Thanks Geke, I have a kit in the mail that Bruce suggested. When it  
arrives I'll try to make it work. I already have the drive out of the  
case. I'll let you know. Appreciate your interest.

Re: External drive fails to appear on Desk top?

[Geke]

Then what can be the difference between the two systems, the one on
the old drive and the newly-installed one?

Can you try the drive on another computer? Or do you have a clone of
that old system you can boot from and see if the drive appears with
that one running?
Or does this HD need some driver software to be installed?
Or, if the Network setting for the Firewire port is off, could that be
the reason?

Just guessing... I hope someone recognizes the situation.

In the worst case, you could always take the HD from its enclosure and
connect it in a different way, like USB, with that device Bruce
suggested, or internally if you have the right connection/adapter.

Yes. Please excuse my delayed response.

 Firmware Revision: 0x102


This is a firmware issue with your enclosure. It was a known issue of  
the Oxford 922 chipset when it was issued back in 2003, and has been  
fixed since then. See:




This article mentions 0x105, but I believe there are even newer  
versions since then? Lacie issues updaters, but they're hard to find  
on their site. MacUpdate is best for finding these:




I've always used the generic Oxford updaters on my Lacie drives, which  
will install the latest firmware which will function normally, but  
they'll change the name from Lacie to Oxford.

I completely misunderstood. I thought you said you had put another 
drive in the case. If it's the original drive and Disk Utility 
doesn't see it at all, something is either wrong with the enclosure 
or the hard drive.


or the power supply.

Stick your ear on the power supply ... is it dead quiet or do you 
hear humming or crinkling noises.  A well working power supply should 
be dead quiet.

System Profiler will show the volume as well, if it's mounted.

If Disk Utility doesn't show it at all, something may be wrong

Make sure the drive is plugged in all the way, sometimes it's hard

Thanks Bruce,
This particular model of LaCie appears to be in a sealed case with  
no access to drive jumpers. Any suggestions? Have replugged cables.  
Drive is about three years old.


No drive case is sealed.  Some are just tricky about how to open.   
You could try doing a web search on "opening lacie".  LaCie is a  
popular drive and it's quite likely someone posted instructions on  
how to open it.  If not a little probing should solve the puzzle.

I completely misunderstood. I thought you said you had put another drive in the 
case. If it's the original drive and Disk Utility doesn't see it at all, 
something is either wrong with the enclosure or the hard drive. They have to be 
tested separately; get one of these; they are the best tool we have in the kit:



Best $13 I've ever spent for computer gear, has saved our butts more times than 
we can count.

Numerous guides to disassembling these things exist:

External drive fails to appear on Desk top?

[John Callahan]

Drive appears in System Profiler but not on the desktop?
 Was using LaCie Porsche as a back up drive as a general precaution  
and as computer hard drive was starting to fail. Installed new  
computer hard drive. I shut down the computer, turned off the LaCie  
external drive and then unplugged the firewire cable. I then  
installed new hard drive in the computer and tried to start up on the  
operating system that I had installed on the LaCie drive as I was  
using the external drive for my main drive. A screen came up with a  
icon of a file with a question mark in the center of the file icon. I  
allowed this condition to exist for five minutes or so  and then  
installed a new OS  10.4.11 from my computer disk and the new system  
loaded and I was able to start the computer.  Checked the System  
Profiler and found this on the profiler:


FireWire Bus:

Please help as I have the work of years loaded on the LaCie back up  
drive.

Thank you so much.
