The operating system crashes is inconvenient, but everything can be catastrophic if the hard drive fails. This means that the bits are destroyed along with the data on them (unless you have a backup). But is your hard drive really failing or just so close ? This wikiHow teaches you how to mitigate some of the damage, but be aware of the risk and you should only try it if the data on the drive isn’t important enough to pay for repair. professional. In case these data are extremely important to you (for business or legal purposes), THIS METHOD SHOULD NOT APPLY. If you’re planning to throw away or recycle a completely failed hard drive, continue with the steps below (remember, nothing is certain).
Steps
Determine hard drive health

Check for damage. Check to make sure the drive is completely damaged by looking at possible causes of the hard drive not being recognized by the computer.
- If the drive rattles loudly and steadily, stop and move on to part two. This means that the hard drive has completely failed.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e9/Fix-a-Physically-Broken-Hard-Drive-Step-2-Version-2.jpg/v4-460px- Fix-a-Physically-Broken-Hard-Drive-Step-2-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e9/Fix-a- Physically-Broken-Hard-Drive-Step-2-Version-2.jpg/v4-728px-Fix-a-Physically-Broken-Hard-Drive-Step-2-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Check hardware connection. These locations are the best places to start looking, if the problem is here then fixing it will be very quick and inexpensive!
- Check to make sure the computer is still connected to the power source. If the plug or cable is accidentally dropped or damaged by a naughty cat, the system will stop working.
- Open the computer case. Are the power and data cables (IDE or SATA) firmly plugged in and in place? These cables must stay in place, with no pins bent, broken or damaged.

Observe the whole thing at once. Sometimes the drive is not the problem but the printed circuit board that controls the operation PCB located underneath. If the problem is caused by the power supply or the component failure on the printed circuit board, the drive will definitely stop working because it is not operated.
- Watch for signs of damage such as wear or burns. If you see these marks, rest assured that you can fix them relatively easily.
- If you want to replace the PCB board, you can Google the parts for the drive model and manufacturer.
- Before proceeding, you need to remove the old circuit board (which is secured with 5 screws, be sure to hold them carefully!).
- Slide out the old drive and replace the board with a new one. Avoid touching the metal conductors on the new board as static electricity can damage things before you can use it. You can ground yourself by wearing an antistatic bracelet, touching metal or something on the ground (or the inside of your computer while it’s plugged in).
- Insert the new board into the drive firmly, then screw in place.
- Reconnect the drive to the computer and then turn on the power. If the drive works, you have succeeded. You can proceed with data backup at this time.
- If that doesn’t work, continue.

Check if the drive is recognized. If everything is in place and still nothing shows up in the controller PCB, go to Windows Disk Management, BIOS, or Mac OS X Disk Utility to see if the drive is recognized.
Repair options

