Bye bye, external hard drive

A couple of days ago I salvaged the HD from a laptop with a dead mobo and
put the drive into a SATA/USB3 enclosure.

All is fine except when I hibernate the computer which I frequently do.
After coming out of hibernation Windows 10 has lost the drive; i.e., file
explorer does not show it, ditto disk management , ditto Device Manager
(should show under "drives"). A reboot brings it back to everywhere it
should be. Aparently, necessary info about the drive isn't being written to
the disk file used to come back from hibernation,

Does anyone have an explanation? A fix?

Thanks

You say SATA/USB3 enclosure. Does this mean you are plugging this into
your available USB3 port in your computer? If NOT then this could be
the reason otherwise, when you Sign Out from the account and Sign In
again, does it show? Perhaps worth a try and let us know.

what is the make and model of the enclosure?

Nothing is written into the hibernation file (hiberfil.sys) from any
drive other than the one where is the partition for the OS.

More likely is that you leave the USB HDD attached. When resuming from
hibernation, there is no event showing the USB HDD got attached. It is
still attached but no event telling Windows that is so. Rather than
reboot Windows to detect the new device, what happens when you resume
from hibernation and then unplug and replug the USB HDD?

Hibernation means restoring the memory image back into the system RAM.
It does not go around scanning for new hardware to poll it and the USB
device is not going to issue its presentation data to announce its
presence since it is still connected.

Beside unplugging and replugging the USB HDD (after resuming from
hibernation), have you tried rescanning for new hardware? Run Device
Manager (devmgmt.msc), right-click on the root node for your host, and
elect to scan for new hardware changes.

One possible scenario (this happened to me yesterday):

By chance do you have or had a WDC My Book connected to that computer? If
so, there's a virtual CD that contains the locking software that makes a USB
drive disappear. Once an eject command is issued by that software or some
other app you may have, that’s the condition you're experiencing.

Yes, it plugs into a USB3 port; however, Device Manager shows it under
:drives", not "USB".

Sign out/in does nothing

The enclosure is a Sabrent EC-UM30

Yes, I leave it plugged in.

That is also true for my USB3 thumb drive with which there is no problem

Nothing

Hibernation means restoring the memory image back into the system RAM.

Somehow, I would expect connected devices to remain connected. If you had a
desktop with two physical drives would you think the second would come up
missing?

Beside unplugging and replugging the USB HDD (after resuming from

Manager (devmgmt.msc), right-click on the root node for your host, and

It finds none. Not for drives, not for USB.

I have had a WD My Passport connected in the past, does that count?

If so, there's a virtual CD that contains the locking software that makes

Does the virtual CD show in Explorer? If so, I don't have one.

Yes the virtual CD shows for the My Book software. I haven't a clue about
the Passport.

Could also be a problem with controller inside the USB enclosure. The
salvage drive uses IDE or PATA/SATA. To connect via USB means there has
to be a PCB inside the external enclosure to perform translation of
hardware protocols.

Is the salvaged HDD a "green" device? Those sometimes don't wake up
when converting through USB but are okay as interal storage media.

Is the USB drive connected directly to a USB port on the computer case
or does it go through a USB hub? If through a hub, try going direct to
a USB port on the system case.

Does the USB attached drive provide for its own power (via A/C power
adapter) or does it get its power from the USB port to which it is
attached? When going into sleep/hibernate mode, the USB port are
unpowered which means a USB-only powered drive will lose its power while
the computer may not. It is not sufficient to look in Device Manager
under Drives since that USB-attached drive is a USB device. You have to
look under the USB devices to find which one is for the USB-attached
drive. Remember that this is a USB device now that you put it in an
external case and are converting its hardware protocol to USB. See:

http://digital.ni.com/public.nsf/all...2573A700602459

If the USB drive gets its power only from USB ports (i.e., no A/C power
adapter to the USB enclosure), are you sure that a single USB port
supplies enough power, especially for surge on startup, to startup the
USB drive? You mentioned that you used a SATA/USB3 enclosure but do you
connect that USB-attached drive to a USB3 port on the computer case? Or
are you connecting it to a USB2 port (which supplies only .5A max)?

I tried the first suggestion there, no difference.

I couldn't try the second because Device manager HAS no tab for Power
Management for the device. However, after enabling "hidden devices" in DM,
the drive shows as hidden (if it has disappeared from file explorer). Tried
uninstalling it via DM, shutting down, plugging in; same effect, disappears
after hibernation.

The naughty drive and the well behaved thumb drive use exactly the same
drivers.

I have no idea what a PCB is. I didn't pay that much attention to the
innards of the enclosure; basically, two plugs to the drive, one power,
other SATA, those hooked to the USB. I'm sure there is more to it than that
but regardless of what is there, why would it work always on reboot and
sleep, never on hibernate or shut down?

No idea what a green device is but same question... why would it work always

attached? When going into sleep/hibernate mode, the USB port are
unpowered which means a USB-only powered drive will lose its power while
the computer may not.

Power via port.

----------------------

It is not sufficient to look in Device Manager
under Drives since that USB-attached drive is a USB device. You have to
look under the USB devices to find which one is for the USB-attached
drive. Remember that this is a USB device now that you put it in an
external case and are converting its hardware protocol to USB. See:

In my DM the only USB listings are for the USB controllers; the USB drives
are enumerated under "Portable Devices" (and Drives). There are a couple of
USB under "Human interface devices" but no way of telling what they are.

---------------------------

If the USB drive gets its power only from USB ports (i.e., no A/C power
adapter to the USB enclosure), are you sure that a single USB port
supplies enough power, especially for surge on startup, to startup the

It is connected to a USB3 port. One of those pretty, sky blue ones

I have tried switching ports, I have tried unplugging the other USB devices
save my wireless mouse receiver which is in a USB2 port.

Thanks for your interest.

A USB3 port should provide ample amperage during surge to spin up the
platters, especially for a laptop HDD.

Since it is a SATA HDD, I'd take it out of the enclosure and connect it
to a SATA port inside the computer (along with power from there). Then
I'd set power options to spin down the drive (for the shortest interval)
and check in Device Manager that it was enabled for power savings. That
way the drive will spin down and you could test that it does spin up
okay. That is, rather than relying on a full power boot of the drive,
have it go into sleep mode and then check it spins up okay when
accessed. I'd want to test the drive itself using its native hardware
protocol works okay to come out of sleep or hibernation before I stick
the PCB (printed circuit board) in the enclosure that converts from SATA
to USB hardware protocols.

"Green" drives are those that use their own code in their own firmware
in their own PCB ROMs to decide when to put the drive to sleep (low
power mode). They do not rely on any power option settings in the OS.
They sometimes have a problem or take too long to spin back up and the
delay can cause software to think the green drive is unresponsive.
However, if after you get the drive working and you thereafter have no
problems accessing the drive (without it ever going to sleep or
hibernate, that is) then green mode is not the problem. I've had green
drives (not sleeping) that decided to sleep during a long period when a
backup program was compressing which then had the backup program figure
the drive became inaccessible and would hang or fail the backup. I want
a drive that stays awake until the OS (not the drive's firmware) tells
it to sleep.

Whose external enclosure do you use? I stay away from Rosewill stuff
because I've found in several different types of products but all using
USB that Rosewill just is not reliable with USB devices.
