I had a few spare moments the other night while I was upgrading our mail server so decided to have a look at the Windows 7 Beta I had installed earlier on virtual box.

While I was doing some benchmarking I happen to get an error on copying a file and couldn’t help but laugh.

Now I figure this is actually a CRC error as the file I was copying was incomplete, but I guess I now know Microsofts plans to improve copy performance in Windows 7, they are going back to dos.
