So, I decided to replace my SCSI Plextor 8x CD burner with the NEC 3520a, and decided to try to install it myself. I'm not very good with hardware.
I took out the old drive and removed the SCSI ribbon cable.
Then, I put in the 3520.
Then I attached connected the 3520 to the same same ribbon cable that goes to the CD/DVD player that came with the computer.
Now, neither the 3520 nor the drive that came with the computer are showing up.
I went into Control Panel and did Add New Hardware. It found neither drive.
(I'm using a Dell 8200 with XP, and plenty of memory, etc.)
What did I do wrong? I'm sure it's something basic.
