1) The disk is borked. The fix is obvious. Googling for the error shows one guy saying his Western Digital disk failed the WD diagnostics, but the SMART was OK. You do realise the the "SMART status: OK" is completely useless? Its only use is when it says "FAILED". Pity it says "OK" for long after the disk is usable. Perhaps that guy made that mistake. The relevant numbers are: reallocated (depending on age and size of disk, some are permissable - if it goes up suddenly, save your data FAST), pending, offline uncorrectable. The last 2 being non-0 means you have a problem, but you don't know which disk blocks it is on. Run a long selftest and check how that completes (replace disk if failure). 2) Your USB hardware has problems. Frequently that involves not having enough power for the disk; it doesn't happen for self-powered disk enclosures. Bad contacts, cables, damaged (but not completely blown up) silicon are all possible. 3) Your kernel's USB drivers are faulty. Ubuntu problem. 4) Your application software is fooling you. Some people are blaming gnome 3. That's why you immediately quit all the fancy stuff, log in on a text console, and use ls, cp, cat etc. to verify where the problem is. Always check syslog (/var/log/messages) and the output of dmesg (the interesting bits are at the end). 5) The filesystem on the disk is kaputt. Data corruption problem. Solutions fill a different book, follow your nose. Try fsck. 6) Several problem descriptions from google strongly suggest to me that there is a mismatch between the size of the filesystem and the size of the disk partition it is on (incompetent creation of filesystem, maybe a camera or other device). I'd expect that problem to show itself while writing, but people seem to be getting it while reading - no idea.
