Burning CDs

Burning works properly [in general.]

The burning probably worked.  Almost certainly, the failure is in
the verifying.

Find the Linux kernel IDE maintainer, and shoot him.  Literally.
Then perhaps someone else will fix the kernel bug [on the READ side]
that causes this misery.  It's been there for over TWO YEARS.

ide-scsi work[ed], but the maintainer of the ide driver
just cannot bear the thought of fixing this bug.
Yes, the specification of CD-ROM {media + hardware} allows too
much room to create the problem (end-of-recorded-data cannot
be detected reliably to a precision of one 2KB sector),
but ide-scsi dealt with it, and the current ide driver does not.

Instead of using sha1sum to verify, use
  dd if=/dev/cdrom bs=2k  |  cmp - FC5-test1-i386-discN.iso
and check the return code from cmp only, ignoring any complaints
from dd.
