Another indicator poiting to Windows and the harddisc I think.

Why do you think that.
The database (metadata.db) is never very big, I doubt there are many bigger than a 100MB, the biggest I have 18MB for a 30,000+ book library.
To show Windows is not causing your problems: can you take your G: drive, containing calibre portable and your bad library, to a friend or relative and use their computer to do a test. I appreciate the other computer won't have Zoomtext, but perhaps they can help you, or if they have a laptop they could bring it to your place. If you get the same problem on another computer then that would more than convince me that Windows is not the cause of your problem.
As I understand your posts you've done tests of the same library on three drives - C, D and G - and gotten the same error. So, IMO, its most unlikely to be a drive problem. But if you were able to copy the library to a friends computer and do a test and it fails, then that should put the bad disk theory to bed.

Which IMO is further evidence that the problem is almost certainly in the library.
You can copy
most of your installed calibre configuration folder to the ...Calibre Portable\Calibre Settings folder, but I don't know which files and folders are not OK to copy.
Based on everything you've tried (different drives, different computers, different versions of calibre) the symptoms are that the library - probably the metadata.db component - is broken. So recreating your installed calibre configuration in calibre portable is unlikely to change that - my prediction is that it will still crash.
IMO you're going to have to rebuild the library, suggestions have been made on how you could do that. And again IMO, everything else - Windows XP, bad disk drives, Calibre configuration data, Zoomtext, languages etc - are diversions.
