First, quit Disk Utility.

In your Terminal
open ~/Library/Preferences/com.apple.DiskUtility.plist
OR in your Finder, open your Home folder > Library > Preferences > doubleclick on com.apple.DiskUtility.plist

In either case, if you have Property List Editor installed, it should open in that app.

Now, with your Disk Utility prefs file open in Property List Editor, look for a property named exactly DUDebugMenuEnabled. If it doesn't exist, click on the top line, where it says "Root", and click the "New Child" button. It will open up a new Property, type exactly, precisely (and case counts, so get it exactly right):
DUDebugMenuEnabled
Set the Class of DUDebugMenuEnabled to "Number".

Set the Number of DUDebugMenuEnabled to 1.

In Property List Editor, go to the File menu and click Save. Quit Property List Editor. Launch Disk Utility and see if the Debug menu is present.

I'm sure that there's a one-step command in the Terminal that would do all of that too, a defaults write something something something, but I'll leave that for someone else to say.

Found the problem - not the solution...
- show all partitions -
1 hidden disk.
can't mount
can't disk aid
can't erase...

I have already
repartitionned the ATA disk
secure erase...

How do I remove that unmounted disk
any ideas?

thank you

I'm not sure that you need to. Can you show us exactly what you're seeing?

There's always partitions (quite small) that are created as part of the volume scheme that you have. One example is the partition where the drivers are installed. Those tiny partitions are not for your use.
For example - I have 2 partitions, with 8 hidden partitions, which is completely normal.

What do you need to do with your hard drive - what is your goal?

On a GUID formatted hard disk (Intel Mac) there is always a 200MB EFI partition. This is required and speeds the boot proceedure as well as aids Boot Camp.

In the case of an Apple Partition Map, at least one partition (31.5K) holds the partition map itself. If System 9 drivers are install, eight additional partitions are used.

Deleting either of the first partitions of GUID or Apple Partition Map drives will render the drive non-bootable.

It has to be run under normal user and not root user
