I used to have an HP-9150i (my first CD Burner). I bought it from Office Depot and took it home and installed it and couldn’t get ECDC 4 to recognize it. Before I understood that it was ECDC that needed upgrading, I called HP and they laughed at me when I told them I had a 9150i. It wasn’t supposed to come out for another 2 weeks. But that’s not the real story. About 8 months later, the drive died. I called HP at about 9:30 PM CST and they promptly answered and told me a replacement would be out soon. Two days later, I received the replacement and sent the other in with no problems. However, HP sends refurbished drives as replacements. About 5 months later, just after the warranty on the original drive ended, the replacement drive died. And basically, HP told me where to stick it. They don’t stand behind warranty replacements. A recent purchase of a Dell system included a combo CD-RW/DVD drive and a couple months after getting the computer, the drive stopped reading discs alltogether. I called Dell and told them my problem and serial number of the computer. They told me the computer was still in Dell’s inventory along with the other 2 systems I purchased at the same time. If the computer’s serial number isn’t registered to you, you can’t get warranty support. 48 hours later, after calling Dell probably 10-12 times, they finally registered the computers under my name and I finally got to put in a ticket to have the drive replaced.
