How can you tell when a drive crashes in a RAID5 configuration?

Question: OK, this is probably a very stupid question with a very obvious answer.

If you have a RAID5 with four hard drives and a hardware RAID card, how can you tell if one of the drives crashes? Will it just keep going before you put a new drive back in so it can rebuild it?

It won't do any damage just installing the software and seeing it if recognises it. It just comes up and says 'no supported array controllers found'. I put a similar card in a ML310G4 the other day which wasn't supported by the ACU I had, but I think it may just have been out of date.

However if you look here Software and Drivers - Smart Array Controller HP Smart Array E200/E200i, Microsoft Windows Server 2003 you'll see you can download the ACU for your card (assuming it's the E200/E200i you have) so I'd assume it's supported. Also on here HP.com - ProLiant Storage - HP Smart Array E200 controller - Overview & Features it says your card has 'consistent software management tools' which says to me the ACU which works for most other HP controller should work for yours if it's up-to-date. In fairness to HP they're FANTASTIC for backward compatibility and compatibility between hardware, I'd be surprised if it doesn't work...
