I received 2 identical refurbished units from Asus. They both had prior customer data and settings. (ie they didn't wipe them)

One would not boot the win7 OS, but booting a live CD I saw customer data in Documents and the email client had been set up. The other did boot but into a German locale, and I needed a password if I had wanted to get to a desktop.

In both cases I wiped the drives clean to the bone with Darik's boot-n-nuke, as these were to be set up as servers running Linux.

Ironically, they were purchased without an OS, that's the main reason we selected these two. Yet they both had win7, I could have used the recovery partition and had "free" win7 boxes.
