Broken Hard Drive

I recently installed a 200gb hard drive in my computer. I have Windows 2000 on my original 40gb hard drive. However, last night I noticed a few programs weren't working, then I noticed the 200gb hard drive wasn't showing up in 'my computer'. I tried restarting the computer and could hear the hard drive start and stop several times. Does this sound like my new hard drive is shot? I

First try this:

In Control Panel, open Administrative Tools > Computer Management > Disk Management

Does the drive show up in there?

Could be a flawed power or IDE cable.
