Time Machine Error Logs

Hi, I have a MacBook Pro Core 2 Duo running 10.5 fully updated. Using a LaCie 500GB Mini Rugged USB external drive as a Time Machine backup drive. I see all these errors in system.log in Console:



Jan 13 07:32:59 Macintosh-2 /System/Library/CoreServices/backupd[186]: Backup requested by user

Jan 13 08:18:21 Macintosh-2 /System/Library/CoreServices/backupd[154]: Backup failed with error: 2


I have done the following:

  • Trashed all Time Machine preference (plist) files
  • Complete format of Lacie drive, journaled HFS, the typical stuff
  • Ran disk permission repair for laptop and Lacie
  • Ran disk repair for Lacie
  • Ran disk verify for laptop
  • Ran Seagate Seatools for Lacie to test the drive
  • Changed power savings to none. Never sleep computer, display and drive. Laptop is always running.


Is there anything else I can try? Thanks!

Apparently the cookie is a hidden file which Time Machine places at the root level of the backup disk.
Its name is your "MAC" hardware address (en0) with a leading dot [period] in the name to hide it.


The poster in that Discussions thread claims that file on his backup disk had wrong permissions.
I just checked, and mine is set to root:wheel & read-only...
ls -l@eO /Volumes/*/.0*
-r-------- 1 root wheel - 16 Dec 31 2007 /Volumes/myTMbackupVolume/.0a1b2c3d4e5f
Run that blue command and let's see what you get.

Discovered the fix. Posting it here in case someone else landed here via Google.


I have the Lacie external drive and apparently they recognized a bug with their Lacie drives + Time Machine. They have a firmware upgrade. This solved the problem.


So in other words, the drive works perfectly fine for everything else, even a hard drive test won't detect anything. The problem is SO specific to Lacie + Time Machine. I am blown away.
