Yes, if you used LUKS this is exactly what happened. cryptsetup created a new, random master key and wrote it over your old master key. Keeping data by using the same password to create a new mapping only works for plain cryptsetup without any header. With LUKS (and similar schemes like Truecrypt) passwords are completely unrelated to the master key which is used for actual data encryption. > I didn't back up many important files, because my other drive > failed not long time ago and didn't get new one yet due to cash shortage.

Your password unlocks the master key which in turn unlocks the data. But you have overwritten your old master key :-( I hope you will find a header backup or someone else has an idea where the old master key might still be found...
