You Have Been Warned
The Arcadia IT User Service people don’t play around. It’s nice that they added a warning for all of the library patrons that they were going to perform maintenance on all the computers. Save your data and move them (and any viruses) onto a pen drive. The last thing you want is to lose your entire thesis.
But what if you didn’t read the notice? What if you weren’t there before 5 PM to read the notice and lose all of your data? Tough luck. If you rely on a shared computer to do your research, you should live in the library 24/7 to protect your files.
