that is a pseudo code for device address were the X is the actual device indicator when it is an unknown. example
the actuall addres is gotten by using lsblk or the others, if you are using a dvd/ or usb stick OS, then if lsusb is not installed then it might be able to be installed, only if you have enough room for it on that UBS stick then it will be lost when you turn it off. I say maybe because they are not set up to even do that. install packages onto them. some leave a little room on the USB Stick where one might get away with it though.

Execute the command that you mention and I still can not see the disks, I think it would be convenient to change the distro to clonezilla, however I like the MC option (midnightcomander) that brings the BakAndImgCD know of some distro that meets these options in order to support specific files and make complete images, thank you very much to all for responding, greetings.

Hello, I continued doing tests and I discovered something very strange, I formatted the hard drives as FAT32 and immediately I recognized them the BakAndImgCD so I assumed that the best format would be exFat but when formatting exFAT again I did not recognize the discs which is very strange because I understand that the exFAT format is compatible with linux, and it makes me stranger that it does not recognize NTFS since the internal hard disks of the PC (Operating System and data) are in that format and if they are recognized by the BakAndImgCD , I really like the distro but I think I'll find another one, greetings =(

That assumption was incorrect. exFAT is not a "Linux-friendly" filesystem.
And once again:
.

It sounds as if you may have chosen a distribution that is not appropriate for your intended purpose. Midnight Commander is available for MANY distributions, I might select another.

Clonezilla is very appropriate, IF your purpose involves device recognition and copying. It is not one I would run every day. For your purpose you want one with a reasonably complete driver set and good device recognition. There are many to choose from. I would visit Distrowatch and seek one that has the features I desire, and that is in current support.

That's only partly true. It's not about MC itself , but how this application is used. Some 4MLinux scripts use MC in the way, which you won't find in any other distro.

That's true.

Thanks for answering, you can recommend me some distro for my purpose I require it to make disk images and in some cases backups of some specific files without having to make the complete image of the disk, thanks and regards.

Thanks for answering, I will use the complete verison of 4MLinux to try, in the same way if you know another distro for my purpose I will thank you for recommending me some, greetings.
