Hello, the dicrepency between the to is due to apple switching to 1K = 1,000 Bytes instead of the old 1K = 1,024 Bytes... as I recall they changed it in 10.6.x
OK, now the missing GBs.
We either have hidden folders/files on the drive and/or Permissions on them betond your right's.
See WZZZ's post here on how to run ODS in root mode...
Open the Terminal (in /Applications/Utilities). Copy the following line and paste it directly into the Terminal window, then type Return:
Enter your admin password when prompted (it will not echo on the screen), and type Return.
This should open OmniDiskSweeper's "Drive List" window. Click inside it and then sweep your HD as you did before. This time OmniDiskSweeper should run with "root" privileges - see what you get this way.
wow, ok so with root priveledges, ODS has been working for 20 mins, and it is still sizing up a file named ".Trashes".
This file is up to 688 GB large, and still growing.
It appears that Time Machine is the culprit here, causing the ghost GBs.
When i click on this .Trashes file, it shows that within this file, the next level down, is a file titled "505", and within that is a file(or folder? can't tell) called "Backups.backupdb 02-52-33", and within that, "My Name Power Mac G5 (5)", and within that, there are like 20 different backups which are labelled as dates.
Aqua, i don't mind pulling the 3 folders that I actually need off of this drive, saving them elsewhere temporarily, and just reformatting this drive.
Would that be the way to go?
ODS is still sizing up this .Trashes file. It's up to 845 GBs......
Those that are hidden files... have you emptied the Trash on that Drive?
There are terminal instructions here to use Terminal get rid of those files.
Solving Trash Problems...
hmm.... i didn't know that there was a trash on that drive, because i use it as an external drive, and there is no OS on it, so I don't see a trash icon, or a menu that has "Empty Trash" in it.
I will follow this Terminal instruction.
I guess you think that is better than just reformatting, being that i only have 3 relatively small files on this HD...?
