I have two mirrored disks as D:\, and lately windows has been telling me D:\ is full though it's not. I suspect this is because there are some errors on one of the disks in the pool that is reporting imminent failure.

As it stands, very frequently I can't save any files to D:\ because the computer seems to think it's full.

I don't have the ability to purchase an identical drive for a couple of weeks and really need to get back to using my computer properly.

How can I break the mirror without data loss?

I set it up using storage spaces, and if I go that route to break the mirror, it says I will lose data. Is this true?

I found instructions saying to use Computer Management to break the mirror, but I didn't use CM to set up the mirroring and it won't give me that option.
