About those vanishing cabinets...

At the beginning of CoS, Harry hides in the Vanishing Cabinet at
Borgin and Burkes.  Why didn't he get transported to Hogwarts?  The
other cabinet was not yet broken, since it was broken LATER by Peeves
(Filch: "That vanishing cabinet was extremely
valuable...") on Nearly-Headless Nick's prodding.

Or was the cabinet at B&B already broken in some way?

Or was the cabinet at Hogwarts already broken in some way before
Peeves got to it?
