Re: dd on CDROM?



Note that there's a bug in the buffer-cache->cdrom device mapping,
such that reading a non-raw CD device produces garbage.  In paticular,
each 2K block of the CD is repeated four times in the output stream.
The workaround is to use the raw CD device (and a blocksize that is a
multiple of 2K).

I discovered this bug back in 2.7 (or was it 2.8?) but haven't managed
to find time to trace it down yet.
