Please define "CRC errors" for me.
Do you have kernel log messages for them?
I want to know what device is complaining.
If it is a SATA drive, then triple check your SATA cabling,
and replace it if possible, because SATA CRC errors happen
only during transfer of data between host and drive.
The data on the drive is fine.
A bad or out-of-spec system power supply can also cause this trouble,
as can an overloaded system power supply.
