Defraggler stops my PC from shutting down

[Glen]

Windows 7 Ultimate
Defraggler (latest version)
2T WD external HD

Whenever I use Defraggler to work on one of my drives the PC won't shut down until I unplug the USB
lead going to my external HD. Has anyone here got the same problem? Does anyone here have any
suggestion that I can try? The HD sentry light stays on when the PC is trying to shut down, so I can
only assume that something is being written to it. The HD might actually be in sleep mode. I don't
know and I can' t find anything on the web about it. Just asking.

It might not be Defraggler. I just resurrected a 3 year old HP with Win
7 Home Premium, and it has the same problem.

No software is installed, except what gets installed with the HP
Recovery Disks for the computer that I purchased from HP.

Clarification on the last paragraph, I purchased the disks from HP, not
the computer! LOL

And it's an HP computer and the disks are for that specific computer?

Yup. <grin>

No problemo. I just defragged the external, USB connected hard drive
then shut down and restarted my generic, custom built computer.

This is part of a more general problem, in my estimation, although your
problem seems worse than mine.

Generally the cause is a program that is accessing the drive, even if
it is not doing anything anymore, and I have been unable in general to
figure out which program is guilty.

Software is available to unlock USB drives, but I've never had luck
with them.

One thing I've done is to go to Disk Management and put the drive
offline - *before* you try to shut down.

But it may be easier. You might be able to just click on the icon in
the notification area and tell Windows to eject the drive, again
*before* you try to shut down.

I'd wonder if the drive is shared in some way.

Not here, by which I mean I never share my external drives.

I doubt that Windows will decide to share a drive on its own.

Here's a clue. I have used a backup program that seems to take
ownership of the destination USB drive, and will not let me unplug it.
Other backup programs don't do that.

Unfortunately, I've tried enough different backup programs that by now
I have forgotten which one it is, except that I'm not using it now

Maybe it was Casper or EaseUS Disk Copy (it's not EaseUS Todo, that one
is OK).
