[arch-general] smartctl - 199 UDMA_CRC_Error_Count

[Apfelkuchen]

Hey,

I tested my hard drives with smartctl -a. And for 199
UDMA_CRC_Error_Count I get a raw value of 808. Should I worry about this
disk?

I'll post you below the whole output of smartctl -a. Someone said it
could be a CRC-Failure. But I don't know exactly what this means. This
is my backup drive. So it would be critical if it is something wrong
with this disk.
