Milly is right. This is the result of bad sectors on the harddrive where the
PST is located. Run the command Milly suggested and then use scanpst.exe to
try and correct any errors in the PST file - you may have to run it multiple
times.

You might want to run chkdsk /r from a command prompt to see if your disk has some bad sectors.
