my backups started to fail periodically with the following errors:
Nonrecoverable I/O error occurred on file 'd:\Microsoft SQL Server\MSSQL\Data\commodity\commodity_data.mdf'.
[Microsoft][ODBC SQL Server Driver][SQL Server]BACKUP LOG is terminating abnormally.
Or
[Microsoft SQL-DMO (ODBC SQLState: 42000)] Error 3202: [Microsoft][ODBC SQL Server Driver][SQL Server]Write on 'D:\Microsoft SQL Server\MSSQL\BACKUP\bx01t\bx01t_db_200901261049.DAT' failed, status = 2. See the SQL Server error log for more details.
[Microsoft][ODBC SQL Server Driver][SQL Server]BACKUP DATABASE is terminating abnormally.
Error logs show this:
2009-01-26 10:13:38.35 spid6 Error: 823, Severity: 24, State: 3
2009-01-26 10:13:38.35 spid6 I/O error 2(The system cannot find the file specified.) detected during write at offset 0x00000059594000 in file 'd:\Microsoft SQL Server\MSSQL\Data\commodity\commodity_data.mdf'..

When ran DBCC check db got 0 errors.
Any help will be greatly appreciated

That looks like problems with the IO subsystem. Possibly intermittent right now.
Check the windows event log for anything indicating hardware problems, check the SQL error log, check any logs from your drives.
Consider getting a copy of that database elsewhere. Hard IO errors and no backups are a very risky combination.

Thank you, I checked event viewer and found these warnings Event Type: Warning
Event Source: Disk
Event Category: None
Event ID: 51
An error was detected on device \Device\Harddisk1 during a paging operation.
And also that disk D has problems. But when our IT ran chckdisk on it it repported 0 errors.

Still, if it's giving errors there's a problem. You don't want to find the problem when the drive fails completely. It could be an intermittent IO problem at the moment.
Is this part of a RAID array, or is it just a single drive? Can you move the database elsewhere?

Asked our IT where I can copy my dbs from drive D. Don't have anything available there yet. But in your opinion there is no way to repair the drive?

It started with one db1 backup failure, then It worked for a couple of days, now this db1 (full and trans) and other db2 (full) are failling. But still there some not failing backups, even the trans backup for db2 is working.

No idea. I know databases, not drives
That said, from those errors it appears that you have one drive that's completely failed, and maybe some problems with the controller or other drives. Get those disks replaced! It's pointless trying to fix backup errors when the underlying drives are failing.
Do a backup somewhere else (removable drive, network, anywhere else), then get your IT people to fix those drives, before another drive fails and you lose the database completely.

Thank you, that's what I am on now, making IT to move faster to give me other options, thanks god it is only testing environment.
