Hello.

I have an old 300GB hard drive from the old white iBook G4 lap top.

I used it as an external drive.

 

When i Get Info on this drive from my Power Mac G5 quad, it reads: capacity 232.76GB, available 39.15GB, used 193.61GB

When i Get Info on this drive from my Mac Air....................it reads: capacity 249.93GB, available 42.04GB, used 207.89GB

 

That is a bit confusing, though i don't see it as too much of an issue.

 

My issue it that there are only 3 folders on this hard drive which total about 30GB only.

(One computer (G5) says that the 3 folders add up to a total of 31.79GB, and the other computer (Mac Air) says that the 3 folders add up to a total of 29.65GB)

 

Now, regardless of this discrepancy (which i do want to find out why), I should still have at least 198GB available on this HD.

 

So, i launched Omni Disk Sweeper, and it says that 193.6GB are used on this HD (on the "Drive List" window before I do the actual sweep), and after I sweep this drive, it says that only 27.7GB are used on this drive, and it shows the breakdown of the 3 folders on this drive.

 

I'm just wondering how I'm using 193GB on this drive.

 

Any thoughts?

 

Thank you!!!
