CD0 Uninitialized

[jcaser1948]

Hi friends
 I've got this dvd  drive HP nx8220 slim 9.5mm IDE DVDRW DVD burner player CD writer
 connected to an Amiga 1200  system 3.9 BoniBonged
 I have a 4xEide  
  I have connected in the primary channel of the 4xEide_buffer  a CF card ,which is recognize as primary Master ATA CF Card and works perfectly
 The DVD drive  is connected to the secondary channel  of the 4xEide_buffer and is recognized as:
 Secondary Slave ATAPI HL-DT-St DVDRAM GSA-Union
  The HL_DT drive is always recognized as slave, independent of the position in the cable , so it is not possible to make a cable select and so making it Master or Slave
 If I make an Info it says “CD0 Not a DOS Disk”
 and I receive in the Workbench a shaddy CD with the caption
  “CD0 Uninitialized”
 Has anyone a suggestion?

It's possible the CF card doesn't like having a slave and expects to be the only device on the cable. Are you sure the CD drive works? It should be possible to make a Workbench boot floppy with the CD DOSDriver on it to find out if it works without the CF card installed...

The CF card is in the first channel  alone
The CD DVD rom is in the secon chanel.
The CF card is connected direcly by means of an Adapta.It works perfectly because I boot the system from her  and can do anything with it.
The CD/dvd is indepently connected to the secon chanel

... which is all well and good when everything plays by the rules... But the dual channel IDE in an A1200 is effectively a hack, and relies on certain assumptions to work. That being the case, are you sure you have the correct unit and device for your CD drive's DOSDriver? Depending on the adaptor it could be scsi.device unit 3, atapi.device unit 3 and so on. Amigas don't support Cable Select so if you are trying to use this it might also be an issue. I still think it's worth trying the CD-ROM by itself, maybe on the primary channel, just to make sure it's compatible and working.
