Before you do anything else, do smartctl -H /dev/sda (and then repeat for /dev/sdb). If that tells you one of the disks is failing then that's probably your problem. I don't know if BadCRC above refers to a media or an interface error.
Also smartctl -t short /dev/sda (and again, same for /dev/sdb), then smartctl -l selftest after the prescribed amount of time to check the results.
Thanks for the suggestion, I'll try that next time I get access to the system.
If it's working fine on Windows then it's probably not a hardware issue as you say, but SMART makes it so easy to do cursory checks, it doesn't make any sense not to start there.
The PC was working well on Windows, but not with those disks. One of the 2 SATA disks has been part of a RAID-Z array on another system for some time and the other is a new SATA disk to replace it. The situation is that I have a server with 5*4TB disks in a RAID-Z array and I need to replace it with 5*6TB disks. As I have no system that can handle 10 disks I need to use several PCs to copy the data. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
