Inaccurate Hard Drive Space Calculation
I recently purchased a 6TB Seagate Backup Plus Drive for my Windows 10 computer. I copied all of the files from my 4TB Seagate Drive (which currently has about 3.5 TB used) to the new drive. Now the new drive shows approximately 5.45 TB used. I checked the "Properties" for each of the folders on the new drive, but the total space used is the same 3.5 TB on the smaller drive. There is no indication as to where the extra 2TB of storage is being used. Please advise.
Thanks,
Phil

maybe the computer cannot address > 4 tb?
How much memory does it have?
What OS are you using? what bit-ness?

Attached is the Screen Shot of what Disk Management shows. It appears that everything's in order.

I'm not sure exactly what Crystal's asking, but here are my computer's system stats:
perhaps partition the drive into 2 or more logical drives that are smaller? So maybe the address of a file would not be bigger than what the OS can address?
perhaps the unused space is in non-addressable areas ...

Nothing wrong with the machine statistics. Try the drive space tools.
Please see my article on using tools to find out what's using space:

Also, check the allocation unit size. If the old drive used 4K clusters and the new drive uses 64K clusters AND you have a LOT of small files, then you could literally be using 16x more space for the same amount of data.

Well, that solved it. There's a folder called "Seagate Dashboard" (which I just assumed had the usual operating files so I didn't check the folder size). Turns out it has a duplicate of my other hard drive totaling 2.5TB. If you know how to eliminate it - or if I can just delete it - please let me know. If not, I'll try contacting Seagate.
Thanks, John

Thanks for the update and I was pleased to help.

Turns out the new hard drive had a backup program that was duplicating the folders I copied.

Perhaps the BIOS on your machine cannot see such a large drive.
