I have a VirtualBox set up and Unbuntu installed on the VM. The host is Windows 10. Right now I have a few old Mac drives mounted to some USB ports through some dongles (threw out the Macs, boards corrupted) and they are showing up and I am able to browse them in Unbuntu latest (as of this writing November 1, 2021).
I am trying to transfer some .jpg files from the old drives to my more modern MyPassport drive so my Windows machine can view the images from the old iPhotos library on the old Mac drives.
A couple of questions.
Everytime I try to go into some of the folders of the external drive, it prompts me to authenticate each and every time and on every image. Fairly annoying. Would really like not to have to do this. Tried Nautilus, but still ran into permission stuff, so I went back to the user.
I am doing a direct "Copy" (right click > Copy), and copying files to the WD MyPassport so my Windows machine to view the files. The images are just .jpg files.
That said, When I go to the MyPassPort driveI am getting a lock icon, a red 'X' icon AND and 'arrow' icon. Not idea what the X and the arrow icon mean, but figured the lock is Unbuntu wanting me to authenticate to view the file again. But why the X and the arrow.

The issue is when I try to open the image file in Unbuntu from the MyPassport drive, it tosses me another fun error:

My question is:
- What is causing the issue between the transfer from the Mac drive to the MyPassport drive?
- Do I need to copy directly to Unbuntu first then dump it to the MyPassport? (Since it is a VM I didn't allocate that much space to the partition. Mostly just to run Unbuntu)
- Is there a way to transfer the files and get the files to transfer to the MyPassport or am I missing something in this process?
