I've had some bizarre Mac Pro behavior. Have noticed start up chime repeating when I reboot. Sometimes more than others. Using Time Machine to backup to a Drobo. And tonight installed driver for an HP Officejet J6480 connected via a USB hub. Computer stopped recognizing Drobo. I then disconnected HP printer and rebooted to seemingly normal (single start up chime) and also recognized Drobo.
Any ideas about why repeating chime? Does Mac Pro not like HP printer connected via USB hub?
I know...wierd.

Mac Pro, Mac OS X (10.5.2)

    Ditto. Have run Hardware Test, looped, and not finding any hardware issues.
    I also have a Drobo attached via USB, but no HP. It only happens on a restart, and the chime continues for 5-10 chimes, with each one sounding like it's been cut off, or the sound file is corrupt. It will ultimately boot, but not without the repeating of the chimes.

    Just recently, it's also started to completely hang in the middle of WOW - graphics stop refreshing, mouse / keyboard don't respond (though the mouse is moveable).

    I am getting this issue too. I also have a Drobo, and I disconnected it and still had the same issue. I also ran the hardware test without any issues.

    same strange phenomenon here - usually 2 chimes after startup, but not always, never more than 2. I do NOT have a drobo, nor any other USB or FireWire drive connected, no USB-printer at all. Monitor: Apple Cinema. Mouse: MightyMouse wireless via bluetooth. Graphics Tablet: Wacom (via USB). USB Card reader. Has anyone tried to reset PRAM or PMU or other thing that might influence boot behaviour? Power supply: switched AC-outlet - computer is always supplied with power, on power-up other outlets (e.g. monitor) are switched on.
    Any resemblances to your setups? I'll try disconnecting all cables (other than monitor and keyboard/mouse) before startup an see if there is any change...

    Has anybody resolved the repeating startup chime issue?
    I took my Mac Pro in to ProCare at a Las Vegas store. They said problem was fixed. Got home and reconnected computer. Booted up to a repeating startup chime.
    ProCare basically *****...but that's another issue.

    I recently purchased a new Mac Pro and have been experiencing the same problem. The curious thing to note is that I have a Drobo as well.

    I had the same issue but i don't have a Drobo (what is a Drobo?) but i discovered it seemed to be a power issue. I had a couple of external hard drives connected to my mac pro and it chimed around 10 times on boot up. I plugged my externals into my cinema display because that powers up after the machine initially powers up and it got rid of the multiple chimes and reverted back to one chime. Don't know if this will be to much help but i hope so.

    Your solution worked for me. I had multiple chimes when starting up my Mac Pro with the Drobo attached to the front side USB port. I plugged the Drobo in to the port on the rear of my Cinema display and now the Mac Pro boots up with its normal single bong chime.
