Hard Drive Capacity Confusion
1 Attachment(s)
I have a 3 year old 27" iMac desktop. The hard drive was replaced at an Apple Store due to a recall quite awhile ago. I'm trying to figure out the size of the hard drive they put in. When I go into "About This Mac" the hard drive is listed as 999GB. When I go into Finder, I see Macintosh HD with 999GB Capacity. However, I also see another "Drive" ("disk image" ??) with a listed capacity of 2TB. I don't understand the difference. Is the drive partitioned? How much capacity do I really have? Sorry if this is a basic question, but I'm confused. I think I attached a screenshot to help answer my question.
Thanks in advance.

Looking at the General tab says it is 2TB with just over 594GB available.

I don't see how I could have used 1.4TB of space on this drive. I have Time Machine setup to save backups on an external drive (which is not attached at the moment). Is it possible the guys at the Apple Store originally setup Time Machine to backup on the internal drive and that's what's taking up so much space? If so, how can I check?
I probably don't have more than 300GB of pictures and music stored on this computer. I don't have movies/video stored. Probably 50GB of other files besides the OS and Apps.
If somebody has a quick answer of how to figure out what is taking up so much space, that would be great. Otherwise, it will just remain a mystery or which I can live with.

Time Machine stores local snapshots on the internal hard drive, although I don't think that's what's happening here, About Time Machine local snapshots.

Are you able to eject the drive (disk image)? Can you see the files in it? I noticed it is an encrypted disk image, are you using FileVault?

I am not able to eject the drive.
I can see the files on the drive.
I just checked and FileVault is on.
I also noticed the the "HLH" drive which is 1.4TB is listed under Users in the "Macintosh HD" drive. I'm not sure if that means anything. Screenshot attached.

Ah, more fun with Filevault most likely. Wretched program that nobody apart from CIA field operatives actually needs.

Can you take a screenshot of what Disk Utility reports for your boot drive? That will probably clear things up.

Here's a snapshot of the boot drive.
I'm guessing my drive is only 1TB, but am confused why it states 2TB under the User HLH, and states I've used 1.4TB of the drive. The snapshot of the boot drive looks like correct usage of my system: (1TB drive, 400GB used).
I do appreciate the time you have spent on this issue, but definitely don't want to waste anybody's time since this doesn't seem to effect the performance of my machine. Maybe I should go on being blissfully ignorant. If this needs to be anymore involved, let's just chalk it up to a known unknown, as Rumsfeld might say.
One question: Is it worth shutting off Filevault?
Thanks again

FileVault can be the very pits. Never ever forget the password........
