OK, guys. Thanks for your help! Things are getting interesting now...I've been running the badblocks test via tmux for the last 55 hours. Unfortunately, I can only see 5 panes (out of the 6 I think I should have), and, looking at the Disk Activity report, my fears have been confirmed -- my 6th drive has not been bad blocking. However, more concerning than that is the display from badblock. EACH of the drives that is being tested shows a display very close to the following:
90.66% done, 55:53:30 elapsed. (0/0/654598 errors)
I didn't think much of the last number because all of the drives were similar, with numbers ranging from 596095 to 661385.
Running smartctl -A /dev/adaX gives me a clean bill of health (I think). Here's a sample:
Code:

200 Multi_Zone_Error_Rate 0x0008 200 200 000 Old_age Offline - 0
So, my thought is that the drives are not "really" bad, but am I misinterpreting the readout, or do those error counts through badblocks actually mean something? I have the SuperMicro X10SLL-F motherboard. I may need to look at the hard drive controller settings in the BIOS, I'd imagine? Any other ideas?
Thanks!!
