Terabyte drive connected to iMac 2.8 GHz dual core Intel by an 800 to 800 firewire hums but does not light up and is listed by the computer running Leopard 10.5.0 as unknown device, model and manufacturer.Computer does say max speed is 800mb/sec but connection speed is unknown. I think my connections are good and proper and I powered up as the last step. Apparently the startup software WD states is on the disc did not install the drive so I assumed I needed an upgrade for compatibility. I tried WD button manager software to no avail. I need help to find the proper software if indeed that is the problem. Thanks

The S.M.A.R.T. status is used to communicate information about a Hard Disk Drive.
Since your product is a DVD drive, it not does send S.M.A.R.T. information so MAC list it as "Not Supported" for that feature.
It is normal with a DVD drive and you have nothing to worry about.
if the drive is making the "Click of Death" then most likely the only way to recover the data is to send the drive to a data recovery specialist (DriveSavers, On-Track et al) recovery of data can be pricy.
It is possible the drive enclosure itself is bad, you could try moving the drive to another enclosure and see if it works there, but that is a stretch
Try resetting your PRAM to 'reset' your firewire-port:
- Turn off your iMac
- Press and hold command-option-P-R (command = applekey, option = alt)
- While holding this combination, turn on the iMac.
- Keep holding this combination until you have heard
the 'startup chime' 3 times.
- Allow your mac to boot up.
If this didn't work, try removing the power cord from your mac after turning it off, and leaving it unplugged for 15 minutes before turning it back on.
These steps usually work for me when I have a firewire-problem. I hope it helps for you.
Hi there mu names Mark. Lets see what I can do to help you. Firstly some really obvious things 1 Is the light on the external drive 2 Is the USB/Firewaire cable connected at the Mac and the disk 3 If so reseat it by pulling it out of both ends and replacing 4 Have you tried another USB or Firewire port something to be getting on with try those and re-post if no fix regards from England Mark
I picked up a couple of My Books lately( via Ebay), and noticed that i can not get them to work on the Firewire interface with my Dual Core Intel Mac. Shows up on USB2.0 fine however.I found an online reference that said Apple changed some things on the Firewire interface year or two ago, and that vendors had to update their firmware (it related to Firewire devices reporting a unique ID to the Mac).
The whining noise and the low clicking sound are indicate mechnical problem.
My recommendation to you is to backup all the important data you have on it ASAP before it will crash and you will not able to do it !!!!
there is not enough power coming through ports each device re-quires 1-5 volts to run and if your mac has not got enough power to boot all devices then sadly all things pluged into will not reconise and with mac the os is not properly designed for it now if you got yourself an external usb 2.0 hub powered then yes all devices will be seen in mac windows firewire is unsafe at moment for this to happen ask them what system they had had configuration on.
hope this has helped
