Is there any way to default the 'verify' in the
Macrium7 free home edition menus?

Yesterday, I did an overnight backup of my 64-bit W7 C to prepare for
tomorrow's MS updates. After doing the long back up, I woke up to see
that it failed verifications it just made. Wow. So, I had redo the back
up and then it worked. I have no idea what happened there. I didn't exit
or reboot back into the bootable burned CD.

When I had this happen, it was bad RAM.

Verification is not fancy enough to detect all hardware
flaws, but sometimes you get lucky. I would
take a look at your kit, and try and figure out
why this happened. It could be important!

You should test the memory on your computer, about
once a year. For RAM that "likes to fail", I find
the failures happen around 1.5 to 2 years, so a 1 year
test interval would be good enough here. YMMV.

It could also be drive related, and you could
use the Seagate test on both the source and destination
drives and see if they're OK (assuming both are
Seagate brand say).

The CRC on the cable, has limited detection power. It
may not result in retransmission of errored data packets
over the SATA cable, in every case. But if that was
happening, the error counter for the cable would
be "spinning in the breeze" for all the packets
that did register CRC cable errors properly. The
error count is never cleared, and to detect future
trouble, you record the current value today, and
in the future, compare the number then to the number
now. One of the entries in the SMART table covers
the SATA cable (apparently). No idea how errors
on both ends are logged (the drive can only log
packets coming into it).
