Intel X25M hangs on shutdown/logout

When I had just installed the Intel X25M (80 gb G2) shutdowns took merely 2 seconds. Now, after the dock minimizes adn hte icons disappear, the computer just hangs for 10-15 seconds, turns into a blue screen and hangs for maybe 10 seconds more before actually shutting down (black screen, everything off).

Does anyone know what is wrong? The drive is only 2-3 months old, and I still have 40 Gb free.

I was thinking it is some program that is running in the background that is having trouble quitting.

Anyone have any suggestions?

 

I tried that, it didn't work. Still hangs before shutdown.

It seems to repair the disk, but when I repeat teh process, it has to repeat teh same steps. When you repeat the process, does it stay fixed?

Startup is still fast (~33 seconds). When it was new, startup was 30 seconds.

Shutdown now is 17 seconds compared to 1-2 seconds when the X25 was freshly installed.

 

Here's a shot of what it shows when I repair the disk permissions:

I did the repair back-to-back and it just repaired the same thing, which seems to indicate nothing was fixed the first time. It seems to be mostly in a Java Folder.
