That is because the verify phase of k3b will not wait till the drive has 
recognized the disk after the eject cycle, so it errors out.  I have squawked 
about that on the k3b bz, to no avail.  I have also replaced an otherwise 
perfectly good dvd writer, no diff.

I just do one of the whole unmounted disk after calculating how many 2048 block 
sectors dd should read from the disk and feed to sha1sum.  Works everytime.

How the kernel reports the timeout error could have a bearing on it I suppose.

I had trouble long before we got to 2.6.25.  The above is my workaround.
