Solutions for SQL Server Error code 823

There might be plenty of errors that occur in SQL, such as error 800040E104, error code 10, etc. But, some SQL errors keep coming to the server again and again, and often make it daunting for users to resolve them. One such error is error code 823, which is a critical and complicated SQL error. This error can disturb the consistency of server files, and so it should be treated immediately.

Here, we will highlight the reasons behind SQL error code 823, as well as share valuable solutions that can be used to cure this error quickly.

Reasons for SQL Server Error code 823

Defining the accurate reason behind this error won’t be possible, but it generally occurs when SQL Server declines Input or Output command; simply, the server fails to accomplish an Input or Output operation.

The SQL Server makes use of Application Programming Interface or API to coordinate with Windows OS in order to accomplish these operations. However, if there are some conflicts with the API during an operation, the server instantly displays error 823. Now, this error could appear in two different ways — Operating system error and Output/Input Logical Check Failed.

And there could be various reasons behind the incompatibility between API and the server. Some of which includes:

  • Common user errors in the system
  • Hardware corruption errors that affect the data
  • System corruption errors
  • Virus invasion into hard drive where SQL Server is installed
  • Corrupt Database files that often make SQL Server inaccessible
  • SQL Server update or reinstallation
  • Inconsistency in system files
