Hello
Thank you for your question and reaching out. I can understand you are having query related breaking mirror.
What is the difference between the ‘Break Mirror’ vs the ‘Remove Mirror’ option?
The “Break Mirror” operation, will stop the mirroring on the selected volume, without affecting the data on any disk. (Data will remain untouched on both disks).
The “Remove Mirror” operation, will stop the mirroring on the selected volume and destroys all the data on the mirror disk. (Data will remain only on one disk).
What option to choose? Break Mirror or Remove Mirror?
The decision between breaking or removing mirror, must be based on your needs. For example: If you need extra space on your system then choose the “remove mirror” option, but if you want to use the disk in another computer, in order to use your current Windows configuration, then you must choose the “break mirror” option. If you don’t know yet what to do, then prefer the “Break Mirror” option, which keeps all your data in both disks intact, until you decide.
I assume its Windows Mirror you have used.
I would suggest to use the Disk Management and break the mirrored volume.
Disk Management -> Mark Mirrored Volume Set -> Right click and choose "Break Mirrored Volume"
