Newly Created Raid 1 Array not visible in windows 8.1

[JCzar]

Hi, I've just created a raid 1 pair with two 6TB dirves.

It shows as working fine in the RST application, it shows as a signle drive in windows Disk Manager, and as a single drive in Aomei Partition Assistant.

It is NOT visible in windows File Explorer.

Aomei shows that is is a GPT disk; so, the disk size should not be the issue.

I've uploaded the system report below.

Please let me know what changes I may need to make to get the array to show up in windows.

Thanks!

You may need to go into the Windows Disk Management applet and initislize/format its partition(s) there.

The partitions are already set up, but still the array is not visible in windows.

Are you sure? Creating the volumes in the RAID manager is not the same as creating partitions and/or formatting.

Yes I am certain. Both DM and Partition Assistant clearly show when a drive is partitioned.

With some experimentation, I have figured out that the drive will appear if the drive letter is set to G and is invisible if the drive letter is set to F. This occurs when using DM change letter function. Further, if I remove the letter entirely, then "add" F in DM, the drive will not appear. If I again change it to G, it will appear.

F was the letter used when naming the partition originally. No other drive on the system is labeled F.

Unfortunately, F was the letter that the array is replacing and because a large number of programs reference files on the F drive, I really want to set the letter to F.

Any ideas on what might be happening and how to fix this?

This seems absolutely bizarre - and definitely beyond my ken. Intel Customer Support will need to step in and look at this issue...
