No. There is no way for the PS2 to block out the Swapmagic discs, unless the discs were blacklisted (Which was never done so far).
If the Swapmagic disc (Regardless of the disc type) was inserted into the console and the disc does not boot successfully, it probably means that it is bad.
Yes, Swapmagic discs are known to go bad... unlike those pressed discs that you get from Sony.
