[TriLUG] cpio checksum errors

[Paul Boyle via TriLUG]

Hi,

I bought myself a new x86_64 laptop and installed OpenSUSE LEAP 42.2 on
it.  I used cpio (using the crc format) to archive my /home directory
from my old computer writing the archive to an external hard drive.  I
then took the external hard drive plugged it into the new computer
copied the archive file (approximately 23 GiB) to the new /home
directory and unpacked it.

Out of about 70,000 files, I got 107 checksum errors. Typically it
looked like this (sorry for the line wrap):

cpio: boyle/Pictures/2008-08-02/2088-08-24/MVI_0075.AVI: checksum error
(0x1ce87d5a6, should be 0xce87d5a6)
cpio: boyle/Pictures/2008-08-02/2088-08-24/MVI_0034.AVI: checksum error
(0x1337929d6, should be 0x337929d6)
cpio: boyle/Pictures/2008-08-02/2088-08-24/MVI_0032.AVI: checksum error
(0x1c23725ea, should be 0xc23725ea)

I  haven't checked all of the files.  There were some PDFs which gave
errors and those opened in okular OK and I didn't notice any gross
errors.

I am concerned about these errors, but I don't know if they have any
real effect.  What is other people's experience and how should I
try to deal with this?

Thanks for any suggestions.

Paul
