Re: Really
"unless he did some useful local HDD wipes, that data can often be retrieved"
In this day and age, I expect everyone with a laptop that isn't physically bolted down, to be using an encrypted file system.
OTOH, a good IT outfit would probably keep the encryption keys on hand. But then again, stuff that you want to recover should already be stored on a server someplace, not on a disposable laptop. Hence the need for recovery should be nill.
As another poster suggested: Check the server logs.
