I think there are a couple of buggy IDE interfaces out "in the wild"
that do this -- corrupt the odd bit or two under some circumstances.
For example, from /usr/src/linux/drivers/block/README.ide:

| IMPORTANT NOTICE:  "CMD" EIDE Interfaces will not (by default) work 
| *reliably* when drives are attached to the second interface.  To "fix" 
| this, supply the special kernel "command line" parameter to LILO:    
|    hda=serialize
| Failure to do so can cause severe data corruption!

It's possible this may be the problem.
