Paul Randal has some corrupted databases on the the SQL Skills site.

Answer 2

For a possible test scenario, drop constraints and/or triggers, corrupt your data (i.e. set former-foreign key references to NULL) then see if your script detects the corruption.

Answer 3

Get to the internal services and delete stuff that looks important. If that is not what you want then copy all the files onto a flash drive and repeatedly eject it incorrectly - eventually it will be corrupted. Then upload it back onto the server machine and check. But the likelihood is that your script will be corrupted
