Well to see block size of file system use:

Hi,
it's HP-UX 11.32.
The command it's ok! 8kb block size
version: 5
f_bsize: 8192

one more:

can you tell me the reason because a dd between two Fs file it's more quick than one with Raw devices? For buffer cache probally?
But if it's the first time, the buffer it's not involved .. or not???

Thank you
Best regards
Francesco
