BD-RE BH16NS40 (Blu-ray Internal Drive) Causing rEFInd Screen to Constantly Refresh

[Christoph Pfisterer]

Hello again!

Recently I acquired a new Blu-ray internal drive to replace an aging Mac Pro SuperDrive that was incapable of burning Blu-ray discs. Now I have replaced it with LG's BH16NS40 and whenever I open the disc drive at the boot screen, it goes crazy and starts constantly refreshing. This never happened while using the factory Mac Pro SuperDrive so I'm at a loss of how to fix this. Any suggestions?

I have some questions to help clarify this issue:

• Precisely what do you mean by "open the disc drive?" Do you mean whenever you highlight it in the menu, whenever you hit the Enter key, whenever you eject the disc tray (by what means?) or something else?
• Is it an EFI-mode or a BIOS-mode boot entry that's misbehaving (assuming you mean you're highlighting or maybe launching a boot entry)?
• Do you see the same behavior for any disc you use, or just some of them?
• By "constantly refreshing," I assume you mean that rEFInd begins behaving as if you were repeatedly hitting the Esc key. If not, please elaborate.
• What happens when you hit the Esc key in rEFInd without opening the disc drive?

1. Whenever I eject the disc tray (via keyboard shortcut) to put a disc into the tray and close it.
2. It's an EFI-mode boot entry. I have it set to delay by 1 second so all the drives have time to spin up.
3. It's for all discs...Mac OS X Lion, Windows 8, music CD, DVD, etc.
4. You are correct. It's acting as if I'm constantly hitting the Esc key even though I'm not.
5. It refreshes normally. I use to have a Mac Pro factory SuperDrive, but it didn't have blu-ray burning capabilities so I replaced it with this model. Ever since then, rEFInd has been behaving this way. I have used menuentry to hide a few drives because I only need 1 of the 4 to show up to boot the RAID. Also, the text screen is temporarily shown when I choose both of my two Mac partitions. I've hidden all Mac internal drives and used menuentry to make them options to boot from. Although this is a different problem, it seems kind of bizarre and perhaps it is contributing to the optical drive's behavior. Call it a hunch.

Sorry it's taken me so long to get back to you; I've been pretty busy.

I'm at a loss as to why changing the drive could have triggered this, but I suspect the MenuExit variable is somehow getting stuck and not reset. I've therefore added a line to reset it; let's see if that helps:
