That you have media errors. On both disks.
You can try to recover with dd*rescue. Then run "badblocks" to try find the bad sectors, then overwrite them, or better, overwrite the entire disk (both). Finally, restore from backup.
I'd be inclined to just "dd if=/dev/zero of=/dev/sdX" over them. Provided there isn't a genuine fault in the drives, this will wipe them and fix any bad sectors. Bear in mind, trying to second-guess what the manufacturers have put in their firmware by way of error correction etc. is an exercise in futility...
I have never seen a positive comment about the WD Green drives.
I refuse to buy them (I bought a few 10 years ago. Bad results at the time.)
Seems to me, manufacturers are optimising the hell out of firmware for specific use cases, and forgetting that some of us want cheap general-purpose drives. As far as I can make out, "green" drives are optimised for *backup* or for laptops with oodles of ram that are configured to cache disk up to gunwhales and delay disk access as much as possible. They aggressively go to sleep, and don't like being woken up. Put them in a linux desktop and they'll go through their warranty (maximum acceptable sleep/wake cycles) in a matter of months. I want cheap drives I can put in a desktop raid - 5400 rpm is fine, SCT/ERC is a must, can I find the two in the same drive? NO! Who was the idiot that decided 3 minutes or more is an acceptable time for a desktop drive to hang when searching for data?! But any drive over 1GB certified for desktop use no longer supports SCT/ERC (the ERC standing for Error Recovery Control, ie allowing the user to tell the drive what to do if it can't read the data!). Properly certified raid drives are massive overkill for a desktop :-( I think about the only *real* reason for all these drive types is for shingled drives, where re-writing data comes at a real cost, but apart from that I think drives should have a "universal" firmware that can be configured to the user's requirements, and maybe a server and desktop variant that are built to different tolerances. Not oodles and oodles of different drives optimised for use cases that don't match user requirements. (Oh, and yes, I've heard very little by way of good stories about green drives, mostly because they are optimised for a usage pattern that does not match typical linux use.)
