Theodore,

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          31      248976   83  Linux

38829073 < 522133279
so it tries to reach beyond the physical boundaries of the disk

Possible as one of the errors that pop up is aborted journals, and journals
take off-line and what not.

e2fsck finds millions of issues, I always give fixing a try but after minutes
of pressing enter to fsck questions I give up and re-install debian (takes 15
minutes)
