cathash doesn't produce the right hashes on XP

[pbatard]

As reported by Abid Bhat:

while using cathash.exe to calculate the hash of the following 3 files,
we are not getting the expected hashes.

Attached_update.sys_, if you may need. Please let me know, if you need
any other info

Sample Execution Results:
C:\Documents and Settings\Administrator\Desktop\cathash>cathash.exe
c:\WINDOWS\system32\driversupdate.sys

The CAT hash computed by this program differs from the Microsoft one!
expected: \174598107864fd544c59264fc9c5831c2ad8cce0
computed: \7580fc9e53e089eebdb3ed4dcf1f8ef93148c263

With XP being officially retired, I don't think I'll ever bother investigating this. Closing issue.
