Clonzilla - back up usb drive not recognized

[ssfc72]

I have been using Clonzilla to image off the Win10 upgrade, for each of my notebook computers.

On my Acer Aspire Core 2 Duo notebook, Clonezilla worked without problem, in creating an image backup of the Win10 upgrade.

However, on my new Dell Inspiron 13, model 7348 notebook, Clonezilla would not find my portable usb backup drive ( a 2 TB Toshiba drive), that I had no problem with for the Acer notebook.

I was using the latest Debian version of Clonezilla (2.4.5 -23)
I then tried the Alternative stable Ubuntu, 20160210 Wily, which was supposed to work with uEFI based notebook computers.  Clonzilla still was unable to find the usb portable backup Toshiba drive.

I then went into the Dell Bios setup menu and besides having the Legacy Boot option turned on I also enabled the Legacy Option ROMs and Boot List Option - Legacy

Clonzilla was then able to find the Toshiba portable usb backup drive. :-)

Thanks for the tip, Bill!

So this implies that certain external HD's have ROMs that make them unreadable on UEFI computers? Bill, you should bring your drive to the next PLUG MUG or monthly meeting so we can test this out on a bunch of other laptops.

I am thinking the problem has something to do with the Win10 upgrade, on the Dell notebook.

I had no problem using Clonezilla and the Toshiba external portable usb drive, to store an image of the original Win7, that was on the Dell Inspiron

Are you sure that the option wasn't Legacy USB drives or something similar? ROMs are usually for booting from network cards over images downloaded over the network.
