First of all, I have been a very happy Calibre user for many years. To say I love it is an understatement. If my wife would let me, I would marry this software.

Nest I am using Ubuntu 21.04 and I have upgraded to the latest version of Calibre.

Now the problem. On Saturday, I lost most access to Calibre and all of my library with a database problem. I read through these forums and took the advice and opened a new library and everything went back to normal. Great!

However my old library is very large and is not something I would choose to lose, so I went back and looked at it with other software. Every book I sampled, opened without the slightest problem. so I test transferred a few to the new library and they do not appear in the lists. To me this seems to indicate I have some, hopefully minor, corruption problems. That is the problem I have. I also tried to move them back in as a book file from the Calibre GUI and it was having none of that either.

I am thinking all I need do is go into safe mode and use "fsck" to check all of the files and then go back to that library, then I hear people saying that this method could ruin the entire file. I really do not see how, myself, but it is what I do not know that gets me every time.

So my question is this. Given that I am using the latest Ubuntu and the latest Calibre, what is the best way of repairing the corrupted file, assuming that it can be repaired.

I do know this is a very easy question and one that will be glaringly obvious, but I can only think if I am not certain and it is not answered here, then maybe it should be to save time later.

More like it has been answered many times and I am just blind or stupid.

Thanks
