Detaching a portable HDD.

Win7. SP1 Norton Ghost15

I use an external HDD for off-site backups.

When finished I want to unplug this from the
computer.

Often the relevant icon appears in the tray but
sometimes it doesn't.

Is there some other way to detach a HDD safely?

IMO, the best way is to turn the power off first.

In Windows Explorer you may be able to right click on the drive icon and
get an option to eject

This seems to work only with thumb drives.

Is perhaps the system tray notification area (aka system tray) squashed
(because you elect to allow some icons to be hidden) and you have to
click on the chevron to see the remainder of the tray icons? Just to be
sure, does the tray icon not appearing mean it is also not a hidden icon
that you have to expand the system tray to see?

If the Safely Remove Hardware icon isn't there, you can load the
utility's UI by running:

rundll32.exe shell32.dll,Control_RunDLL hotplug.dll

Hmm, appears that doesn't list everything. Either go to:

Control Panel -> Hardware and Sound -> Devices and Printers

or run:

control.exe /name Microsoft.DevicesAndPrinters

In disk management there's a "disable" function.
Will this do?
I don't think "disable" kills the power to the unit.
How is the drive connected? USB, Firewire, IDE cable, USB/SATA?
Most USB drives have a "safe to unplug" command after data back
up to allow safe removal. It turns the power off for you.

Many thanks. The "Devices & Printers" showed the
HDD and it had the eject function too.

There is a freeware utility called Hotswap!
I use it all the time for these things.

power off and unplug.
And risk data loss because the OS wasn't done writing to the drive?

No thanks. Better to do it the right way and "Safely Remove" or
"Eject".

Doing so risks data loss if the OS isn't done writing data to the
drive.

Hi, Peter.

Microsoft made it hard to find the fix - and very easy to fix when we find
it. There's a slightly simpler path that I can't remember, so I usually get
there this way:

Run Disk Management (diskmgmt.msc). In the Graphical Display, right-click
on the Disk - in the far left column (NOT on a "drive", which really deals
only with a partition, not the whole physical disk) - then click on
Properties, then the Policies tab.

On Policies, there are two options, with a one-paragraph explanation of
each. For backups, especially large backups, you may have chosen (probably
by default) "Better performance". As it says, this uses a Write cache to
buffer transfers IN MEMORY on the way from the source to the destination
disk; an abrupt disconnect or power down can lose any buffered data not yet
written to the destination. The actual read/buffer/write process usually
takes only a few seconds, so the risk of such interruption is small - but
more than zero. This does speed up the backup - or large copy or move
operation - so it makes sense to use the buffer for these operations.

The other option, "Quick removal (default)", does not use the buffer (aka
cache); it immediately writes the data to the physical disk. Thus, anything
that takes longer than a lightning strike is not likely to lose even a
single byte. An abrupt disconnect will interrupt the process, but data will
be intact: unmoved data still at the source; moved data written at the
destination. So we can safely "pull the plug" - either power or data - at
any time.

For a more detailed and official explanation of write-caching, click the
hypertext link on that Policies screen. And note that you can click the
link under Better performance to set this policy for each of your removable
devices.

For my one-man one-computer situation, Quick removal works fine. I never
have to worry about unplugging my camera's SD card or a thumb drive. For my
USB 3.0 backup HDD, I just wait a few seconds after the light goes out - on
the rare occasions when I unplug it at all. I'm running Win8, but this
behavior has not changed since Vista or before.

Actually it's not a question of power but of removing a data connection
during a set of write operations.

To make sure, I just plugged a USB drive in and safely removed it. Its
power LED is still lit.

Plug it in.

If you mean after unmounting it or telling Windows to let you remove it
safely, then you have to unplug it first. Then replugging it will
remount it.

I think there might be free SW to do it without unplugging. Or not.
