MacBozo Nut Dood Registered: 04/20/02 Posts: 16628 Loc: Pinellas Park, Florida	My MacMini is not among those listed as needing the recent EFI update and optical drive firmware update that were needed to correct the optical drive from spinning up randomly. Mine has begun doing that. Think I should take a trip over to the Apple Discussion Forums? _________________________

Jim_ aka Reboot Registered: 04/21/02 Posts: 11411 Loc: Columbus OH	What format of disc is in it? Data, movie, etc. Does it do it with all formats of discs? Did it just start with the current disc? I know there was an update to address drive noise at startup and wake from sleep for SuperDrives, but I didn't think it was to stop random spin ups. I've seen that happen on all models, a search a lot of times causes it to spin up, so I always recommend not leaving a disc in all the time to reduce wear and tear on the drives. _________________________ AppleCentral Trivia MM-MCF Trivia Call the Doctor

None of the posted EFI and SMC updates will install - the installers state that my machine doesn't need it. _________________________

Just a wild guess. _________________________ http://davidbearphotography.com/ ==== It appears that autocorrect has become my worst enema. ---

Did you try resetting your SMC, or SMU, or whatever they call it on those? Does Console give any clue at the time it spins up? _________________________ AppleCentral Trivia MM-MCF Trivia Call the Doctor

#454782 - 11/12/09 07:00 PM It does seem to be the fan [Re: MacBozo]
MacBozo Nut Dood Registered: 04/20/02 Posts: 16628 Loc: Pinellas Park, Florida	When I came home from choir rehearsal and woke the mini, it was quiet. iStat showed the fan running just under 1500 rpms. After a while, as the CPU began to heat up, the noise became quite noticeable as it spun up to just over 1800 rpms. It is still running at 1926 rpms but has quieted down. It seems that it is noisy only when it first spins up and then quiets down after it has run at speed for a few minutes. _________________________

Also curious if Console reports anything. _________________________ AppleCentral Trivia MM-MCF Trivia Call the Doctor

MacBozo Nut Dood Registered: 04/20/02 Posts: 16628 Loc: Pinellas Park, Florida	I did the stick a CD into it and there was no change in sound even after I ejected the CD. I don't see anything unusual in Console. I do see a little entry that caused me to chuckle, though. That is when the computer went to sleep and when I woke it. _________________________

NucleusG4 MasterBlaster Registered: 04/19/02 Posts: 8399 Loc: Miami, Fl.	Hmmm... is that an Intel Mini? I ask because I don't see where there is a list of computer models that require that update... just that it's Intel models. http://support.apple.com/kb/HT3744 To help determine that it is the optical drive you could use this..also to help control it till you figure it out. http://discrotate.sourceforge.net/ _________________________ http://davidbearphotography.com/ ==== It appears that autocorrect has become my worst enema. ---
