Windows 2008 Enterprise mirroring error msg "All Disks holding extents for a given volume..."

I'm running Windows 2008 Enterprise on a single disk desktop with a 500gb Hitachi HDD. I tried to add a Seagate 500gb HDD for mirrroring, but when I tried to add the unallocated Seagate, I got the error message: "all disks holding extents for a given volume must have the same sector size".  I ran the FSUTIL command and the information shown for both drives is identical with the exception of the MFT start zone address. ( both have 512 sector size).  I noticed the capacities were about 1mb different (with the new drive being larger). Could this be the issue? and if so, what I can do about it? BTW, I seem to remember mirroring resizing the added unallocatted drive, so why doesn't it do it now?

This is the problem of the new advanced format drives. One of your drives is 4K and reports to interface emulated 512bytes format. But Windows detects the difference.
Check th drives with Crystal DiskInfo: http://crystalmark.info/software/CrystalDiskInfo/index-e.html
See if there is difference.

I installed and ran the program you suggested above, but I don't see any report of sector size, just dynamic performance numbers. How do I find the sector size for each drive?

My bad. I was sure I got this info once I run Crystal DIskInfo. Installed it again and confirmed that such info was not give there.
Dell had once a tool which could check this: http://www.dell.com/support/home/us/en/555/Drivers/DriversDetails?driverId=NXCXK&osCode=WLH&fileId=3075594713

Try it. If it won't run on your server then give full model numbers of both Hitachi and Seagate HDDs. We can try to find our on their websites if these drives are real 4K.

P.S. If you enter this command in CMD (Run as Administrator): wmic DISKDRIVE get bytespersector, caption
What does it report? Both 512?

I tried WMIC and the resulting log file is attached. I can't read the results because there is no formatting, but I do notice there is the text "512" under both drives, and "4096" is not found anywhere. Doesn't this mean neither drive is AF? If so, what should we do now?

I just tried the Dell AFDT tool you suggested, and wouldn't you know it, the new drive is AF. WMIC didn't report it that way. ERRRR.  I guess that solves the problem. I'm going online and order a second drive of the identical model number as the original. That way there can be no question. Thanks for the help.

Cool. Sorry for a delayed answer, was too busy :)
WMIC was showing the file system layer thus it showed 512 bytes.

Take care,
