thestevew Posted January 27, 2008 Report Share Posted January 27, 2008 Retrospect 6.1.126, iMac G5, 10.4.11, LaCie Firewire ext backup volume I've been doing backups to this external Firewire drive for a couple months. It has two backup sets - one an Retrospect Express set for a MacBook and another a Retrospect 6.1.126 set for the iMac. I backed up the MacBook yesterday just fine. Last night I started 6.1 on the iMac to do a recycle backup. It started fine and before I went to bed I noticed it had completed about 75% of the file copies. This morning I woke to an error message - log follows: 1/27/2008 4:05:29 AM: Comparing iMacHD… Device trouble: “iMac Backup Set A”, error 115 (data portion of split file backup set is missing). 1/27/2008 4:05:43 AM: Execution incomplete. Remaining: 867556 files, 180.4 GB Completed: 0 files, zero KB Performance: 514.5 MB/minute (514.8 copy, 0.0 compare) Duration: 05:59:40 (00:00:47 idle/loading/preparing) The catalog is there but the backup set is gone - not invisible - gone. I quit Retrospect, unmounted-restarted-mounted the external disk and it's working fine - I've moved files to it and the other backup set for the MacBook is there. (It's on a 400 GB partition of a 500 GB disk) The file system is still reserving the space though (180 GB). I ran Disk Utility & TT Pro and both "fixed" the directory and report the disk and structure are fine but the file is still gone and the space still reserved. Running any checks in Retrospect fail - it of course doesn't find the backup set.

Anyone have any ideas on what happened to the backup and/or how to recover it? Thanks, Steve Link to comment Share on other sites More sharing options...
CallMeDave Posted January 27, 2008 Report Share Posted January 27, 2008 Sounds as if your hard drive is hosed. If DiskWarrior doesn't give you any more information then TT or DU did, your only other option is probably going to be reformatting the drive. I don't know much about Samsung drives; I'm a Seagate aficionado myself. Link to comment Share on other sites More sharing options...
thestevew Posted January 27, 2008 Author Report Share Posted January 27, 2008 Thanks... The drive *seems* to be working fine. It's only a couple months old and I only use it for backups once a week. I know that doesn't really mean much - but I'm unmounting/mounting/reading and writing files just fine. TT and DU report no problems. DW tried to rebuild and its preview showed basically an identical disk (ie same erroneous used space). I really don't want to reformat unless I have to just because of the time it will take. It seems to me I've read before on solving problems of incorrect disk usage being reported but I can't seem to find anything useful this morning. If I could just get it to free up that space I'd be OK for now. Oh well - I seem to be singlehandedly keeping disk vendors in business lately - maybe this is just my latest installment...

thestevew Posted January 27, 2008 Author Report Share Posted January 27, 2008 Resolved I just discovered the backup file in the trash. I moved it back and Retrospect is doing its compare as I type. My apologies - the used space issue should have pointed me there earlier. Now - if I could just figure out how it got there.... Link to comment Share on other sites More sharing options...
CallMeDave Posted January 27, 2008 Report Share Posted January 27, 2008 A _great_ program for graphically representing disk usage is the open source GrandPerspective. It would have found your moved file in a jiffy! http://grandperspectiv.sourceforge.net Dave Link to comment Share on other sites More sharing options...
