We are using :pserver: (as we have some MAC and Linux clients)
I agree that this looks like a HDD problem, but any HDD errors should be reported by the OS and they are not.
I am wondering if buffer overflows inside CVSNT may be the cause. Corruption occurs on very large operations. i.e. while tagging 5,000 files, 3 of them get corrupted. There may also be other users performing operations at the same time. I sent out an email earlier describing the tagging operation timing out because another user was performing a lengthy operation at the same time. This is the main reason we set up a 2nd server and split the database. Also, the reason why I have 2 different versions of CVSNT is to test the current release. If all goes well :) I'll then upgrade the old one.

I would recommend either upgrading the old server to 2.5.02 or 
downgrading the new one to 2.0.51 so you can rule out CVSNT (or at least 
the change in CVSNT version) as the culprit.

In my experience, overwritten files is a sign of a bad HDD.  Assuming 
you aren't using :local: protocol across a network link (look for a 
network drive letter anywhere in your CVSROOT), I would guess hardware 
as the most likely cause.
