Also, anyone with any network design sense would vlan & firewall the ATMs off of the rest of the network.
Yes, it's Windows. But without crazy Aunt Judy trying to install her cat screensavers Windows should be fine for the task.
Anyway, I like your policy.
For the folks (family and friends) that seem to think I'm a free computer repair store I told them to go buy a cheap USB hard drive and just set up a quick and dirty batch file to back things up nightly (or weekly, depending on how big their files are).
I've told them to do this or there's a good chance that I won't be able to recover their files if their PC crashes. This is an easy solution, cheap, and requires virtually no end-user interaction. That last bit is especially important since I've found that they typically ignore even the easiest backup procedures (e.g. copy C:\My Documents to D:\).
As for the original question, I still do attempt file recovery for the stubborn ones who ignore my backup advice. I've had moderate success with various pieces of software. Just Googled "hard disk recovery software." Interestingly enough, different programs have recovered different data on the same HDDs...
Can someone explain to me why this is controversial? SANS is one of the leading security organizations in the world...
