firewire conundrum
An acquaintance of mine has recently lost many hours of video stored on external firewire drives using the Oxford 922 bridge chip-set with firmware version 1.02.
It seems that this was a known problem with panther, but has been corrected. If you installed an upgrade with your drives mounted, it could render them permanently unreadable. Has anyone else experienced this with 10.4?
Thank you. -

When using portable FireWire drives, you always have to be prepared to lose your media. With any drives this can happen, but it does more regularly with FireWire drives because many do not know how to properly care for them.
The biggest problem is that the untrained editor will not generally unmount the drive before shutting down. Even worse, they do not know they need to do this to prevent this problem. Everything can be going along just fine – then POOF – your drive won’t mount.
Not unmounting prior to shutdown may corrupt the B-Tree and could screw up your file structure. Usually, Disk Warrior can recover and rebuild the directory and the media will come back online – not always – but usually.
Hot patching and hot swapping may also create the same problem. Always a better idea to unmount, shut down, then disconnect.
People generally abuse their drives: don’t put them in a cool area, toss them around, give them adequate power.
They work great, but if you thrash them – they’ll screw you. Sooner or later.

Still on 10.3.9 here, but to add to Shane’s general FW points, I’ve found that when things do
go wrong, drive won’t mount, etc. it sometimes *will* mount on another computer, then will
when reattached to the other. I have some FW case that are USB/FW combos. If they wount
mount with FW, the USB generally still will, I then unmount it from the USB, shut it off,
and again I can then reattach under FW and will mount.
