What should I do if the hard disk can t be opened, and what is the reason why the computer hard disk

This situation is caused by a partition error. You reinstalled the system and destroyed the original partition structure. The partition structure is destroyed. Be sure not to write data to the hard disk. If you're not familiar with recovery operations. Don't mess around. will destroy the data.

Be sure not to repartition, format, or anything like that. In that case, the recovered data is incomplete. Maintain the status quo. To a large extent, the original data can be completely restored with proper analysis and processing. Without the need for data recovery software to scan the recovery.

If you simply use data recovery software to scan and recover, it will take time and the effect is difficult to say.

What is the computer hard disk suddenly not open, is it a prompt? You didn't even tell us the prompts, how do we know what kind of problem you are encountering now, and we can't accurately solve the problem in time for you to solve the problem as soon as possible. If it is caused by a crash that cannot be opened, it will not be opened for half a day, then in this case, I recommend that you restart the machine to test, and it still can't be solved.

If it is a prompt for the unformatted state, then in this case, it is necessary to consider whether the data value is enough to support the way that you can directly format the data to consume the data. Of course, if you want to save data, then you need to find data recovery to solve it, so you need to consider whether the value of your data needs to spend a high amount of ** to solve this problem. Of course, if you can't find the hard disk, then you need to confirm the boot option in the CMOS settings first, then you can check whether the hard disk is recognized, and the identification serial number of the hard disk.

Efforts to identify, then at this time it is necessary to reconnect the connection cable of the hard disk or reconnect the hard disk to rule out the test, which still cannot be eaten or the hard disk cannot be identified by external connection, then at this time, it is considered that the hard disk has been damaged and needs to be replaced, and at this time the value of replacement and data needs to be replaced. Of course, there is also the case where the hard disk is turned off in the CMOS settings. So in this case, we need to re-open the hard disk option in the CMOS settings for the machine to recognize and use it.

There are many factors in these situations, and you don't understand our specific situation now, so it is relatively general.
