longer flies over the circular platters, can make the head assembly spin. Other issues could be in the PCB (the attached circuit board) or the firmware, which is data stored on the drive platters.

If your drive isn't spinning at all because of a short, removing the shorted diode can fix the problem. You'll know there's been a short if the diodes release a burning odor. If not, the PCB, the green circuit board, may need replacing. You'll need to remove the ROM chip and replace the PCB with a matching one.
When the drive is spinning but not functioning, this serious failure indicates a head assembly crash. Unless you're proficient in repairing hardware, this is a job you'll have to leave up to specialists, especially if you have stored data and files that are extremely important.
A good rule to follow is to attempt software recovery yourself as the first line of defense, but don't continue running the drive for more than necessary. Further strain on the drive can cause even more damage. If all else fails, a professional should step in for assistance.
