I used above script – SQL SERVER – 2005 – Restore Database Using Corrupt Datafiles (.mdf and .ldf) – Part 2

and restored from the suspect data.

I will be thankfull to you.

I have a 2 TB database and the checkdb gave be below output
CHECKDB found 0 allocation errors and 949 consistency errors in database ‘PRD’.
repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (PRD ).
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

After running with repair_allow_data_loss, I got below output

CHECKDB found 0 allocation errors and 949 consistency errors in database ‘PRD’.
CHECKDB fixed 0 allocation errors and 902 consistency errors in database ‘PRD’.
repair_rebuild is the minimum repair level for the errors found by DBCC CHECKDB (PRD repair_allow_data_loss).
The statement has been terminated.

Please let me know how to repair the database completely. And is there any way to find out which datafile is most corrupted?

Thanks in advance…

I have an sql 2005 express db that has been corrupted. The end user has no backups so I’ve tried using DBCC checkdb and I get the following error:

SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x17b8ed1d; actual: 0x79d02a32). It occurred during a read of page (1:1957) in database ID 7 at offset 0x00000000f4a000 in file ‘C:\bytedownload\BYTE_SKU.mdf’. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.
During redoing of a logged operation in database ‘BYTE_SKU’, an error occurred at log record ID (15907:16:98). Typically, the specific failure is previously logged as an error in the Windows Event Log service. Restore the database from a full backup, or repair the database.
Could not open new database ‘BYTE_SKU’. CREATE DATABASE is aborted. (Microsoft SQL Server, Error: 824)

The dB was originally marked ‘suspect’ but I was able to set to Emergency/Single User. Now I can write Select statements against the tables but still the db is corrupt.

Any suggestions as to what I might try next?
Best Regards, Matt

After running this script i was able to browse the data and attach it to a SharePoint site.

Thanks.
