Lacie disk on FW not sleeping after installing Mavericks

I'm having this exact same problem with my G-Technology G-Drive. Went to sleep just fine with my iMac running Mountain Lion.

Exactly the same problem here with my LaCie D2 Quadra on an iMac late 2007 with Mavericks. Worked fine with Mountain Lion now it does not stop spinning if i send the iMac to sleeping mode. Have to manually set the drive now to OFF for stopping it.

I too have noticed the same problem since upgrading to Mavericks. My La Cie Quadra drives connected by FW 800 do not spin down when putting the iMac (late 2009, 27" 2.8 GHz core i7) to sleep. Frankly, it does not seem like the internal HD spins down, as when I touch the keyboard, I don't hear it spinning up either, and the computer seems to wake immediately as if the screen had just gone to sleep without the computer going to sleep. Energy save system preference checked and "put ard disk to sleep when possible" is still checked.

Can confirm that this is an issue, and it's not only affecting LaCie drives. It does seem to affect FireWire drives in general.

Got three WD drives connected to my iMac, two by FW, one on USB. After installing Mavericks, the USB drive sleeps when the iMac does, the two FW drives stay awake.

Swapped out the FW cable for a USB cable on one of the FW drives - and now it DOES sleep.

So it seems like external drives in general, when connected by FireWire, won't sleep on Mac OS X Mavericks.

**yes right now there is a serious issue with many FW ext. drives, even though I've been testing many HD ext. as fine none have been FW

WD Mybooks FW seem to be 95% of those many reported affected

Until this is resolved keep FW drives off Mavericks recommended

peace.

Regarding my G-Technology G-Drive, I forgot to mention that it is a FW800 drive.

I read posts elsewhere on Apple Support Communities and other websites. Some recommended SMC reset and others zapping the PRAM. Neither worked for me.

What I found was that if I unmounted my external drives and unplugged the FW 800 cord from the computer that the computer would go to sleep normally when commanded to do so. I subsequently hooked the drives up to the iMac with a USB cable, and both the computer and drives go to sleep properly, though it takes 20-30 seconds after the screen goes dark for the drives to spin down, which is longer than I recall pre-Mavericks. The external drives do not wake up from sleep until they are accessed.

I rehooked the FW800 wire from computer to the drives, which are wired in series., keeping the USB connection to the drives hooked up and the sleep problem did not return. My impression is that the connection in use between the computer and external drives is USB presently as there is no problem with the drives going to sleep when connected in the above sequence. If I eject the drives and remount them with both USB and FW800 connections, the problem with the drives not sleeping returns.

Same here. Have three external enclosures (inXtron SK-3500 Super-S3) all connected via FireWire 800 and all of them do not spin down the drives neither on Sleep nor Eject since upgrading to Mavericks. Tested with three different Macs (iMac 2008, MacBook Pro 2009, MacBook Pro 2011).

Used to work with Mountain Lion.

Funny thing is, when connecting the external drives via USB they DO spin down on Sleep or Eject.

Only workaround so far - full shutdown.

Hope to get some fix soon.

FireWire and thunderbolt HD interfaces seem to be universally affected. I've seen no exemptions yet to same

I'll add my two cents because this is a serious issue for me - 4 external FW Drives, 2 LaCie D2 Quadra & 2 G-Tech, all connected in series using FW-800. Mavericks fails to spin them down when it ejects them, goes to sleep, or based on the 'put disks to sleep' preference in energy saver pref panel. The one exception is that it intermittently spins down one of the G-tech drives, the last in the chain, when it is not in use, although it does not do so reliably nor does it follow the disksleep time set by pmset.

Kinda takes away from the green direction Apple is trying to go....

Same here with LaCia D2 Quadra via Firewire. It is really a pain.

Can we officially open or boost a bug report on Apple? They should fix this a.s.a.p.!!!

I called Apple Care yesterday and made a verbal report of the bug.

Theyre working on it right now, you can be sure. 😊

Until then use a conventional USB drive for backup or archiving vital files, or if you dont have a USB spare HD, burning vital "cant lose files" to DVD blank media or dropbox, or private website server......etc

glad I found this post, I posted in another thread about the same issue. I'll take your advice PlotinusVeritas, and I'll swap the firewire cable for a USB cable while they work out the bugs. Also, this whole debaccle reminds me that it's a good time to make an additional backup.

One backup and at least 2 archives is minimum "ultimate security" of all vital data you "dont dare lose"
