OK, so lesson learned. Just because it builds correctly in a RAID1 |
40 |
array, that doesn't mean that the drive isn't toast. |
41 |
|
42 |
I ran badblocks on the three drive components and, surprise, |
43 |
surprise, /dev/sdc came up faulty. I think I'll just build the two |
44 |
non-faulty drives as a RAID0 array until the hard drive prices come back |
45 |
down to pre-Thailand flood prices and backup regularly. |
46 |

Thanks for all the help. |
