Thanks for replying, Stan. I am not actually sure what are the bare, required facts, so I had just tried to include the information that I could obtain from mdadm. At this point, I have been running GNU ddrescue (e.g., ddrescue --cluster-size=65536 --no-split --force /dev/source /dev/destination /.../log.txt) to transfer two of the complete drives to two of the larger four drives that I have. No errors have shown up whatsoever so far, which jives with the SMART results. In a couple of more days, I should have all four copied over, then I could try risk writing to the four larger drives. I know that the set of 4 drives had been set aside for quite a while. They were completely out of space. I booted the recovery disk for a couple of reasons. One was that when I booted normally, they had shown up with one marked as failed. However, there seems to be no actual error, so I can only guess that prior to having set them aside some time ago, I had failed one on purpose in order to install a larger drive and begin a migration, but got interrupted by life's events. The other reason was that I had (mistakenly) thought it would be a good idea to use the recovery disk as an environment from which to migrate the data to larger drives. I was also adding hardware to support port multiplication (don't have 8 sata ports onboard) and thought it would be helpful to be running a relatively bare-bones setup.
