SQL Server stories are full of incidents in which the user faces several software and hardware problems which are responsible for making the SQL database corrupt. Errors indicate the diversion from the ideal work, which SQL server should perform. One such error is as stated below:
“Error 823
I/O error <error> detected during <operation> at offset <offset> in file ‘<file>’”
Microsoft says that this is with regard to either the system or hardware problems with SQL server. As the direct or indirect result, this situation can make you fall for SQL recovery, so be prepared for it.
Either I/O logical check failure or operating system error can be the prime cause of the stated error message in the logical cause’s category. While operating system error, if read or write Windows API call becomes unsuccessful, the 823 error may be generated. On the other hand, if this call comes out as successful and specific logical checks on the data are not successful, then this form the category of I/O logical check failure. Run DBCC CHECKDB statement and solve this issue and if still, the 823 error is being the headache, see the problem from hard disk problem point o view. In few of the cases, this may also happen that the database may remain logically corrupt, even after running the command, so use SQL repair utilities and proceed.
If this is the hard disk issue, which is responsible for the stated error, replace the hard drive or if, possible, have the correct measures. In error 823, the high chances are for the disk related errors. Get sure about the problem by checking the Microsoft Windows NT system event log for errors.
