Corrupt catalogue

[yevgeny2512]

Something happened overnight (due to an update maybe, I am not sure) but when I came back to the mac in the morning, I had to restart it as there was a message saying that there was not enough RAM or something similar.

After restarting, I cannot seem to be able to open the Lightroom catalogue anymore. it says it is corrupted and repairing it didn't fix (message says "LR encountered problems reading or writing from disk when attempting to repair catalogue").

The Mail also doesn't seem to work (it's asking me to rebuild every mailbox which will take 40 hours). I am not sure what happened but I really need to try and fix this catalogue. The last backup was unfortunately 3 months ago (yes, I should backup more often...I forgot). I saw some solutions using SQL but I am not as computer savvy enough to do the commands properly. Is there not a dumbed down version anywhere on how to do this?

I also can't seem to find anyone from Adobe to help (is there a chat function?).

Any pointers would be appreciated. The catalogue is almost 9GB. I don't want to lose the edits over the last 3 months.

Thanks

This would suggest that your hard drive is starting to go bad. The first thing I would do is use the OS tools to scan the hard drive for bad sectors.

I will do this as soon as I finish the backup.

I have also managed to contact Adobe support and sending them the damaged catalog file in case it can be fixed. 

The catalog file only contains data? (there are no images or previews, correct?). I read somewhere that the file contains cached or rendered images but I wasn't sure.

I have personal family photos and don't wish it to be shared obviously.
