I am having the same issue, but none of this has helped me?

Customer Question

I am having the same issue, but none of this has helped me? Now, none of my disks seem to be reading?
When I reboot, ONLY diskwarrior is loading... then when it does, none of my disks are on it? I tried holding rebooting with: "alt", then tried again with: "shift", then next time: "command + r, then: "command + option + pr +... none work.
I was able to get the "command + s" to work, then I typed in "drutil tray open" as you suggested... but that did NOT open the tray? I then typed reboot, that DID work.
But it put right back where I started? At Reboot.
So How did this happen to me? My fault. Here's what I did to get here:
I ran disk utility because my computer was working great, but not perfect as usual. (sigh)
Know that I have done this before, and without issue. I have also ran diskwarrior for many years, without issue.
This time though, I went to the local disk utility, standard on any mac and clicked 'verify disk'.
I got an error in Mac's disk utility program that said it could not verify the main drive. But my Mac still worked fine. I worked a bit more.
When done, I popped in diskwarrior, restarted my mac, held down "C"... (to boot diskwarrior)... and it all worked as it should. ALL disks were reading, I repaired them all... then quit disk warrior.
Here's where I messed up...
For the first time in my life, right after I quit diskwarrior, before allowing it to fully reboot to my desktop... I held command + alt +pr reset my perimeter ram 😐😑😶. Now, upon EVERY reboot, it only launches the disk... AND NO hard drive shows up.
Diskwarrior shows up in the drop down area, but nothing else. In diskwarrior, it tells me about the disk drive. Saying reads:
"Directory cannot be rebuilt, Diskwarrior resides in the disk."
"Directory cannot be replaced, because this disk is locked"
When I reboot with "alt"... the only drive that now shows-up is the Diskwarrior CD?!
- My keyboard is wired in to the tower
- I am running Snow Leopard.
- 4, 2TB internal hard drives
- 32 gigs of ram
- diskwarrior 4.4

I assume this is a MacPro tower?

1. Shut down the computer.

2. Unplug the computer's power cord.

3. Wait fifteen seconds.

4. Attach the computer's power cord.

5. Wait five seconds, then press the power button to turn on the computer.

6. Press and hold the Command-Option-P-R keys before the gray screen appears.

7. Hold the keys down until the computer restarts.

8. Release the keys. Immediately hold the ALT or Option key until you see a lit of drives.

I tried it, but this still only shows one thing, diskwarrior?As mentioned in the post, I did try resetting the perimeter ram, then I tried again rebooting via alt/option... that did not work. I did just try it in your order, but got the same result. See the Attached picture(s).I also enclosed another photo of what happens when Diskwarrior boots up too; where only diskwarrior is found... not any other drive?
Expert:  Mike replied 1 year ago.

IN the DW window when you click on the DiskWarrioDVD do you see any other drives in the dropdown menu? Also check the Hardware tab in that window. Did you unplug the computer from power too?

Customer: replied 1 year ago.
No, there is no other option or Drive appearimg in the drop down window. Nothing shows up in Hardware area either. The option to repair is greyed out. It's not detecting any other thing but the diskwarrior disk?
Expert:  Mike replied 1 year ago.

Did you unplug the computer from power too? Try booting from your Snow Leopard disk. Go to Utilities and open the Disk Utility.

Customer: replied 1 year ago.
I unplugged it. I did just as you said... it did not work.I cannot eject the Diskwarrior Disk to run any other disk either. I tried all the ejecting options: eject button keyboard, pressing eject multiple times while rebooting, safe booting and typing "drutil tray open"... and nothing. I cannot get a disk in there to reboot from?

OK it sounds like the is a serious issue with the SATA bus. I think you ned to have it looked at. Sorry

Customer: replied 1 year ago.
What is "SATA bus"...?
Expert:  Mike replied 1 year ago.

That is the bus that the drives and the DVD drive are connected to. It is very unlikely that all the drives failed at once so it must be the motherboard.

Customer: replied 1 year ago.
I go into apple and say what exactly? ("check the mother board?" or "SATA bus issue?" or what?Is there any 'manual' thing I can do, like remove the ram, unplug things, then plug them back in 'within the Mac'... ??
Expert:  Mike replied 1 year ago.

No it is part of the motherboard. Just tell them you can't see any of your drives and the DVD drive works but will not eject. They will know.
