problem external drive Firewire 400
External drive Western Digital MyBook Pro 500GB, USB/Firewire400/Firewire800:
When connected with Firewire 400 the external drive starts/powers up together with Windows XP, as it should, but sometimes:
- it doesn't power up at all
- it powers up but is not visible in Explorer nor in My Computer
I already re-installed the software and drivers (the disk doesn't need extra drivers, drivers are for the WD button manager) while connected to USB, as it says in the manual. Shut down, remove USB and connect Firewire 400, reboot. Still sometimes the same problem.
When connected with USB (2.0) the drive functions without problems.
Does anybody have a clue?
