TM Reports Wrong BU disk size?
TM machine has worked fine for over a year, now it keeps failing to do backup, by saying "Backup is too large for volume. Backup requires 307.7 GB but only 78.6 GB are available". This is wrong. The Backup disk has 735.9 GB available. It's the same 1TB backup drive that I have been using for over a year with no problems? I tried disconnecting the BU drive, and deleting the "com.apple.timemachine.plist" file from Library on iMac, then re-connecting and re-selecting the BU drive in TM options, but it does the same thing, with the same error message. When I open TM options, after selecting the BU drive, it says "Available: 735.9 GB of 870.3 GB". I even tried un-checking the "warn when old backups are deleted" in options, but it doesn't make any difference. Any ideas?
