What's the correct tsql syntax [SQL2008 r2] for RESTORE VERIFYONLY ...WITH CHECKSUM ?

I successfully backed up the follow DB WITH CHECKSUM and I believe I've followed the syntax for this correctly, but I'm not having any luck. If my syntax is wrong i'll gladly accept a knock on the noggin for the correct syntax. Or maybe my syntax is OK and the books online doco is wrong?

Here's my attempt WITH CHECKSUM:

RESTORE VERIFYONLY

FROM

DISK = 'Z:\foo\bar.bak'

WITH

CHECKSUM

,STATS = 2

RESTORE VERIFYONLY FAILED -- [<--from my print stmt]

@returnCode = 0 -- value of @@ERROR

@errorNum = 3013 -- value of ERROR_NUMBER()

@errorMsg = VERIFY DATABASE is terminating abnormally. -- value of ERROR_MESSAGE()

RETURN @returnCode = 3013.

Here's the other 'without' CHECKSUM:

RESTORE VERIFYONLY

FROM

DISK = 'Z:\foo\bar.bak'

WITH

--CHECKSUM

STATS = 2

18 percent processed.

37 percent processed.

55 percent processed.

74 percent processed.

92 percent processed.

100 percent processed.

The backup set on file 1 is valid.

RESTORE VERIFYONLY SUCCESSFUL. CONTINUING DB [bar] RESTORE. -- [<--from my print stmt]

@returnCode = 0 -- related postconditions

@errorNum = 0

@errorMsg = ''

Did it do a checksum validation w/o the 'WITH CHECKSUM' supplied? Or did it do this validation w/o the checksum validation? I tend to believe the answers are no, and yes, respectively. It would be nice if someone could confirm or refute this for me too.

thx
