The first answer was: Can the data be saved somehow if the hard disk goes bad?
Remember one thing - if you have not backed up your data, then you have leased those data. And that lease can expire anytime. And the data can go out at any time.
Now come to your question - how to save data in case of hard disk malfunction.
The possibility of recovering data and the cost of recovering depends on the type of damage.
We will discuss traditional mechanical discs here, solid state drive is a new technology.
Software problems
Problems such as hard disk partition being accidentally deleted, drive format. This problem comes due to user mistake or any other reasons. If there is a loss of data due to these reasons, there is a great possibility that the data is recovered.
You can also do recovery work under these circumstances. My suggestion would be that as soon as the problem comes in the hard disk, you should not tamper with it nor fill any new data in that hard disk. Otherwise it will be difficult to recover.
Easeus Partition Manager is a good recovery software. I have tried it by recovering.
Hardware Problems / Physical Damage
Such problems were caused by a malfunction in the head, platter (disc), motor, bearings, or controller of the hard disk. This occurs when the hard disk is not handled securely or the hard disk is about to expire.
You cannot recover by recovering them by yourself.
In most cases the hard disk head is broken. Apart from this, there are problems like motor failure, bearing wear and tear. Those with recovery will change heads and repair around 5000.
The hard disk has an electronic controller, which also gets damaged many times. This can be changed. I do not have the idea of spending
The most important thing is the platter which is the rotary. Data is stored in the same. Let me tell you that this part does not spoil quickly. However, sometimes some part of the platter gets spoiled due to excess wear.
While working at Larsen & Toubro, I had a hard disk recovery which cost 14 thousand. Many times it costs even more.
If you have good technical restrictions, then you can swap out the bad hard disk in a new hard disk of the same model. But the problem is that all this work is done in the super-clean room and if the work is not done by the expert then both the discs will be likely to fail. Never trust a hard disk opened by yourself.
Solution
Look brother, we and you are middle class people, some data is very important, but due to super expensive recovery, after the failure of the disk, it is better to keep the backup of the necessary data.
Google Drive nowadays gets 15 GB in one account. Create 10 emails and use them to the fullest. Quora is suffering from multiple accounts, not Google.
Nowadays, 1000 GB external hard disk comes in 2500-3000, you can buy it. Backups can be kept inside this from time to time.
The probability of failure of a hard disk is 4 to 5 years. This can happen even earlier. So be prepared.
Periodically check the health of the hard disk using the Smart Check software. Smart check function often comes inbuilt in laptop, if not, you can download the software and perform the check.
SmartCheck is very smart and guesses if the hard disk is going to be damaged in the near future. If found early, it will be easier to secure data.
The power of a good hard disk is up to 40000 hours. After this, the hard disk will start experiencing problems.
Similarly, how much and how much error has come, you will get all the information in smart check. Do a smart check and enter the data and see if something new will be found.
Thanks to you. saved my Hard disk.😉
