hi all:

I need to move a SYSTEM datafile from a filesystem to a raw device. I have shutdown the database, copied the file via

dd if=system of=/dev/raw

renamed the file in the database, but couldn't open the database because of the error: Unknown File Header Version read for file number 1.

I tried another dd:

dd if=system of=/dev/raw obs=32768 (32K is the db block size), but I got the same error. Can anyone see what else could be wrong with my dd command

thanks

Gene
