questions on hard drive replacement and HD-DVD

I replaced my original HD with a 160GB but during the process, I couldnt take the screw off the metal cage so right I am just using my ps3 with the new HD plugged into the system without the supporting metal cage; is this going to damage my ps3 in the short run while I figure a way to separate the metal cage?

also is ps3 capable of playing HD-DVDs or only DVD/blu?

Without the hard drive being bonded to the chasis because the cage is missing, a static charge could cause problems.

I wouldn't operate the drive like you have described. JMO of course.
