It is still running (fan is on), but the screen has gone dark and won't come back.

 I'm certain that both of these problems have occurred before that

addition of the Maxtor drive, the latter referring to a mounted thumb drive then, but they have become much more frequent.

 Are these recognized problems and can anything be done about them

short of rebooting? If this has been discussed already, a pointer to the original thread will be fine.

Take a look at the system log for any messages having to do with sleep and USB devices.

Viewing Crash, Console, and System Logs

  1. Open /Applications/Utilities/Console.

  2. From the Console menu bar, select File > View System Log.

  3. From the Console menu bar, select File > View Console Log.

The system log will usually give you an indication as to what is causing startup issues. The console log can show issues you experience after you are logged into your user account.

If a particular application is crashing, you may find a crash log in /Library/Logs/CrashReporter/ or /Users/you/Library/Logs/CrashReporter/.

(Feel free to post the logs here if you need help understanding them. I'll be glad to take a look and tell you what I see.)
