Err, thanks, but I am aware of all that. It is a stream of bytes, it just
happens to be formatted into blocks on the disk, for identification, error
checking and recovery.

If you read back in the thread, you'll see that what i'm really getting at
is that a byte  stream is the most generic / lowest common denominator, from
which all other data formats can be layered on top of.

Since there are possibly an infinite number of data structures that you 
might
want to develop in the future, it doesn't make sense to lock all that down
within the file system itself...

Regards,

Chris
