I have a Windows Server 2003 R2 Ent server running with a C: drive and dynamic disk raid 1 Z: drive. The Z: drive mirrors two identical 1TB drives (same manufacturer, model number, and size – HDS721010KLA330). Amongst other things, the Z: drive holds the home directories. The 1TB drives have been installed a year ago.
Lately I've been starting to get very slow logins and when looking at the management console I noticed a few things:
- The dynamic Z: drive is resynching
- Only one of the disks of the dynamic drive is showing errors (a small yellow warning sign and "(Errors)" next to the drive status
- Even when the resynch is done, Disk 1 is still showing errors. And I don't know why but resynching is triggered again (haven't tested when)
You can see a screen capture of my disk management here:

So my questions are:
- Is there a way to get more details about the errors that Windows is reporting?
- Is this a faulty drive or possibly some other issue?
- What's the best way to solve this? I don't want to buy a new drive just to find out the troubles pop up again after a few months.
Thanks for the help!!

You have a faulty drive and will need to replace it. Right now you have no redundancy anyway, as the two drives will not stay synced, so if there is going to be any delay in replacing the drive at least disable it, as that will restore the performance.
