TSSTcorp SH-S222A

Hi Paul, only thing I can suggest is replacing the Optical Drive...

http://eshop.macsales.com/staticpages/Framework.cfm?page=superdrive/sdl_powermacg5.html

I'm having the same problem with a new Samsung SH-S222 LBEBS. Computer will never go to sleep
because the drive spins frequently and wakes things up again. Did you get an answer?

Thanks, Basie

I now have one in my G5, mine doesn't do that, I wonder what your Settings in the CDs & DVDs pref pane are?

Just stuff like "Ask what to do" "Open iTunes" "Open iPhoto" etc.

Looks like this all has to do with what you want to happen when you insert a disc.

The Samsung is activating with no prompting.

Is that what you mean? The guy at macsales told me to switch the slave and master little white
plastic thing on the back, which I did. Made no difference.

Hmmm, open Activity Monitor & Force Quit iTunes Helper, see if it sleeps then.

Is that a risky operation? If I force quit, what do I lose in terms of iTunes and how do I get
things back to where they were?


thanks=====

No danger really, and a Reboot will restart it again like always.

It constantly watches the Optical Drive to see if you inserted a CD, pretty silly in my book.

Talked to Tech Support at MacSales and they said it's possible that my G5 thinks
the Samsung is really a hard drive and keeps trying to activate/read it. I'm trying
a script from them: http://eshop.macsales.com/Search/displayFAQDetails.cfm?ID=241

I'll post the results when I know it has worked or not.

Great, do let us know, looks very interesting! 🙂

The fix from MacSales had no effect but this does: +Yes! If I leave a CD (data or audio or blank) in the drive, the computer will sleep automatically as intended. If no disc is in the drive, the computer won't sleep and every few minutes there is noise from the drive, similar to when the read head is checking if there is a disc there.+(from DaSwede ) Also: +I was having the exact same symptoms as DaSwede. My PMG5 Dual 2.0 would not sleep and every few minutes the disk drive would make a noise as if it was trying to load a disk.+

+Putting in a blank disk into the G5 resolved the issue. Hopefully Apple reads this thread and fixes the issue in the next update. We have obviously pointed out an issue with 10.5.8+ (from dankaos)

Thanks for the report.

how often does Apple provide a fix for this type of problem?

Doesn't seem likely. My G5 is five years old and Apple has moved on.

But...there are a LOT of G5's out there and it seems this problem will

continue to spread.

I don't expect a fix myself, but mine does not do that with the same Samsung drive.

Hello, I have installed the samsung drive as a replacement in my G5 - it will read CD's but not DVD's ??? tried tech support at Macsales and they suggest it could be a laser issue - any problems with the drive for you ?? thanks.

Hello, no problem with mine reading or writing DVDs, even DVD-RW, not sure if I've tried burning DVD Dual Layer yet on it, but it reads them fine.

At the Apple Icon at top left>About this Mac, then click on More Info, then click on Hardware>Disk Burning & report what it says, like ...
