I keep a personal database using ChessBase – not large, maybe 750 games with my notes – my tournament life. I periodically go back and revisit games, maybe let an engine crank on a position, add some new notes, etc. Not often, but maybe 3 or 4 times, it seems like a game just disappears. When I enter a new tournament, I print the games out (and I periodically back up the database against disaster) so I can recover any game I notice that’s missing, but…
I’m more than willing to admit the possibility of user error. Anybody else notice something like this? Any common mistakes or conditions that might cause this? BTW, I store it on a googleDrive, so the database gets synched over desktop, laptop and tablet.
ChessBase 12 in cbh format, although the problem might have occurred years ago. One missing game was from 2011, the other from 2012. I discovered the problem by accident – I decided to input “stubs” for any half-point byes I had taken, and found these weren’t the only rounds missing.
I’m starting to wonder if the gDrive has something to do with the problem. A couple times the DB got corrupted, but was able to repair itself (with some help). I was able to go to some old backup versions and copy/paste the two missing games.
Most likely “user error” somewhere down the line, but just wondering…
I am having similar issues with my personal DB (CB 13, CBH). I started keeping a local file and periodically update the cloud My Games. I use Google Drive for CBV files. Not exactly elegant.
If by gDrive you mean a removable device like a flash drive, aren’t you always supposed to invoke the Eject command before removing such a device? You can right-click on the desktop icon for the removable device, then select Eject. Of course, that won’t actually physically eject the device, but you’ll probably get a message saying it is now safe to remove.
If you remove a flash drive while it is being written to, of course you’ll end up with corrupted data.
gDrive is googleDrive – you designate a folder to Google and what you put in that folder gets uploaded to the cloud and synced to other computers you specify. So, it’s not quite like a flash drive, but I’d guess there are analogous concerns if, say, the computer crashes while syncing.
