    I have 2 LaCie 250 GB Firewire external hard drives connected to my 2 imacs (one on a G5 OS X Tiger and one on an imac G4 OS X). All of a sudden neither of my external hard drives are mounting to my desktop. I have other external hard drives (G-Tech and Iomega that are showing up on my desktops just fine).

    These hard drives have important audio files on them. How do I get them to mount?

    Thanks in advance for any help.

I support the comments of (fire sine) I have the d2 120gb Lacie and it was down for two years.  I took it to my apple guys and they said that I needed to go to a data recovery service which would cost a gang of money.  Come to find out, when I decided to update my internal hard drive on my Mac Pro, I had to buy a SATA, IDE, USB 2.0 adapter to back up the internal and transfer to the new internal. Long story short, something said, Hey try and open the Lacie and bypass the board in the enclosure and connect directly to the Western Digital drive inside.  AND WHALA! I got my info, so all I need is a new enclosure.

Have these drives ever mounted in the OS environment? I take it youre an audio producer, with a load full of expensive plug ins, being the reason youre still utilizing OS 9 after 7 years...... Lacie D2 drives in my experience are infamous for not having the most durable bridge boards. The bridge board is a chip that has a chipset on it which take the SATA or PATA connection and send it to the USB and or Firewire ports on the enclosure. If the drive is powered up, you should get a blue light on the front. When connected to either mac or pc ( porsches are MS_DOS formatted out the box ), if it does not mount or does not appear in DISK UTILTY, then it is a high probability that the enclosure/bridge board has failed and the drive ( if not making grinding, buzzing, clicking or beeping sounds) will have to be extracted and placed into a more stable enclosure. Hope this helps.

The icon for my lacie exyernal hard does not show

Here's two suggestions. (If your using Mac OS X 10.x)
Make sure external hard drives are to be shown by clicking "Finder" in the menu bar then "Preferences" and under the "Sidebar" section selecting "External Disks".
Also check that the hard drive is mounting by opening "Disk Utility" by first opening the "Applications" folder then the "Utilities" folder and double clicking "Disk Utility" and in the left sidebar checking to see if your external hard drive is listed as one of the mounted drives. Hope this helps, don't forget to comment/vote if this helped. Thank you.

How can I format an external lacie drive to mount on both a PC and a MAC without partitioning

You can not use the drive on both systems. It has to be formatted for one or the other. To transfer your files, I would either backup your files to CD's/DVD's or try to network your Mac and PC, then just dump your files to a share folder of some sort.

LaCie 500GB external will not show up on mac desktop. Blue light on, whirrs as if working but no icon on desktop (not mounted)

Did you format the drive using Disk Utility? Open "disk utility" from the dock icon or applications/utilities folder. Click the drive name on the left side of the disk utility window. click the "partition" tab in the window, next click the "options" tab and select GUID Partition scheme, or any Mac compatible scheme, read each explanation of the schemes. Name and resize your partitions, click apply. This is how it works running Leopard, not positive if the same applies to Tiger. I hope this helps you

External hard drive

500Gb Lacie D2 Quadra with the same problem of flashing led and not mounting on the desktop (Mac G4 Mirror), traced to the power supply (57w) going down on power, both 12v and 5v supplies are available but the main power to run the drive drops to below an adequate output, hence the clicking and whirring evident from the drive with simultaneous flashing led.

Testing with another Lacie power supply (250Gb D2) this time a 34w unit got the drive up and running, however, and this is the reason for this post, this lower power PSU failed a week later whilst waiting for a warranty replacement from Lacie (5 weeks and still waiting for the new PSU from them. they have no stock)

Message for all Lacie D2 users, check the power supplies first, test with another Lacie PSU, do not run the drive on a lower rating (34w) PSU it will fry it and leave you with another failed power supply.

If you are in a tight spot use the temporary power supply to move your data to another drive and get the correct 57w power supply before running the drive again.

Don't do as I did assume any Lacie power supply will run any Lacie hard drive, they won't, fortunately I had a second back up, but am 2 drives down and no new PSU's available to buy anywhere.

Try and purchase another spare 57w power supply, something all D2 users should do for long term security, as these do not seem to be very reliable and getting warranty support from Lacie on these is currently impossible.

The lack of 57w power supplies from Lacie and its distributors across the world is surely a warning to be noted!!!!!!

Buyers beware!
