I haven't seen anything in this thread that would suggest that the drives are from 2 different companies. Would you care to enlighten me as to how you arrived at that conclusion? I must have missed something.
I am not sure how he ciphered that out either, but they are two different manufacturers. The failing drive is an LG HL-DT-ST DVDRAM GSA-4084N and the drive in my machine is a MATSHITA DVD-RAM UJ-851S. I have thought about it some more and I am not going to swap the drives, I am just going to insist that HP replace the drive. I mean, it worked then it didn't. -- John Registered Linux User 263680, get counted at http://counter.li.org
