Hi
I have Database in SQL-Server2000 size is 1.37 GB i am tryn to take backup followin are the problems:-
1. Maintainence Plan for Backup Fails for DB
2. Jobs fails for Backup

--> I goto SQL Server Logs Error message is Operating system error 23(Data error (cyclic redundancy check).)

--> Now i am tryin Backup using command :-
Backup Database 'DB1' To Disk ='Path' followin error occurs:-
"Nonrecoverable I/O error occurred on file"

--> Now i am doing back-up directly from Enterprise Manager following error message occurs same error comes

Whats surprising Jobs, maintainence plan, Backup for other database is working perfectly, i checked HDD doesnt have any bad blocks etc. i have even changed path for Backups but still only for these database it gives problem

With Regards

Kristen

Try:

DBCC CHECKDB('MyDatabaseName') WITH NO_INFOMSGS

and see if that reports any errors.

Ignore the other attempts - the backup command is the important one.
It's giving an error on the fikle which sounds like the destination file (but may be the datbase files I suppose).

What happens if you try to copy a large file on that server? (I assume it's a local disk?).

I had a similar problem and it turned out to be a cheap sata controller which couldn't cope with data streaming to the disk. Was ok for small files though.

==========================================
Cursors are useful if you don't know sql.
DTS can be used in a similar way.
