Windows 7: Odd free space inconsistency between drives

Odd free space inconsistency between drives

I've just noticed this so I thought I'd ask, I just completed a backup of my files I do monthly, I have a 2TB external HDD which holds backup copies from an internal 2TB, so they are both the same max size.

I highlighted and checked the size and size on disc of the files I backed up, they came back as exactly the same on both drives as you might expect, but in My Computer it says my internal 2TB has 161gb free, and my 2TB external has 147gb free, but they both have the same files, where is this 14 gigs of space on the external?

I have hidden files set to show, there's none. So I'm a little confused.

How was the backup done?

Backup and restore in windows or another 3rd part program? Or did you just drag and drop your files over?

Just by copying them over, no programs involved. The files say they're the same size so I'm not concerned for my files, just weirded out by the remaining free space difference...

Is the internal formatted as ntfs and the external fat32?

You could try formatting the external drive and recopying the data back over.

Just a random thought, is system protection enabled on the external?

It's NTFS, I don't think it's system protected.. how do I check?

I did a chkdsk out of curiousity, just to read the discs. it says my external has some 2000 odd files more than the drive I was backing up.

I had some small issues getting my drive running because the USB cable was faulty, I used a different one and it was fine, but when I was trying to get it working with the faulty cable it kept disconnecting, and it disconnected while I was deleting some old files, could that have put them in some kind of limbo I can't get to?

I doubt it is system protected as it is an external hard drive. If it was it would be listed under system protection in system properties.

The drive being disconnected like that could cause some weirdness. Like I said, I would format the drive and recopy your data over with a known good cable.

It was just a random thought, if you didn't turn it on, Like andrew, I doubt it is on.

Here's a tutorial though for reference,

@derekimo

I actually do have it on and I also use windows backup as well. What I meant was I do not think you can turn on system protection for external hard drives. At least, I cannot get it to work.

Network Drives show red (low space) even though 250GB free
Hi, We have large volumes connected to users here, but silly Windows thinks that 250GB of 3TB is running out of space! Is there a group policy or registry hack that will allow us to not mark a network drive as having low space? Thanks
