Accidentally truncated crontab

[Daniela]

Hi all!

I just emptied the system crontab, and don't know how I can recover it.
I know that the contents are still somewhere on the drive, as I didn't write 
anything on that partition.
The size of the file must be stored somewhere in the inode, or maybe in the 
directory, so I could just load the raw partition into my hexeditor and 
change that field to the original length. But I thought I'd better not touch 
it without consulting the experts first, because I don't have much experience 
with file systems.
In the ports I couldn't find an undelete utility, and the -w option to rm 
doesn't work here.

Please help me, or at least tell me that there's nothing else I can do, so I 
can use the method mentioned above.

Regards,
Daniela
