I have very similar problem with my i386 6.1-STABLE installation. With
6.0 there were no problems. I have already eliminated bad hardware
(memory, hard drive) and also overheating. I'm able to reproduce the
problem with quite small files. 23 megabytes has been enough to get
corrupted. I have softupdates enabled and the disk is an IDE drive.

There however is one small difference compared to your situation. I
had a Java package in the root partition and after upgrading from 6.0
to 6.1 I reinstalled the package. The package was corrupted even
though I had used that same package before to install the Java
run-time to the 6.0 successfully. I haven't touched the file in any
way between the installations. I also has experienced multiple
corruptions while copying files. Usually I have to copy a single large
file three or four times to get it without problems. With smaller
files (less than 20 megs), there hasn't been any problems.

Next I'm going to downgrade my installation back to the 6.0 and see if
the problem will go away.

I'd be interested to hear if anyone else has experienced same sort of
problems with 6.1.
