Any way to repair Unreadable data files: idcounts.dat ?

Closed this issue · 16 comments

Describe the bug
A world that I can load into once, save, and exit, cannot be loaded again (freezes on "Reading World Data"). When I run Region Fixer the only error I get is:

Unreadable data files:
idcounts.dat

Is it possible to fix this? I don't care of maps are deleted, and I can actually do things in-game, save and exit if that's helpful towards any solution. It's when I try to reload the save that it hangs up on "Reading World Data".

Hello!

That is very strange indeed. You could try to remove idcounts.dat and all the maps.

Answering your question, it might be possible to fix idcounts.dat but regionfixer is not going to do that in the foreseeable future. So the best thing to try is to remove idcounts.dat and remove every map_<numbre>.dat file in the data directory. This could work.

Please, try that and report back if that works.

SkilledAlpaca commented

Interestingly enough I also had the same issue with a corrupted idcounts.dat. Attempting the fix you proposed to delete the idcounts.dat and map_<number>.dat files didn't resolve the issue I'm having though but it was worth a shot. I've placed my console output below as well in-case it somehow helps.

@SkilledAlpaca, so, after removing all those data files and getting a clean scan by regionfixer, the worls still doesn't load in minecraft? That's very strange.

I can say that I'm completely lost. Have you tried to load/create another world? Could you upload the world to test it myself? I'm going to be very busy the next weeks but if I get a moment I will give a look.

Fenixin commented

You could also try the branch bugfix, just in case.

SkilledAlpaca commented

My apologies, my world has always worked and has no issues loading. I'm dealing with a strange problem where when my server shuts down, it just hangs until I manually kill it. One of my troubleshooting steps was to check and see if the issue was caused by invalid or corrupted chunks using your utility. The only error I got was for the idcounts.dat being unreadable.

Fenixin commented

@SkilledAlpaca, no idea what's going on. To me it sounds like a problem with the hard drive or OS, but again, no idea. I hope you can find a solution.

Hi have the same error, but my server kick people and the dedicated server freezes

Fenixin commented

@xxBoWiExx, if you want some help, plase, give some more information.

Here's a link to my world
https://drive.google.com/file/d/1dFM-KCYUrw0rj04ExK-eVetsf9Exe5vI/view?usp=drivesdk

I tried deleting the all the files giving me issues and that didn't work, then I tried replacing them with files from a working world and that doesn't work either. Thanks for the help! Let me know if there is anything else I can do to provide you with more info

Fenixin commented

@ikew123, sorry, no idea what's going on. Your world is completely fine from region fixer perspective. Could you open a new issue with more detailed information?

Fenixin commented

@ikew123, something strange is going on in your world. You have around 2000 region files but most of them are empty or almost emtpy.

In your first post you said "Same problem here", could you please specify exactly what is your problem with more detail? I mean, this issue has this description:

A world that I can load into once, save, and exit, cannot be loaded again (freezes on "Reading World Data").

But I'm not really sure that is your problem, is it exactly the same problem for you?

Fenixin commented

A lot has changed in the world format so I'm going to close this. Feel free to reopen if the problem still persists.

I have a realm open for me and my friends, we're getting timed out sometimes idk what causes it I got the same read from regionfixer as unreadable idcounts.dat, everything else works fine people say it might be an internet thing but it's been running smooth for a week just before this error started happening. Have you found a fix?

Fenixin commented

Hello!

I'm afraid not. It's theoretically possible to fix this by searching the last map used and writing the ID in the file but it has never been implemented. In part because this is not as important as loosing a region file or a chunk, AFAIK loosing idcounts.dat only affects in game item maps.

You could remove the file and wait for minecraft to regenerate it. As always, backup everything before trying!
