Not Showing External USB Images for Restore

[MARK MOORE]

Clonezilla 2.4.7-8-amd64
WD My Passport External USB 1 TB Drive (holds clonezilla images)
Windows XP - Windows 7

UPDATE:
I took the My Passport to a 3rd computer, and it is now showing up there! Seems like the problem is not with the My Passport USB drive or the images on it.

The 3rd computer is a little newer. However, I have imaged the 2 other computer Models before. The main one I am trying to image is a Lenovo ThinkCentre M72e and has Windows XP installed. This makes me think there's a BIOS setting maybe?

2ND UPDATE:

4th Computer and I'm back to it not working.

Lenovo ThinkCenter M900 - works

Dell Optiplex 780 - not working (used to work for this model)
Lenovo ThinkCentre M72e - not working (used to work for this model)
Lenovo ThinkCentre M Series - not working (used to work for this model)

If this is a BIOS setting, I'm not sure what it would be. Something with USB 2 vs 3, but then why does the drive show at all?

---

Originally, I thought this was caused by a failed savedisk to the My Passport, but I can get the drive and images to show on a Lenovo ThinkCenter M900, but not on several older computers.

When I attempt to perform a restore from My Passport, Clonezilla is not showing any of the images on that USB.

It does recognize the drive under "Preparing the mount point /home/partimag" and "Available disk(s) on this machine...",

I press Ctrl+C,

but it doesn't show on the next screen "Now we need to mount a device as /home/partimag..." to be selected for restore. Only the internal drive is displayed.

The USB drive has 19 Image folders on it that we've used for years.

Is there a config file, or format, or something that got changed on the USB? How can I fix this? I need to get several computers reimaged.

I took screenshots to help

Thank you very much!

I copied one of the image folders to a different USB (that is also 3.0) and it works on the computers. Something happened with that failed save disk that did something with the original USB drive. I'm gonna try formatting that drive to see if that gets it working.

Formatting the drive, and then copying the same image folders back worked.

It is definitely not good idea to keep all your system backups in one single hard disk. It is like "storing all your eggs in single basket". If that HDD fails, all your backups may be gone forever. Personally I do not store backups on HDD disks at all. I buy 16GB or 32GB USB flash drives and store 1-3 backups on each flash drive.
P.S. WD My Passport is definitely not the best portable hard drive. I prefer Transcend StoreJet 25M3.
