I had/have a similar problem with my 420. You say you have the ide drive on the primary controller without any jumper setting. I had to set the jumper to MASTER for it to work. Is there another device on the second connector? If so, first try setting the drive as master and nothing else on the cable. See if that works. Then try adding the second device as a slave or no jumper setting and see if both device continue to function.

 

The other thing to try is select a type that corresponds to the 160GB instead of auto (although auto should pick it up.)

Hope this helps and let us know.

 

I'm having a similar issue with a Precision 340. Has one 18GB SCSI drive and I'm trying to add a 120GB IDE drive on the primary IDE controller. Secondary IDE controller has a CD-RW drive. Primary controller was empty, now trying to add the IDE drive to it. Can't get WinXP to recognize it. Have tried same BIOS settings as ryan_xorn and calbe select, master, slave settings on drive. What gives?

 

Only other thing I notice is a conflict in Device Manager between the Secondary IDE controller and the SCSI/RAID host controller, but I'm unable to change the IRQ settings (guess I need to check it in the BIOS).

 

Any ideas?
