I'm looking for a decent 500GB external firewire hard disk. I know I could build one myself, but I like having the warranty for the enclosure & the drive thru the same company. I bought a Seagate FreeAgent Pro with FW400 but had strange issues where files disappeared, but were read fine when I ejected and power cycled the drive. When connected to my Vista machine, I didn't have this problem, but it was connected via USB. For some odd reason it would auto power down the drive exactly 5min after non-use so the drive was constantly going on and off by itself. It annoyed me enough to stop using it. I replaced the Seagate with a OWC Mercury Elite AL-Pro. Having FW800, it seemed much faster, but the drive was much nosier. For silent cooling, there's no fan, but the drive itself was very loud. This was a Hitachi model 500GB. I'm preparing to RMA it. So here's my problem. I want a drive that runs on at least FW400 (800 if costs are not much more) and is as quiet as possible. I would be storing recorded tv shows & music on this drive. How bad are the failure rates on Western Digital? I remember the pc desktop drives dying in a few weeks to a month about a decade ago and have avoided them since. I plan on keeping dvd backups of any important files anyway but would like to avoid any issues if possible. I haven't been considering the Time Machine since in my experience it seems to be a really slow performing drive. I have planned on upgrading my network from the DLink DGL-4300 Gaming Router to an Airport Extreme by the end of the year. I wish the AE was mountable to a wall like the dlink was though. Any suggestions?
