Iomega external HD not detected by any computer

You evidently have no language barrier plus there is always google translate.

Thanks for the new snip which is excellent and answers a couple of questions.

Let's try doing this with Microsoft software.

1st: go to an "elevated command prompt'.
Go To an Elevated Command Prompt


Elevated command prompt = Run CMD.EXE as administrator
WIN | type CMD.EXE | do not hit Enter |
CTRL+SHIFT+ENTER keycombo| YES

WIN is the key with the Microsoft flag on top.


=================================================

Use DISKPART to prepare your external disk for use

Enter all commands (shown in bold) followed by hitting ENTER.
Be sure to read the comments.

DISKPART (run the DiskPart program)

LIST DISK (this will list your disks)

SELECT DISK 2 (this should be 500gb external iomega)

DETAIL DISK (this info should help you verify that you have selected the iomega)

CLEAN (this will zero any partition table)

CREATE PARTITION PRIMARY (will create one partition for entire drive)

FORMAT FS=NTFS (will format the disk in the New Technology Format System)

ASSIGN (win 7 will assign the next available letter to the partition you created)

EXIT (to exit DiskPart)

EXIT (to exit the command shell)

==============================================

Now you disk management should show the drive as allocated and with DiskManagement you can change the partition letter if desired, shrink the partition and create a new paritition in the space freed up, give the partition a name, etc)

yes, if you are sure that you have selected the correct disk.

Very possibly a problem with either the firmware of the external drive or the controller of the external drive.

I suggest contacting the iomega website.

You might want to use Speccy or SIW to get yourself a little more info about that iomega drive other than being an external drive. I suspect they will be interested in a model number and possibly a serial number.

Yes.
