device (h_ro,enf;0x200): hd0: 512: 16693328: 8546983936: 0+16693328

512 bytes/block  *  16,693,328 blocks = 8,546,983,936 Bytes
8,546,983,936 Bytes = 8,150 MB

Hm. 8GB is a little bit greater than 650 MB.  :-)

I tried different CDs (bought and burned ones): 
The result is always the same.

Is there any way to override the autodetection?

/hurd/storeio hd0

/hurd/storeio --writeable hd0

Although the cdrom-drive is a ReWriteable-Drive I think 
this is not correct. So I tried...
~#fsysopts /dev/hd0 --readonly
... which said: 
fsysopts: /dev/hd0: --readonly: Operation not supported.
