I've seen similar and noticed drives used for TM tend to fail more than other HFS+ formatted drives. One of my hunches is that SMART is not to be trusted and the repeated spin-up, do stuff, spin down of TM on those drives is the cause. The other is that rarely you will in fact get a garbled data packet over USB where the CRC happens to match.

But when I test the drives with badblocks, nothing shows up. The hardware is fine -- I write bytes and it gives them back to me when I read.

I suspect it's because Time Machine works by creating tons and tons of symlinks, which the HFS+ driver does not like. Regardless, it shouldn't be possible for a userspace application to corrupt the hard drive by creating a lot of links and folders.
