TM LaCie XHD fails again

Question

Have 500GB LaCie d2 HD QUADRA from 2007 as my TM backup XHD.
3-2009 failure to mount & had to replace Power supply under warranty. Now same problem.  I read online many people have problems with LaCie power supply failing repeatedly.
Thinking of getting “G-Technology G-DRIVE 2TB Professional External Hard Drive”
Hoping it is better quality.
Then I plan to transfer my TM backups from my LaCie as follows:

Mac OS X v10.6: How to transfer your backups from your current hard drive to a new hard drive
If you upgrade to a new hard drive with a larger capacity, you may want to transfer your existing Time Machine backups to it before using it for regular backups.  To keep your existing backups on your new, larger backup hard drive, follow these steps:
          1.          Connect your new hard drive.
          2.          In Disk Utility, make sure it has a GUID partition and is formatted as Mac OS Extended (Journaled).  If needed, reformat the drive as Mac OS Extended with a GUID partition. If you do not know how, see the steps in this article.  Note: Back up any data on the hard drive before you format it.
          3.          Select the new drive's icon on the desktop and choose Get Info from the File menu.
          4.          Make sure "Ignore ownership on this volume" is not enabled.
          5.          Open Time Machine preferences in System Preferences.
          6.          Slide the Time Machine switch to Off.
          7.          In Finder, double-click the current backup hard drive to open its Finder window.
          8.          Drag the folder "Backups.backupdb" to the new hard drive.
          9.          Enter an administrator user name and password, then click OK to start the copying process.  This may take some time to complete because all your backups will be copied.
          10.          In Time Machine System Preferences click "Select Disk…"
          11.          Select your new hard drive, then click "Use for Backup."
Now, on your new hard drive, you will have all of your existing backups from the previous backup hard drive plus have more room for more new backups.

Of course, I’ll need to get the LaCie to mount b4 I can do this so I will probably need to buy a $35 new power supply & hope it works. I don’t know if I can open the LaCie & remove the drive from the case & recover the data as I’ve read others have done. Long, involved process. 
Any comments on quality of LaCie & failure of power supplies & quality of the G-Tech product for TM?

Answer 1

No comments/no interest in this topic.
As a courtesy I will update in case anyone with similar problems reads & wonders what ever happened? Was it is fact the LaCie power supply a 2nd time or did the XHD itself fail this time?
Yes, it was a 2nd failure of the crappy LaCie power supply. So I can confirm from personal experiences the repeated failure of the poorly designed LaCie d2 quadra power supply. That is one huge “brick” /converter/transformer.
Note: The LaCie blue light s/b steady when on & not backing up, when it backs up it blinks as it does when the power supply fails. Also you can put your ear near the XHD & hear it spin up. When p.s. fails you can hear it start to spin up for a few seconds & then stop & then try again & repeat & then it stops trying & the blue light starts blinking. The power brick’s green light remains on & steady whether it is good or has failed.
I am very disappointed in the quality of LaCie power supplies since I’ve now had two fail & think what I read online about how poorly designed they are is true. I will probably purchase a different brand of XHD,  such as G-Technology, & use that for my Time Machine backup. While no brand has 0 failures, the LaCie power supply issue makes this brand unreliable.
