Abstract: Have you ever met data loss on the hard disk that can’t be read by computer? I think amount of people do have experiences of that, and I certainly was one of them before learned these knowledge of hard disk.
First, three situations for unreadable hard disk by computer, and how to fix it.
1. Physical damage of hardware
When you encounter with this, you should figure out if it is caused by the connection lines or the damaged internal hardware first.
Solution: If the unreadable hard disk was caused by the physical damage of hardware, you can take it to the professional computer repairer, as computer is a very precise electric equipment with a extremely complex internal parts, and it could become a scrap for a tiny misoperation.
2. The hard disk could be only found in the computer but not started normally
This case probably caused by the lack of operating system, as the hard disk can’t be used normally before formatted. Therefore, if it is a new computer and have not do any partitioning or formatting yet, it can’t read hard disk definitely.
Solution: The best way to fix this is re-install your system, or you can use the after-sales service, seeking help from the computer makers.
3. The new added hard disk could be read by BTOS except operating system
This situation doesn’t happened usually, and it most likely because you did not set master and slave yet.
Solution: Most of the new added disk are SSD disk, a kind of solid slate drive, added to the computer by professional technicians. And you could carry the computer to the professional repairer to fix this.
Second, three common reasons for data loss from hard disk
1. Human cases
Data loss from hard disk caused by human cases is a routine activity, for you could did a lot of error operations like format the hard disk or delete the important files by mistake, or put the computer in a humid environment and got hard disk damaged. You could suffer from these cases like data missing, unreadable hard disk or files can’t be opened caused by wrong operation. According to that, we should raise the awareness of hard disk protection, strict to the rules procedure during operation, and never damage the hard disk artificially.
2. Got virus
The fact that data loss from hard disk caused by virus is not exactly news, as the hard disk could be damaged in a short time once the computer got infected. If the virus is the primary cause leading to data loss, you could encounter with data missing or stop-working computer or hard disk. Therefore, you should run the anti-virus software regularly to clean you computer.
3. Natural damage
Natural damage means data loss from hard disk caused by natural disasters, as lightening, earthquake or flood could damage the internal parts of computer. Once the computer suffered from this, the hard disk could got hurt or unreadable by computer and the files could got messy codes too. So do not use your computer while lightening.
Third, method for data recovery from hard disk
1. Using data recovery software
You could retrieve data by using a data recovery software, like Hdata Recovery Software, a powerful, easy-to-use data recovery software, with it’s pro-data scanning core, could deeply scan the lost data and completely get it back, for avoiding of partly data recovery or unreadable of recovered data.
2. Search help from professional data recovery institution
Note that, when the hard disk lost data badly, like the hard disk could not be identified by the computer, you should go to the local data recovery center for help. And remember that, do not write new data to the damaged disk for avoiding of overwritten, that could effect data recovery badly.
