am really pissed!

got a new 500gb lacie fw drive; hooked up with three other fw drives.
BEFORE this new drive, i could switch on any drive, or combination, and they'd mount on my mac.

with the new drive, the other drives WILL NOT MOUNT without this one being turned on... if i turn it off, they all unmount.

lacie tech support says that 'designs change periodically', and that this one works
correctly.

does any of that make sense?? do others who use several fw drives have this issue??

That's been the norm for me. If a drive (or external CD/DVD drive) in the chain is powered off, all other drives/devices after it will unmount or not be mountable to begin with.

Varies by device... some will stay 'on enough' when off to pass through the data, others are really off.

I have a pair of FW drives—NewerTech Ministack v2s, to be specific—daisy-chained, and if the 'middle' drive (the one between the second drive and iMac) is turned off, the 'outside' drive is unmounted. I never considered this to be a particular problem, to be honest, and I think it's probably pretty normal behaviour, so I wouldn't term it an issue as such.

with the new drive, the other drives WILL NOT MOUNT without this one being turned on... if i turn it off, they all unmount.
How have you got them set up? I imagine if it the first one in the chain (the one connected to the Mac), then that'll be why it's killing everything else when it goes off. My advice would be to try moving it out to the 'end' of the chain; that way, if you turn it off, it shouldn't unmount any of the other drives, and you should be able to mount it without necessarily powering up the other drives as you did previously.
