Vista - RE: Vista slow boot with USB external drive

Brand new system with Ultimate. 4 minutes to reboot or shut down. Here are
some of the errors:

This application caused a delay in the system shutdown process:
File Name : mobsync.exe
Friendly Name : Microsoft Sync Center
Version : 6.0.6000.16386 (vista_rtm.061101-2205)
....
Background optimizations (prefetching) took longer to complete, resulting in
a performance degradation in the system start up process:
Name : BackgroundPrefetchTime
Total Time : 30742ms
Degradation Time : 742ms
....
Session manager initialization caused a slow down in the startup process:
Name : SMSSInit
Total Time : 11200ms
Degradation Time : 1200ms
