1. Can any of your 3.5" / 5.25" drive cases be powered via USB / Firewire bus power alone?
No. It is not possible. The 3.5" / 5.25" drives need two voltage supply: 5 V and 12 V, and the USB and Firewire bus can only supply 5 V. Furthermore the USB/Firewire bus power is limited to 500 mA (5 V)which is not enough for the 3.5"/5.25" drives.
2. How to avoid hard drive crash / how to maintain the external hard drive?
Hard drives are delicate machines, they are prone to vibration and shock, especially when they are powered because they are spinning at very high speed (7200 RPM), vibration and shock can cause the reading head dip into the magnetic surface, which may damage the reading head as well as the magnetic surface (bad sectors).
