View Full Version : NTFS spin down?

Dec 4, 2011, 05:10 AM

I am have put a NTFS formatted drive into my MBP optical bay using a caddy and have a SSD as my boot drive and OSX partition. I want to continue using NTFS as I have a bootcamp partition for work.

I have noticed the NTFS drive never spins down even though I have selected the option in energy preferences. I only want it to spin up when its needed. Is there any way to get to this to work? Or do I need reformat the drive with HFS+?

Many thanks

It's nothing to do with it being formatted for ntfs

Can anyone suggest why it doesn't spin down? Thanks

Make sure that your machine isn't using any file on it.

As its a NTFS disk I haven't put anything on it. Reading around on other threads this seems a very common problem with disk caddy HDDs. I guess the only other solution would be to swap the SSD and HDD around?

If you eject the drive in Disk Utility, it should spin down and stay spun down for the rest of your session. I think it wakes up when you sleep and wake the computer, but should spin down again fairly quick.

That's the behavior I get on my desktops macs, YMMV.
