The internal IDE header of the A1200 can provide about 1 amp of 5V, not much more. I have a 2006 manufactured slim optical drive here that takes 1500mA of 5V, I wouldn't be happy running that without separate power... and I certainly wouldn't run it at the same time as a 2.5" hard disk that is powered through the same 44-way cable.
Does the label tell you what the power requirements are?
My drive is manufactured in 1999, but the power requirements are the same as yours: 5V DC , 1.5A = 1500mA. How did you power yours ? And yes, I have a CF hard drive going trough same time... I assumed that if the cd-drive worked on my Compaq without a separate power, it would work with my Amy. Wow im getting stupid :roflmao:
Opened my A1200 and found that there is a 2,5 44pin to 3,5 40pin adapter installed, since I have a CF hard drive, now I just need a 40pin female to 2xmale ide cable, is there such a thing? so my configuration would be : from 44pin to adapter, from adapter to CF and CD-drive.
