Consistently, when I try to use dd to create an iso file from a CD, the
iso file becomes much larger than it could possibly be.  I ussually stop
it when it hits a gig.

Everywhere I look online suggests that this should work:

dd if=/dev/cd0c of=/path/image.iso

But it just keeps on writing until it fills the disk.

I have also tried playing with block sizes.  I believe a CD9660 file
system has a block size of 2048 and my ffs file system on OpenBSD is
512k blocks.

So I have tried bs=512 and bs=2048, and I have also tried ibs=2048
obs=512.  No matter what I do, that sucker just keeps on writing.  Using
dd normally always worked in BeOS...  Is there something else I could
try or is this function buggy in OpenBSD?
