Default Error code 47 (USB hd)

When I use the tray icon to remove the external USB hd, the hd is
correctly removed, but XP SP3 still sees the hd and I have no access to
the hd (I need to reboot the OS).
In device manager I see: "Windows cannot use this hardware device
because it has been prepared for "safe removal", but it has not been
removed from the computer. (Code 47)".

I tried to uninstall the driver, but it doesn't work.

How to fix the problem?

Thanks
Cristiano

http://technet.microsoft.com/en-us/l...(v=ws.10).aspx

Well, you can't access the drive if you have successfully clicked to
remove it. Did you physically unplug the drive from the computer after
removing it via the tray icon?

Are you saying that you physically remove the drive but it still appears
in the Safely Remove Hardware dialog, and if you insert the drive again
it is not recognized until you reboot?

If that's the case, try this:
Reboot the computer, then plug in the USB hard drive so it is
recognized.
While the drive is recognized, go to Device Manager, select the drive
under Disk Drives, and click the Uninstall button on the toolbar of
Device Manager.
After it is uninstalled, unplug the drive, then reboot.
Plug the drive in again after Windows restarts, let it be detected and
installed.
Now see if the problem still exists.

Makes no sense. If you have elected to remove the HD why are you
surprised that your machine can not read it.

Try right clicking on the drive's icon and opt for "eject"

If I safely remove the drive, it no longer appear in the Safely Remove

If I insert the drive again it is not recognized until reboot and when I
try to reboot, the PC hangs and I need to press the reset button on the

Device Manager hangs and I need to terminate it; I can't uninstall the
drive.

You do NOT uninstall Drivers when you want to remove an external read/write
storage device !

When you click on the "safely remove..." function it makes sure that all
caches are flushed and data is written to the external read/write storage
device such that one can "safely" remove the device (read disconnect device)
from the computer. The safety factor is the loss of data that was in a
cache that had not yet been written to media.

But what you do NOT do is uninstall Drivers when you want to remove an
external read/write storage device.

There is no "remove" action in the Safely Remove Hardware wizard. There
is a "Stop" action. You stop the device and then later can decide if
and when you want to physically remove it.

http://fixexe.com/pictures/safely-remove-hardware.png

The device may not be physically detected later until you physically
unplug and replug the device. Leaving it in the USB port after stopping
it may not permit you to simply restart the device. You unplug the
device and then later replug it to redetect it. I've heard but not
tested that some 3rd party software overcomes that limitation so you can
stop the device, leave it plugged in, and restart it later while still
plugged in; e.g., USB Safely Remove (http://safelyremove.com/, $20) and
Zentimo Storage Manager (http://zentimo.com/, $20). Another trick I've
been told about is to use Device Manager to disable the USB hub on which
the still-plugged-in device is connected and then reenable the USB hub
to force redetection of the still-connected devices on it (although you
might have to reenable those still-connected devices after reenabling
their USB hub). Of course, disabling the USB hub means all devices
still connected to it are also going to be affected.

After you unplug a USB device, it may not necessarily disappear from
Windows Explorer until you refresh Windows Explorer. You didn't mention
if you had Windows Explorer loaded at the time you stopped AND unplugged
the device. You didn't mention if you closed the still-open Windows
Explorer to reload it and have it scan for devices again. Close Windows
Explorer, stop the device, unplug the device, and then load Windows
Explorer.

After stopping the device and after physically removing it, can you plug
it in again to get it redetected and usable?

After stopping the device and after physically removing it from the USB
port, have you tried plugging the USB device into a different USB port?
Has this USB device been plugged into every available USB port in the
past? If so and the device is not detected upon reinsertion then it
could be an enumeration (registry) problem. If that's the problem then
registry editing to delete the old ENUM entries can force redetection of
the device but using Nirsoft's USBDevView is probably safer; however, if
enumeration is the problem then usually even after a reboot the ENUM
data is still going to be the same as before and still cause detection
problems (and you noted that a reboot got the device detected okay).

Note that some USB devices are poorly designed. They don't properly
transmit their presentation data on initiation (the USB handshaking)
when plugged in but previously powered up and used before. That is,
they were powered up, used before, stopped (and unplugged) but left
powered up, and upon initiation (plugging in) they don't present
presentation data the OS can understand. I've had that problem with
some MagicJack USB dongles where Nirsoft's USBDevView or Microsoft's USB
Device View show the OS couldn't understand the device's presentation
data (what it sends to the OS to identify its device type). The device
requires a reset on its hardware. Alas, few USB devices comes with a
reset and instead rely on a power cycle (power off, power on) on
themself or on their interface to do a reset.

Presumablly when you use the Stop action (there's no Remove action) in
the Safely Remove wizard, and because you're asking about a device that
has buffers (cache), they should get flushed before the device is
actually in stopped status and BEFORE it get physically removed. I've
read where other users had slow or stubborn USB hard disks (more likely
a poor USB interface in the external case rather than with the drive
itself) after trying to stop them so they used SysInternal's 'sync'
utility to flush the hard disk's cache (force an immediate write from
cache to platters). 'sync' has both flush and eject functions, so you
could stop the device using the Safely Remove wizard, use 'sync' to
flush the drive's cache, and use 'sync' to eject the device (change its
logical connection status) or use Windows Explorer for that.

