Hi, Jerry–
Do you know what sort of matrix these limonites-after-pyrites occur in? Were
they free-standing crystals, or were they packed in solid clay or some such
that might have helped retain the shape?
"Sector not found" that does not repeat for CHKDSK or a disk doctor program to
find and fix makes me itch to rebuild the hard disk starting with a _low_ level
(physical) format – the heads can drift slowly off alignment with the original
formatting, especially if the disk is not in the same attitude as when it was
low-formatted (like when you stand a flat system unit on its side like a
tower).
But I cannot see that causing line noise, so I have to wonder if you have good
enough line filtering and surge suppression.
