[FWTools] Fail to use FWTools - ogr2ogr to convert S57 to CSV

Dear Sir/Madam,

I am new to this topic but I receive a task to handle S57 files.
I have a S57 files (*.000) and I can view it by SeeMyDEnc.
I use the following command to convert it into .csv files:
 ogr2ogr -f "CSV" S57-CSV C24VTC41.000
The process is successed with some warning messages. Then a series of .csv
files are generated in the folder "S57-Test". After that I would like to
revert the process and convert those .csv files into a single S57 file by
the following command:
 ogr2ogr -skipfailures -append -f "S57" S57test.000 S57-CSV
The process finished with the following error message:
 Layer DSID not found, and CreateLayer not supported by driver.
The generated S57 file is smaller than the original S57 file and I fail to
use SeeMyDEnc to view it (a blank page is opened without any errors).

Did I do something wrong? Is it the limitation of ogr2ogr utility? Thanks in
Best regards,
