Failing boot sector?
Some other sector it has to read is failing?
Check the logs. Try (from smartmontools):

  I don't know exactly which of your questions/suggestions running:
~
  smartctl -A /dev/sda | egrep -i "sector|realloc"
~
  relates to, but it didn't report any error message. Without grep I got:
~
$ sudo smartctl -A /dev/sda

Ok, your disk is dying. The Raw_Read_Error_Rate should be zero, or very low.

   7 Seek_Error_Rate         0x000f   075   060   030    Pre-fail

That is also seriously bad.

Is this a fairly new disk? Only 2678 hours use.

It looks like many errors have been recovered using ECC, so you probably wouldn't have noticed those.

It *is* possible that smartctl is mis-interpretting the status of your disk, but given your slow fdisk command I suspect not.

Time to backup, backup, backup, buy a new disk and transfer the data over asap.
