I hate to say "don't use SATA" in critical production environments, but I've seen this situation quite often. SATA drives are not generally meant for the duty cycle you describe, although you did spec drives specifically rated for 24x7 operation in your setup. My experience has been that SATA drives can fail in unpredictable ways, often times affecting the entire storage array, even when using RAID 1+0, as you've done. Sometimes the drives fail in a manner that can stall the entire bus. One thing to note is whether you're using SAS expanders in your setup. That can make a difference in how the remaining disks are impacted by a drive failure.
But it may have made more sense to go with midline/nearline (7200 RPM) SAS drives versus SATA. There's a small price premium over SATA, but the drives will operate/fail more predictably. The error-correction and reporting in the SAS interface/protocol is more robust than the SATA set. So even with drives whose mechanics are the same, the SAS protocol difference may have prevented the pain you experienced during your drive failure.
Upgrade the firmware of your RAID controller and all devices. The best approach in your situation is to download a current HP Firmware Update DVD (it's bootable), and let it run updates on all of the devices.
Early firmware on the E200i controllers would give false-positive drive failure alerts, etc. It'd best to try to bring everything up to the current revision level.
Try this first. If there's no difference, we can look at the Array Configuration utility to see what it thinks the status of the drives is. But this is more likely to be a firmware problem.
Edit:
Your array setup is messed up!!
From the server's perspective, you only have THREE active disks. These are the disks in bay 1, bay 2 and bay 3. The drive in bay 1 is your C: drive. It is a RAID-0 and has NO redundancy. Bay 2 and 3 contain a RAID-1 mirror holding your D: drive. No other disks appear.
At this point, I'd check the physical connections of the drives and the internal cabling to the E200i controller.

If you're running Windows 2008 on this system, you will want to use the HP Array Configuration Utility in either its graphical or command-line form. For the purposes of this question, I'd recommend the command line utility.
Once installed, you will want to navigate to your Programs Menu and open the Array Configuration Utility (it may specify "command line").
Once inside the utility, run the following command:
ctrl all show configThis will output something like:
If any of the output indicates failed or pre-failure, that's enough evidence for HP to send a replacement disk.
Once you've verified that there's a bad disk. You can identify the drive with its blue LED indicator. In this case, I would use the following command to identify the drive:
This will blink the drive in question for one hour.
As for the mechanics of drive replacement, you need to identify the disk, press its release lever, open the drive handle, then remove the disk. Installation is done in the reverse order.
If you're interested in adding more disk space to the array, see these questions on Server Fault...
