I have en external HD with some important files. The Drive is
connected via USB. Two days ago the HD stopped appearing in Explorer
when plugged in. Since I cannot see the drive in Explorer I cannot
access the files. The drive does appear with it correct name (HD2Go)
in Controlpanel, System, Devices. If I right click I get the message
(in Danish) that the device is working correct. When I connect the HD
a message appears that drivers are being installed, and then that
drivers are installed and the device is working.

Thank you for any suggestion.
Erik

Ah! Your drive may only understand English :-)

Go to Control Panel - Administrative Tools - Computer Management
- Storage - Disk Management (local)
(Yes, you'll have to guess the translation for all of them :-)
You will probably see your external drive there, but without a
drive letter assigned to it. You can assign a letter here.

If the external drive realy is faulty, keep in mind that it is
often the USB interface electronics in the external exclosure
that is at fault. Often, placing the drive in another enclosure
or directly into a PC renders it readable again.

Hello Glowing Blue and Gerard
Thank you very much for sharing your knowledge. This information has
been useful to me, even the problem is still unresolved.
I tried to connect the faulty drive to 3 different computers, all with
the same result. The drive can be found in system devices, but it
cannot be accessed in Explorer. I went to a computer repair shop; they
told me that it has lost the partition; they are trying to recover the
files; a process I probably could do myself with a program like
GetDataBack or TestDisk
