Hi all,
I'm trying to get my sht straightened out after some data loss, and have encountered something strange. My boot drive is a 1TB HDD, backed up daily to another 1TB external HDD. The drive was corrupted last night during my update to 10.6.4, and so I'm working to restore my data.
According to finder, the primary drive is listed as 840.9GB used, while the backup is listed as 698.96GB used. But OmniDiskSweeper is telling me that the drives are nearly identical at 649.7GB and 649.5GB used.
So where is that 200GB that's missing between the reported amounts of 840GB and 650GB?
I'm beginning to suspect it's a question of formatting. I know OSX recently switched to a new data reporting system, whereby a 1TB drive literally equals 1TB, not a smaller amount. So is OmniDiskSweeper still on the older system? And if so why aren't both hard drives showing an identical discrepancy?
it is very important that I understand this issue before proceeding- the primary drive clearly needs formatting to return it to its functioning state, but I can't format until I'm 100% positive that the mysterious 200GB isn't actual data.
Any ideas?
EDIT: looked at the Get Info screens again, and the primary drive is formatted as Mac OS Extended, while the backup is formatted as Mac OS Extended (Journaled). Possibly a factor?
EDIT2: Disk Inventory X is reporting similar used volumes of 651.0GB and 650.8GB for the primary and backup drives, respectively.
