Hi,
Having upgraded to LR4 on Wednesday, I suffered a catalogue corruption today. LR4 couldn't recover the catalogue and I had to revert to a backup I made on Wednesday after uploading 1678 new photos into LR4. Fortunately, I have the XMP write box ticked so I just had to correct a few metadata discrepancies (is there any way to do this other than file by file?) and upload a few files I had exported. So I am now up and running again after about 90 mins chasing around.
Now I am trying to find why it happened! I run LR4.4 on a windows 7 Home PC. The photos were on a local drive (G:). I have a system of cloning my discs to an external hard drive using Folderclone which runs automatically at certain times of the day. I have been using folderclone for ages and on this system for almost exactly a year since I reinstalled Windows 7. Folderclone was running - cloning the G drive - at the time the problem occurred. Both it and LR4 highlighted disc problems. Under LR3 I have run both at the same time but had to cease photo-editing as it was so slow (but obviously safe!).
I have just returned from a long holiday and have applied 13 updates since 10 April, 5 of them on 12 April. See below.
It looks to me like the two programs have tried to access the same information and something has become corrupted as a result. Obviously this shouldn't happen and I would expect Windows to prevent it. However it didn't. The obvious questions are about:
- Windows itself and the recent updates
- LR4.4 as there have been instances of catalogue corruption being reported.
Has anyone else experienced similar problems? I would be grateful for any information in case there is something I can do to prevent it happening (other than set LR4 to back up every 5 mins which I have done). I will be posting this on a Windows forum as well.
Thanks.
