Most likely you got some bad sectors on it. As I wrote earlier, this
is one of the first signs something is wrong with the disk. Start
planning purchace of new disk. You can run diagnostics on the disk
(usually downloadable from disk manufacturers support web site) to
check the health of the disk and reallocate any bad sectors found.
However, in some cases once you start getting first bad sectors, they
just keep multiplying exponentially (if they are caused by loose
particles inside the disk flying around as disk spins).
If disk is still under warranty, I'd contact manufacturer immediately
(like right now, this second). Once I made a mistake of "fixing" the
problem couple of months before warranty expired. And it seemed to
work OK, no more errors or such. Disk failed completely couple of
months later, just after warranty expired. Of course, manufacturer
(Fujitsu to name it) declined my warranty request (I'm not blaming them
here, it was my stupid mistake that I haven't contacted them as soon as
I saw the first error message logged by the kernel).
