A hardware error should have been reported as such. But if you
suspect a disk problem, try dd'ing the swap partition (or the whole
disk) to /dev/null. If you can read the whole partition, you can
probably write to it. (Or you could dd /dev/zero to the partitions
whilst swap is not attached - eg in single user after boot). If you
suspect retries are a problem, monitor the I/O rate with iostat or
systat and see if it suddenly drops.
