The disk interface now appears to be powered constantly (LED at least slowly blinking all the time), but the drive itself spins down after a period of inactivity (LED goes from solid on or fast blinking due to access to slow blinking, and drive is quiet) + fixed new setup: as noted, changed disk-sleep preference => no errors. + new setup: 2017 iMac WD drive directly connected via USB cable to Mac USB port => intermittent "disk not ejected properly" warnings sometimes ejected the disk, which is a pain in the butt no data loss or other problems detected by Disk Utility + previous setup: 2009 iMac WD drive connected by Firewire cable to Mac Firewire port default sleep settings => no problems through years of operation disk completely asleep when Mac sleeps (LED off during Mac sleep) + external drive: WD My Book 2TB with Firewire and USB interfaces In my case, Preferences > Energy Saver > uncheck Put hard disks to sleep when possible solved the problem Not that that helps you fix your problem. Drive vendors will concentrate on new drives working with new Macs, not all possible combinations of new/old.
#My passport for mac will not eject and will not back up mac os#
It's not surprising that older drives or hubs don't work completely with new editions of Mac OS of new Mac hardware don't work completely. That's a lot of testing, possibly requiring firmware updates for the drives. Apple presumably relies on third-party vendors to test their own hardware. The mixture of symptoms speaks of some kind of race condition between disk sleep and OS sleep with various combos of hardware and OS. Some suggested fixes work for some people, but not for others. Some people see the problem intermittently, some all the time. Hardware and OS version vary, but the problem occurs mostly with USB-connected hard drives. There are many discussions about "disk not ejected properly" dating back years.
