Preface
Recently, many friends have been looking for Xiaobai and want to recover the lost data in the hard drive. They said that the computer didn't know why, and suddenly it couldn't turn on, and after some testing, they found out that all the data in the hard drive was gone.
Why does the data of the hard drive disappear for no reason, and can it be restored normally after reinstalling the system?
This is something that many friends want to know.
First of all, let's understand one thing: computer hard disks are divided into solid-state drives and mechanical hard disks.
Under normal use, the hard disk will not be easily damaged, but no one can say for sure this kind of thing. After all, manufacturers will mark one thing when selling hard drives:
That is to say, hard disk sellers will not help customers recover important data in the hard disk, so inform consumers: you must pay attention to backing up the data in the hard disk.
HDD
There are many reasons for the damage of mechanical hard drives, such as: accidental drops, high temperatures, reaching the design life, etc.
But for mechanical hard disks, if the mechanical disc in the hard disk is not broken, the data can basically be recovered normally. (Except in exceptional circumstances)
Solid state drives
Xiaobai wrote about SSDs before, and the problems mentioned in it will basically lead to data loss in SSDs.
- For those who use SSDs, please note that hard drives are easy to break without this thing!
This is not to say that the probability of damage to SSDs is greater than that of HDDs, after all, anything will break if you are not careful. However, once the SSD is damaged or data is lost, then the possibility of recovery is very small.
Why is the data on the hard drive missing for no reason?
Hard drive data loss has been encountered many times. It doesn't happen for no reason, but for a reason.
The data loss of the SSD may be caused by the failure of the particles, the main control, or the working temperature is too high, and once the data is lost, it is basically impossible to get it back.
Data loss from an HDD can be due to the aging of the HDD, wear and tear, or the bad sectors of the HDD itself. After data loss, don't panic, don't write anything to the hard drive, and hand it over to a professional data recovery personnel, the possibility of data recovery is still very high.
Can files be restored after reinstalling the system?
For the score of this question, it mainly depends on the storage plan of the computer. Xiaobai can't say that it can recover 100%, but it doesn't mean that it can't be recovered 100%. After the SSD data is lost, if it can still be used after formatting, it is recommended not to reinstall the system first, but try to connect to another computer for file recovery.
Why don't you reinstall the system and then restore the data? Because the process of reinstalling the system will write data, which may cause important data to be overwritten and cannot be recovered.
What is the best storage solution for a computer?
Having said so much, it is estimated that many friends have understood that the better storage scheme for computers is: solid state drive + mechanical hard disk.
After all, SSDs have a smaller chance of data recovery, while HDDs have a greater chance of data recovery.
Some friends may say: I don't have a mechanical hard disk interface on my computer, how can I form a storage solution of solid state drive + mechanical hard disk?
This one is very simple, just buy a portable mechanical hard drive as a daily backup.
How to save data more safely in daily use?
It is recommended to back up important files to the mechanical hard disk, and if you still feel unsafe, back up one more to the network disk
