For years, our extremely large Calibre database (8.7.0), which contains many additional data fields, has been running on an external LaCie hard drive.
Now, our MacBook (14.7.6 Sonoma) crashed while I was working due to a power outage.
Since then, Calibre hasn't been able to open.
Even multiple recovery attempts, as well as restarting the computer and opening Calibre in Safe Mode, did not resolve the problem.

The following is the error message:

calibre, version 8.7.0
Corrupted database: The library database (/Volumes/eBooks_LaCie/Calibre_2023_08_12) appears to be corrupted. Do you want Calibre to attempt to restore it automatically? The restore may not be successful. If you select No, Calibre will create a new, empty library.

apsw.CorruptError: CorruptError: database disk image is malformed


Is there still hope for rescue?
