ReadyNAS primary disk replication hanging

OK, after a OS reset, I am now back to where I was a few days ago, except I can also log in to Frontview!

RAIDar screen, left to right:

1. Overall status - solid yellow
2. Volume status - flashing green, "initializing 0% complete, time to finish 9 hrs"
3. Slot 1 Disk status - flashing green, "Channel 1, Seagate ...initializing, time to finish 9 hrs"
Slot 2 disk: Green indicator, "Channel 2, Seagate... 188 ATA errors."

Via Frontview, health status is as follows:
Disk 1 (2TB) - Status initialising
Disk 2 (1TB) - Status OK.

So it does look like I'm really back to where I was on Wednesday. Just checked again, it's at 3% and quoting 8hrs, 45 mins 'til
complete. I suppose I'll let it go until the morning and check again. Fingers crossed!
