Error (261) when trying to backup purchases

Question

I have a new computer with SATA HD and SATA DVD burner (lightscribe) and am having a problem backing up my library.
When I insert a blank CD or DVD and select backup... backup entire library... iTunes goes off and checks the library and starts its 'burn' but then the CD ejects and a message comes up:
"The attempt to burn a disc failed. An unknown error occured (261)."
I checked that the drive is compatible (it shows under preferences/advanced/burning) as suggested by the online support docs... and the burner works with Nero & Alcohol... and I have not had problems backing up in the past. The things that have changed recently are the new CD burner (Asus lightscribe) and upgrade to version 7.3.1 iTunes.
Can I assume that I can 'manually' backup my library by just copying the library to another hard drive ? I just copy my itunes folder off to the second drive ??
Thank you all.

If you have multiple drives on the same IDE or SCSI bus, these drives may interfere with each other.
Some computers need an update to the ATA or IDE bus driver, or Intel chipset. If iTunes has problems recognizing CDs or hanging or crashing while importing or burning CDs, check the support site for the manufacturer of your computer or motherboard.
