Specs: windows 10 , Intel I5/16 rams
Copy and paste data from my original 3 gb HDD to an external 3 gb HDD, both properties shows the backup is larger then the original, but If I open both HDD, highlights all the files , hit properties, the amounts of gb stored are exactly the same, Beside both don’t have partitions.
I just run out of options here, any suggestion?

Are you showing all files on both computers? Including hidden and system files?

3GB isn't very much, is there a typo? And how much of a size difference between the two are you talking about?

How can you have 37GB difference if both HDDs are only 3GB? Do you mean 3TB?

"...if both HDDs are only 3GB? Do you mean 3TB?" Probably.
3TB drives are fairly large, how much of the drives are being used? How much space is left?
If you have a lot of room left then you may be worrying for nothing. If you have most of the drives filled then that is a lot of data and a 'small' difference is negligible. You may be going OCD for nothing here.
If the external hard drive is a 'back up' type of drive then there may be built in software for back up and recovery on the drive that is not immediately visible to you. This is especially probably if you are comparing the remaining space left on these drives to each other.
If the drives are not the same brand and type then the 3TB is simply a nominal capacity and the actual capacity will be different and that will vary between brands and even models and may have 'spare' sectors reserved on the drives.

You have to be a little bit crazy to keep you from going insane.

Sorry, my bad , they are 3 tb , one property read 2.17 tb used and the backup read 2.54 tb, so the difference is around 370 gb and as I said , folders and files and size are identical

If the folders, files, and sizes are identical, where are you seeing the discrepancy? Perhaps you could post a screen shot.

Doing the best I can here... And remember, there's always more than one path to success. :)

Did you format the destination drive before copying the data to it?

Yes, if it is formatted, no partitions, showing hidden files,copy and paste same folders, files and size, than why the HDD property shows more space used than the original ?
Could it be the clusters size? Are an cluster size standard on all brands?

You can use a partition software to re-partition it to make the original larger than the backup

Without any details, it's hard to make any judgments of any worth. Narrow down the discrepancy a little. What is larger on the backup, when compared to the original?

It is larger only in the HDD’s properties count, not in the folders, files, size count

Are both hard drives formatted with an NTFS partition? If one is formatted with FAT 32 or other, then the the cluster size will be different and is probably what is causing the discrepancy.

Where exactly is the discrepancy? Are you going into Explorer and right-clicking, then selecting Properties and then repeating for the backup drive?

Are you able to see all files, including ini files, .sys files, etc on both drives?

Why not post a screen shot to show us what you're seeing.

Are you right-clicking on the drive letter and going to Properties? Or are you highlighting all folders/files and then looking at the properties?

What is the file and folder count for each?

Maybe you could post a screen shot

Well, somehow, it didn’ Let me paste the screen shot, so I just typed the properties results, as you see the both HDDs folder/file’s count are similar, the discrepancy come at the HDD used space,

You will not be able to post a screen shot here. I should have been more clear. There are websites that will allow you to upload a screen shot. Just Google. :)

Well, if you're open to third party software, download and install WinDirStat (https://www.fosshub.com/WinDirStat....). Run it as administrator, and compare both drives.
