Solved External USB-HDD won't spin down after safe removal

Specs: Windows 7-64 Pro, i5-4670 / 8GB DDR3
Advice sought about a problem that's only appeared since a recent reinstall of Windows on my PC.

I have an external USB-3.0 HDD that I only power on when I want to do an occcasional back up, turning it off again when everything is where it should be. However since reinstalling Windows 7 Pro on a bigger SDD drive (all of my personal data is on the same spinning disk drive as before), the 'safely remove drive' feature doesn't work in the same, convenient way.

Previously, clicking the 'safely remove' icon would present the expected message that the device could be safely removed, before the external drive would power itself down within five seconds, after which I would pull the plug from the power socket.

Now clicking on 'safely remove' seems to work for the first part, returning the appropriate message, but the drive only keeps spinning. Only turning the computer off completely, or pulling the power to the drive itself, makes the external drive spin down completely.

I'm at a loss to think what settings are different from my previous setup that result in this - help please!

When using the Safely remove icon is the actual drive identified there, or just mass storage device?

Look at the properties section for the disk drive in Device Manager. There are options there that affect how the drive functions. The default setting in Windows 7 is to allow fast removal without using the Safely Remove Icon. There is also an option to improve performance without risk if you have a separate power supply powering the drive.

That's an odd one. When you disable the drive in Device Manager does it spin down?

Long shot is to right click the drive in Device Manager then use Uninstall. If it asks whether you want to "remove software" then say no. After reboot it should find it as new hardware and re-instate the software. This approach has often fixed weird issues.

Always pop back and let us know the outcome - thanks

Apparently that's something they deliberately started with Vista and continued with 7:

There's third party software called 'safely remove':

http://safelyremove.com/help/ht_pow...

that has an option to power down the device. There's also a registry modification:

that's supposed to do it too.

I just noticed he mentioned 'pulling the plug from the power socket' to stop it spinning. The links above may just be for devices powered from the USB port not the wall socket, although I guess we'll have to wait to see the results if he tries it.

Thanks for all of the replies, Dave and Derek. I've just tried the registry edit with no success, I'll let you know what results from further attempts after work today.

Just out of curiosity, did you try the disable in Device Manager and if so did it spin down then?

I find myself wondering "why" M$ decided to change a perfectly working procedure"?

If power to a usb port was previously disabled when the device was shown as may be (safely) disconnected..., why the need "now" to leave it powered?

I am confused with this post.

Question: When you say "spin down" you meant the external HDD has its own power adapter and should "spin down" when you "safely remove" it? If that is so, the Solid State Drive (SSD not SDD as you called it) may have something to do with it. Read this article...

@XPUser: What's a "Solid State Drive"?

@OtheHill: Thank You! Looking at the properties for the drive under Device Manager shows two removal policies to choose from, 'Quick removal', to which my drive was set, and 'Better Performance', where I have to disconnect the device safely. I changed to the latter and the disk now powers down upon safe removal. I'm hopeful that this might speed it up a little too.

@Derek: for science, I tried your suggestion of disabling the drive to check whether it powered down - nope! Many thanks for your advice though, much appreciated, as is that from Dave. Cheers!

Solid State Drive = no moving parts. The purist won't agree but its a bit like a whopping great flash drive. Plenty more in Google.
