raid

I am a web developer. I have not much experience in hardware. For this reason, I use managed servers.

This morning, one of the drives in our setup failed. However, the full site went down. I asked my web host what happened and he replied that the hard disk failed in such a way that the RAID controller couldn't work properly.

Do you guys ever seen that before? Is it possible?

Thanks for any help on this guys. I need to know if my web host is honest with me.
