Hmmm. Until I read your last comment Paul, I was thinking it sounded
rather like the symptoms I had ... which were resolved by a new PSU.
In my case also the symptoms were alleviated by RmKill DMAManager - I
believe because it slows down the copy process and so does not stress the
disc(s) so much, and hence the PSU has an easier time. Reading discs was
fine, it was writing that caused the problem, particularly large files.
If it helps, I wrote a little program to provoke the disc write problem
to aid my investigation (it usually hit me when Pluto was compressing its
large files, which was a b****y nuisance!). If it would help you, drop me
a line and I will send it.
