Hey guys, I have a cMP1,1 that isn't detecting a HDD at all. The HDD is detected fine in my external dock, and another HDD works fine in the same port. Suggestions?

Hello,

1) Have you tried looking for it with Disk Utility?

2) Boot from the recovery partition and see if Disk Utility sees it from there. (It will eliminate a whole of of variables from your regular login.)

Try with other machine if problem is same then go with disk utility.
I tried with my dock, I don't have another machine that can use this HDD that is easily accessible.

1. Yes, not detected, (even tried diskutil list).
2. Booted to the installer, also not detected.

The port works, I put my main, bootable HDD in there and it worked fine.

I've reset the PRAM twice and the SMC twice.
 
Hello,

Just to make sure: did you try to boot using the recovery partition, *not* to try and reinstall, just to access the disk utility from a "neutral" and safe boot volume.

Last thing, do you have an old Apple DVD you could boot with, using an older OS?

I do not have a recovery partition, long story, but I have a bootable copy of the OS X installer with Disk Utility on a USB pen drive.

I have a copy of Leopard, but no DVD/CD drive.
 
Ended up being a physical issue. Some odd coating on the DATA pins of the drive. A screwdriver and some alcohol wipes fixed that!
