Error 1450 nonrecoverable I/O error occured on file when running dbcc or backup - bluescreen every night RRS feed

  • Question

  • Hi All

    I have a SQL 2005 instance with a db attached that is bluescreening every night when a SQL job runs.

    If I run:

    Backup database ACU_ABL_DW
    to disk='\\xxxxx\temp\ACU_DW.bak' with stats = 1

    I get the error

    Msg 3271 Level 16 state 1 line 1
    A nonrecoverable I/O error occurred on file "F:\mssql\data\acu_dw.mdf:" 1450(error not found)

    I also get a very similar 1450 error if I try to run:


    It sits for around 12-14minutes then returns the error:


    Msg 823, Level 24, State 10, Line 1 The operating system returned error 1450(error not found) to SQL Server during a write

    at offset 0x0000000ff80000 in file 'E:\MSSQL\Data\tempdb4.ndf'.

    Additional messages in the SQL Server error log and system event log may provide more

    detail. This is a severe system-level 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.

    I have searched high and low and nowhere can I find a solution to this problem.

    You can connect to the db, write items to the tables or select any of them - the files do actually exist on the disk and do have full read/write access

    If anyone has some suggestions as to what we can try, the db will not back up and will not complete a successful dbcc check so it seems impossible to diagnose the fault
