[Bug 80258] Re: "copy disk" blocks at end

[Vincenzo Ciancia]

I just discovered that the process is completed after some time, getting
errors on the last sector. I can remember similar problems using dd one
year ago, but don't know what is the cause - maybe block size in read().
The log is self-explanatory. Thank you for your prompt support.
