You only get that error if a) the first four bytes of the file are not
'FS21', or b) the file is smaller than 4 bytes. Are you sure you were
trying this on the corrupted Data.fs? If so, you may have a bigger
problem on your hands.

The exception included the position: 10020462. I just advised you to

Take a look at what fsdump.py does, it uses a FileIterator to list all
transactions in the Data.fs. The returned objects (RecordIterators)
represent the transactions and you can iterate over these to pull out
all data associated with the transaction. Each transaction id is based
on the timestamp (use ZODB.TimeStamp.TimeStamp to decode it) so it
should be but a small job to extract everything between two given
See the sourcecode for fsdump.py and FileStorage.py in ZODB/FileStorage.