SysInternals 'sync'
http://technet.microsoft.com/en-us/s.../bb897438.aspx

Even if you stop a device, processes may still be loaded that have open
file handles on files on that device which can prevent flushing.
Zentimo and USB Safely Remove have a Forced Stop function to unload any
apps launched from the drive or unlock the inuse files. SysInternals'
'sync' (freeware) might also work for that but I haven't tested it since
I always close any apps ran from the device or close those files since
I'm obviously trying to yank away the storage device for them.

See http://safelyremove.com/fullFeaturesList.htm in the "Stopping via
disabling". This is were stopping the device in the Safely Remove
wizard doesn't really stop the device (the driver for the device doesn't
perform the requested action) and instead you have to disable the device
in Device Manager. Because the device gets disabled to properly "stop"
it, replugging it in won't get it automatically enabled (so it goes
through its handshaking to transmit its presentation data to identify it
to the OS) - unless you use 3rd party software to automatically reenable
the device upon reconnection.

USB has been somewhat a crappy interface specification not so much due
to its definition (after v2.1) but mostly due to poor implementation in
the hardware. You might find better management of USB devices by using
the 3rd party programs. While SysInternals has freeware, they don't
provide all the functionality of the payware tools. At one time,
Zentimo was more expensive than USB Safely Remove. It had a few more
features but not critical so I used to recommend USB Safely Remove as a
3rd party solution; however, Zentimo lowered their pricing so it's the
same as USB Safely Remove. Here's a comparison between those two
products:

Then disconnect it from the system. It is _that_ simple.

Unfortunately, I have the Italian locale and I don't know the exact

No, I need to reboot.

Yes; always the same result.

It worked well until yesterday, so I guess the hd is good and I guess
that some strange software problems happened.

Thank you, but I think that it is just a software problem.
I connected the hd in my notebook and it worked well; I can connect and
disconnect it without any problem.

If trying the procedure in Safe Mode does not work, download
DriveCleanup v.0.8.1 from he
http://www.uwe-sieber.de/drivetools_e.html#drivecleanup

Unzip it into its associated folders, then run the 32-bit version. It
is a command line tool, you must run it from a command prompt.

Well, you can't access the drive if you have successfully clicked
to
remove it. Did you physically unplug the drive from the computer

after
removing it via the tray icon?

No.
The problem is that after I have successfully clicked to remove the
driver I still see it in the system (for example in Windows Explorer),
but I cannot access it (I got an error message).

Are you saying that you physically remove the drive but it still
appears
in the Safely Remove Hardware dialog, and if you insert the drive

again
it is not recognized until you reboot?

If I safely remove the drive, it no longer appear in the Safely Remove
Hardware dialog, but it still appear in Windows Explorer.
If I insert the drive again it is not recognized until reboot and when
I try to reboot, the PC hangs and I need to press the reset button on
the PC case.

If that's the case, try this:
Reboot the computer, then plug in the USB hard drive so it is
recognized.
While the drive is recognized, go to Device Manager, select the
drive
under Disk Drives, and click the Uninstall button on the toolbar of
Device Manager.

Device Manager hangs and I need to terminate it; I can't uninstall the
drive.

Stop the drive, using the Safely Remove Hardware tray icon.
Then physically unplug the drive from the computer.
REBOOT the computer.
When Windows is loaded, plug the drive in again, so it is detected and
you can access it.
Open Device Manager and uninstall the drive, then remove the drive
physically AFTER that.

Are you saying that you can't open Device Manager even after you have
rebooted and inserted the drive and can access it?


I can open Device Manager, but when I click the menu item to uninstall
the drive, Device Manager hangs and the only thing I can do is to
terminate Device Manager.
I also tried NirSoft's USBDeview and the same thing happens.


If trying the procedure in Safe Mode does not work,


In safe mode I can uninstall the drive, but the problem still persist.

download DriveCleanup v.0.8.1 from he
http://www.uwe-sieber.de/drivetools_e.html#drivecleanup

Unzip it into its associated folders, then run the 32-bit version. It
is a command line tool, you must run it from a command prompt.


It deleted 57 registry keys, but the problem still persist.

I'm starting to think that it is a network problem. I could be wrong,
but when I safely remove the drive, I still see it in Windows Explorer
(as I told you, but not in Disk Management).
When I double click the drive icon, I get the error in the "SYMPTOMS"
paragraph:

"E:\ refers to...".

No.... that doesn't indicate you have a network problem. You have
stopped the drive via the Safely Remove tray icon. Although it is
visible in Explorer, it is no longer mounted and so you get the error.

The only way it would be a "network problem" is if you have, for some
strange reason, mapped the USB drive as a network drive... I can't
imagine a reason why you would have done that, though.
