Hello! My Asus netbook running Win7 does not show the external hard
disks formated in NTFS on whom I wanted to create a disk image of the C:
partition. Any backup or simply the copy of files is therefore
impossible. However, the disks are recognized when I activate their
ejection. Could anybody enlighten me on this behavior and help me out of
this trouble? Thank you for your kind answers.

You may have no drive letter assigned to the drives.

click the Start orb and right click Computer (or right click Computer in
any windows Explorer window).

From the drop-down menu choose Manage.

In the left pane of Manage, open Disk Management (it's under Storage) and
wait a few seconds for it to start.

If your drive is there without a letter, right click and choose Assign
Drive Letter and Paths.

Assign a drive letter.

Thank you very much, Gene, for your prompt response. Now it works fine.

Looks like you solved his problem, but I thought USB drives didn't require
you to open Disk Management to assign drive letters. I have three 1.5TB USB
drives that auto assign anytime I remove and re-install them.

You're wrong.

If the drive letters have ever been killed they stay dead.

Glad to have helped.

The voice of experience: it's a pretty mysterious thing to track down the
first time it happens :-)

Come to think of it, it can be pretty confusing even the second or third
time it happens...
 
Killed? What do you mean?

What I said.

Follow the instructions I gave to Antoine Paoli, but instead of assigning a
letter to the drive, click on Remove and say Yes. Now the drive doesn't
have a letter, and it won't ever have a letter when you plug it in to the
same computer, until you follow my original instructions.

BTW, do *not* do this to your boot drive or Windows drive :-)

I didn't mention it before because the last time I looked, I wasn't
presented with that option on C: (my system drive), but I just rechecked,
and this time I had the option (I must need new glasses).

Das ist nicht gut.

Then we'll agree to disagree. Out of the box my USB drives are assigned a
drive letter. Depending on which one I plug in first it will automatically
be assigned a letter. May not be the same due to order in which I plug them
in. What reason would I have to go into DM and remove a drive letter???

Then we'll disagree for one reason only: you are wrong.

Just because you don't know something does not make it false.

You are correct that out of the box USB drives are configured to get a
letter when plugged, which of course agrees with what I have said.

Here are two reasons to take away a drive letter:
1. To hide the recovery partition from a user or from software, so as to
preserve it from accidental access (this is not on a USB drive, of course).

2. To automate a backup program which runs overnight, but can't deal with
drive letters that change depending on when a drive was plugged in.

These are two things that I have done for the reasons given.

I'm back from a trip where I didn't have access to Usenet...

In addition to number 2 above, Windows offers the ability to attach a drive
to an empty folder, i.e., a mount point. That one saved my butt recently
when I tried to use SyncToy on a cell phone. It kept SyncToy in line, and I
didn't even have to kill the drive letters. It probably wouldn't work for
drive backups, since the destination drive would look like a folder on the
source drive, but I guess the mount point could be configured as a folder
to exclude. Dunno.

There is also software available that will assign a USB drive a chosen
letter based on the drive's ID or other characteristics, but I decided not
to use it. http://www.uwe-sieber.de/usbdlm_e.html#download is the only one
that I am aware of.

Thanks for the additional info, Gene.
