External harddrive won't shut down in Mavericks

Hi all,


I have an external hard drive from which I boot OS X Mavericks on my iMac late 2007. In all previous OS X versions, the harddrive would shut down whenever I put my iMac to sleep. Now with Mavericks it won't anymore. It will constantly spin while the computer is sleeping. I have to completely shut down to make the harddrive switch off. Is anybody else expierincing this kind of problem, and does anyone know how to solve this?


Cheers

Oli

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.

I'm having the same issue. On iMac mid 2011 - OWC Mercury Elite Pro hard drive in use as Time Machine Backup connected via Firewire 800 will not spin down. I reset PRAM and SMC, repaired permissions and no luck. I also erased and formatted the OWC (mac os extended journaled) and deleted the Time Machine plist. Mavericks was a clean install. I have used this hard drive when Lion and Mountain Lion were installed on this Mac and there were no issues. I have another OWC Mercury Elite Pro hard drive connected via USB through a hub and it spins down with no problem.

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





Its happening on 80% WD Raid My Book on this board and others, and happening entirely on Firewire and Thunderbolt drives


Its seen on O Raid and 1 Raid both alike.



also occurring on LaCie (Seagate) FW drives.



until resolution , use external USB drives proven to work with Mavericks.
