 Street prices are already below that - about time. For personal use all this

 Interesting. I don't understand why the 'mt' is required, where is the data,
written by 'dd', written to? A cache which has to be flushed? Or is that mt
just to end the session?

 Yes, but for that purpose a 'fsck' is not what you want. What you want is
a compare - can be done with normal applications - of the two trees or
a simple checker which tests all the files on the CD-R if they still are
compliant to the Extensions...
