I just bought two of these at the TigerDirect store. They are attached to the Secondary IDE on my mobo. At first they both worked just fine. But then one day Nero 7 crashed while burning on the one set as Master. Now, the one in the middle of the cable (the slave) seems to be working just fine - but the Master at the end of the IDE cable just lights up, the drive tray won't open - it stalls my boot up and windows loading unless i press the drive's eject button (but the drive never ejects)
Also...orizen:[QUOTE=]I have backed up data with almost 15 dvd-r's with a NEC ND-3550A and my new 7170A won't read them...[/QUOTE]
I've had the same exact problem....I had an NEC ND-3550A and did several DVD backups on it - then they wouldn't read in that old NEC that burnt them or in several other drives. They would work in my old laptop's DVD-ROM drive, and maybe in a Lite-on DVD+/-RW I had, but for the most part - they wouldn't work anywhere else. It's STILL VERY FRUSTRATING when I know (and I can see) that something's written on several of those discs, but I can't get them to read. I really wish I had a solution for you, but I've not found one yet myself.
I had this same problem on my old NEC ND-3550A and now it's happening on my new Sony NEC AD-7170A set as master - yet the identical AD-7170A as Slave is working perfectly.
