RESTORE VERIFYONLY FROM DISK = C:\BackupFile\MoreData.BAK When trying to restore the db from backup, it is highly recommended to perform a RESTORE VERIFYONLY on the backup file to know if the backup is in a consistent state. Now let’s look at both these options: Restore database from Clean Backup Step 4: At this point, we are facing database corruption, and our options are to either restore the most recent backup or repair the database either by using SQL native repair commands or third-party tools. See other errors for cause.ĬHECKDB found 2 allocation errors and 1 consistency errors not associated with any single object.ĬHECKDB found 2 allocation errors and 1 consistency errors in database ‘MoreData’
Page errors on the GAM, SGAM, or PFS pages do not allow CHECKALLOC to verify database ID 8 pages from (1:72864) to (1:80879). Server: Msg 8998, Level 16, State 1, Line 1 Server: Msg 8966, Level 16, State 1, Line 1Ĭould not read and latch page (1:72864) with latch type UP. Possibly tempdb out of space or a system table is inconsistent. A failure was detected while collecting facts. Server: Msg 8921, Level 16, State 1, Line 1ĬHECKTABLE terminated. Check type, object ID and page ID on the page. Table error: Allocation page (1:72864) has invalid PFS_PAGE page header values. Server: Msg 8946, Level 16, State 12, Line 2 Running the above command, detected 2 allocation errors and 1 consistency error as shown below: Run the command as highlighted below and analyze the results: DBCC CHECKDB (MoreData) WITH NO_INFOMSGS, ALL_ERRORMSGS Step 3: Perform a data integrity check on the SQL database to make sure that data is not corrupt.
Below is a screenshot of the command to check and fix the F: drive: Run the CHKDSK utility on the disk in question and allow it to fix any error by using the /F parameter. That, in turn, would most likely fix the cyclic redundancy check error in SQL. Step 1: Since the root cause behind the CRC error is an I/O subsystem issue, it is important to fix the underlying storage issues.

How to Fix SQL CRC Error?įollow the steps in the sequence given below to resolve the error: I/O error 23(Data error (cyclic redundancy check).) detected during read at offset 0x000001ac1c4000 in file ‘C:\Program Files\Microsoft SQL Server\MSSQL13.SQL2K16\MSSQL\DATA\MoreData.mdf’. Server: Msg 823, Level 24, State 2, Line 1 When querying the database, you will receive CRC error on SQL Server Management Studio (SSMS) error pane. Scenario 2: The next scenario is when you are querying the SQL database and it stops abruptly with the data check error. 12:00:32 AM ERROR: Job finished (With Errors) 12:00:32 AM ERROR: Read on “C:\Program Files\Microsoft SQL Server\MSSQL13.SQL2K16\MSSQL\DATA\MoreData.MDF” failed: 23(Data error (cyclic redundancy check).)īACKUP DATABASE is terminating abnormally. 12:00:19 AM Creating backup of MoreData to C:\Program Files\Microsoft SQL Server\MSSQL13.SQL2K16\MSSQL\Backup\ When you encounter the error during a backup, you can revisit the SQL Server error logs to get more details on the error. Scenario 1: You may get the error when backing up a database. Occurrences of SQL CRC Errorįollowing are two scenarios in which you may encounter the CRC error: Regardless of the specific cause, the cyclic redundancy check error is a serious error and must be addressed immediately to avoid potential data loss or even total system failure.

What is CRC?Ī Cyclic Redundancy Check (CRC) is a data verification algorithm that computers use to check the data on storage devices like SSD, HDD, CDs, Magnetic tapes, and more. You may encounter CRC data error in SQL database when performing any of these actions:īefore we jump into identifying the root cause for this error and find its solution, let us first understand what does cyclic redundancy check means. The error message reads as:Įncountered error: Msg 823, Level 24, State 2, Line 1 Sometimes, an issue with the I/O subsystem can lead to Cyclic Redundancy Check (CRC) error. It is without a doubt a key component to SQL Server performance and availability as storage. SQL Server operations are highly dependent on the disk subsystem.