Choice: if this data is important, you will need to find a professional hard drive recovery company and pay them to recover the data. If you do the repair yourself, the odds of being able to recover the data professionally are almost nil.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/70/Fix-a-Physically-Broken-Hard-Drive-Step-6-Version-2.jpg/v4-460px- Fix-a-Physically-Broken-Hard-Drive-Step-6-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/70/Fix-a- Physically-Broken-Hard-Drive-Step-6-Version-2.jpg/v4-728px-Fix-a-Physically-Broken-Hard-Drive-Step-6-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Do a quick Google search for “hard drive replacements” to see a few different directions. Parts replacement may work for older equipment, but modern hard drives don’t.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/12/Fix-a-Physically-Broken-Hard-Drive-Step-7-Version-2.jpg/v4-460px- Fix-a-Physically-Broken-Hard-Drive-Step-7-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/12/Fix-a- Physically-Broken-Hard-Drive-Step-7-Version-2.jpg/v4-728px-Fix-a-Physically-Broken-Hard-Drive-Step-7-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Self-repair. The method that brave and technically minded souls love is DIY. This method is promoted by companies that specialize in providing discrete components with the idea that if you just replace the burned out control board, the hard drive will work again.
- Actually this possibility is there. However, the biggest risk is this: the chips on the control boards are increasingly being calibrated specifically for the specific drive, so there’s no guarantee that the replacement will work. Either way, this is the least expensive option.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/1a/Fix-a-Physically-Broken-Hard-Drive-Step-8-Version-2.jpg/v4-460px- Fix-a-Physically-Broken-Hard-Drive-Step-8-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/1a/Fix-a- Physically-Broken-Hard-Drive-Step-8-Version-2.jpg/v4-728px-Fix-a-Physically-Broken-Hard-Drive-Step-8-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Get professional help. This is the ONLY option to get the drive working again, or at least recover the data on it (your ultimate goal).
- This solution is sometimes faster than doing the repair yourself, and the success rate is also higher, but you will have to pay a fee. As long as these data are important, these costs may be worth it.
- You may even end up paying two to three times the original hard drive price, so weigh the cost against the value of the data on the drive.
Self-healing
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a8/Fix-a-Physically-Broken-Hard-Drive-Step-9-Version-2.jpg/v4-460px- Fix-a-Physically-Broken-Hard-Drive-Step-9-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a8/Fix-a- Physically-Broken-Hard-Drive-Step-9-Version-2.jpg/v4-728px-Fix-a-Physically-Broken-Hard-Drive-Step-9-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Read this first. If the hard drive makes a clicking sound at the beginning, each time you connect it, it will cause more data to be lost because the magnetic layer on the drive is gradually failing. Do not self-repair if the data on it is important to you for business or legal reasons . Some of these techniques are “lucky”, with a 50:50 success – to-fail ratio. This means that if luck is not smiling, the unaffected pieces of data will not fly.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a4/Fix-a-Physically-Broken-Hard-Drive-Step-10-Version-2.jpg/v4-460px- Fix-a-Physically-Broken-Hard-Drive-Step-10-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a4/Fix-a- Physically-Broken-Hard-Drive-Step-10-Version-2.jpg/v4-728px-Fix-a-Physically-Broken-Hard-Drive-Step-10-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Conduct a physical examination. Hold the drive in your hand and rotate it back and forth, while listening to the sound (if any). It may sound like you’re “doing nothing”, but if something is really loose, this can cause “scorching powder”! If you don’t hear any sound, especially if the hard drive is old or getting pretty hot, it’s very likely the problem is with the spinning or coil bearing. Consider this risk before taking the next steps: if you disassemble the drive, the data that can still be recovered is likely to be completely damaged.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/77/Fix-a-Physically-Broken-Hard-Drive-Step-11-Version-2.jpg/v4-460px- Fix-a-Physically-Broken-Hard-Drive-Step-11-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/77/Fix-a- Physically-Broken-Hard-Drive-Step-11-Version-2.jpg/v4-728px-Fix-a-Physically-Broken-Hard-Drive-Step-11-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Warm up the hard drive. Preheat oven to lowest for about 5 minutes, then turn off oven. Place the hard drive in the oven for 2-5 minutes until it warms up. Note: although you don’t know if the hard drive is still usable, it is more likely that this will cause it to fail completely.
- Remove the drive and repeat the first step. If you still don’t hear any sound, proceed to the next step. However, if there is a difference, you need to insert the drive into the computer, listen for the normal spinning and clicking sound that indicates the hard disk is working. If everything looks fine, you can better access the drive and transfer the data to another drive.
- If necessary, warm up the drive again, then hold the drive in your hand, spin it quickly, and then tap it on a hard surface. This will help free the stuck hard disk (if successful). Otherwise, by now, you’ve ruined what could have been saved in the first place.
- Repeat the first step. Do you hear the hard disk move? If so, insert the drive into the computer and try accessing it again.
- If you hear a steady “click” sound with each movement, the hard disk may no longer be jammed. Check to see if there’s a rattle as you rotate the drive back and forth gently through 90-degree angles. If so, this is an indication that the drive’s internal components are loose and disconnected, which is beyond the scope and purpose of this article.

Hard drive cooling. Another controversial option is to freeze the drive. This is a last-ditch attempt to get the drive back up and running, long enough for you to copy your important files. If nothing works so far, this is well worth a try.
- Place the drive in a zip-lock bag and suck all the air out. Place the drive in the freezer for a few hours.
- Insert the drive back into the computer and try to access it. If the drive still won’t work, turn off the computer, remove the hard drive, and bang it on a hard surface like a table or floor. Then reinsert the drive and access it again. If successful, you can quickly save the data and then throw away the hard drive. If not, you’ve done your best and only need professional help.
