Compatible Discs for HP DVD-RAM GH60L ATA Device...

[T-Star-Squared]

What types of discs are compatible with an HP DVD-RAM GH60L ATA Device?

I have tried using a CD-R to write files with this drive and it will not recognize the disc. I simply need discs that I can write files to for storage and access at a later date or on another computer. Can anyone tell me which discs (CD-R, CD-RW, DVD-R, DVD+R, DVD-RW, DVD+RW, etc.) I need to work with this drive?
