Windows 7 1394 Firewire devices not working?
The 1394 FireWire driver was updated in the Windows 7 and some older 1394 devices may not be compatible with the new driver. The old driver is still available as highlighted here. This solved my initial problems with a Maxtor III OneTouch drive. See this site for details http://www.microsoft.com/whdc/connect/1394_Windows7.mspx
