I purchased a Lightscribe DVD writer to experiment with creating some interesting DVD labels. I work on the Mac platform and normally most hardware/software combinations are simply plug and play. Not so in this case. I sent an email to Lacie seeking help. Their step by step solution fixed the problem. I’m providing it here in the event you are having the same issues.
Symptoms: I was able to write my data to my drive, but when I tried to print using the software that Lacie supplied with the drive, the software would not recognize my drive. I learned that there are four separate files that must be loaded in a particular sequence that the system needs to work. Following is the sequence of steps offered to me by Lacie support that fixed my problem.
Disclaimer: This article is written 7/13/2009. By the time you read this article, the software requirements, their versions, and the links I am providing may have changed or no longer exist. This article is provided as a courtesy to get you in the right direction for further inquiry.
“First, please ensure you are using actual Lightscribe-compatible media and be sure to put the media inside the drive gold-side (label side) down and close the tray before trying to print. If that doesn’t work please follow the instructions below for further assistance.
The following steps fix almost all Lightscribe software-related issues.
Step 1
Download the latest version of the Lightscribe Host Software and LaCie Lightscribe Labeler 1.2 from LaCie.com.  Also, go to Lightscribe’s website to download the latest system software.
Step 2
Find the existing LaCie Lightscribe Labeler in your Applications directory. Drag it to the trash.
Step 3
In the Finder go to /Library/Receipts (this can be done by double-clicking the Macintosh HD icon, double-clicking Library, then double-clicking Receipts)
Step 4
Delete the two entries that are lightscribe related. There are usually two, but if there are more, delete them anyway. A normal Mac OS install doesn’t have Lightscribe software pre-loaded.
Step 5
Empty the trash.
Step 6
Install the newer Light Scribe Host Software.
Step 7
Install LaCie Lightscribe Labeler 1.2 .
Step 8
Install Lightscribe System Software
Unless your drive is physically broken; this should fix the issue. A test burn should go through without any problems. If you continue having problems try the drive on a second Mac to confirm there are no software issues with your computer. Make sure you are actually using Lightscribe media with the label gold-side down in the drive. You might also check to see if the issue replicates on a second computer and swap out the data cable (USB or FireWire) as well.”
