Peter,

1. When you "turn norton off" it's actually still hook all opens, so
   significantly slow down things.

   Try to create exclusion rule to exclude your build directory from
   protection.

2. Make sure you have SATA controller in AHCI but not legacy mode in a
   BIOS, (make sure you have AHCI driver installed)

3. T500 should be SATA-III

4. T* series has an option to install extra disk to bay instead of DVD,
   adapter cost about $5 on e-bay, so you can try a new disk without
   destroying whole system.
