This is my 3rd NEC 3550A from different vendors.
My MB is an old Asus P4S533. It has 2 Ultra DMA 133 port.
Port 1: One HD and one old Pioneer A104 DVD writer
Port 2: One HD and one OLD CD-ROM drive.
I use Ultra DMA133 cable on both ports. Pioneer works well.
Now I upgrade Pioneer to NEC 3550A. Nothing works. I cannot flash firmware, cannot write, can read. I read several posts and think I might have to use regular IDE 80pin cable to hook up NEC 3550A. Since I cannot change my HD layout (otherwise I will get ‘NTLDR is missing’ error), I have to install my spare Promise Ultra133 TX2 card and use regular 80pin IDE cable to connect 3550A to it.
Post shows that NEC 3550A is UDMA 2, which is correct (?).
Now I am able to flash firmware (I use 1.Y6 now). But, I still cannot write on top of either default firmware or 1.Y6. I tried DVD+R DL and DVD-R. I tried Nero 220.127.116.11, DVD Decrypter.
NEC 3550A is a much newer product than Pioneer A104. How come its compatibility is so bad?
Now I don’t think my drive is defective. Any ways to work around?
