While upgrading a MDD G4 to Leopard and backing up beforehand, I noticed the creation dates on the root level of the drive had been corrupted/changed to April 5, 1976. These folders were affected: Macintosh HD, /Applications, /Library, /Users, etc. (but not /Users/username folder, which has a valid date, as do most enclosed folders) Also, Tiger would not correctly update the last opened on: field in Get Info, so I decided to upgrade to Leopard and hope for the best. While trying to fix this before upgrading I: Ran Disk Utility Repaired Permissions Ran Disk Warrior 4.2 Flashed the PRAM Changed the 3.6V battery (it wasnt bad) Reset the PMU Sacrificed a few small animals and ran FSCK in single-user mode To backup, I CCCd the drive to an external and it of course now reads the 1976 creation date on that drive as well (awesome!). After upgrading to Leopard (Archive and Install), and then 10.5.8, the machine runs fine. But the creation dates remain at April 5, 1976. However, Leopard did fix the issue of last opened on. I understand that these dates get corrupted due to power outages and bad batteries. (This machine has been left unplugged for long periods of time, frequently >3 weeks) The QUESTIONS: If Im stuck with these dates, does it matter at all? Is there no way to *repair* the creation dates back to the correct dates once they are corrupted? (I feel like this used to be fixable.) Should I bother fixing them manually in the Terminal via the touch command? (Do I just pick a date closer to what it *should* be?) Should I format and start over? Any advice or tales of similar experiences would be appreciated. Thanks in advance.
