I got basically 2 responses from non-amiga people (via e-mail).
1. The first one says, that on his system (i386), it's actually the
other way around, which means that he gets problems when the
'verify after write' feature is disabled.
2. The second one says that he's using this feature on a JAZ without
the slightest problems.
Hence, the problem seems to be with the Amiga. Either it's the kernel
which slightly deviates in some respect, or it's the host itself
(WD-08) which is behaving differently as expected by the kernel.
Is this now a kernel problem or not and where should I report it?
