I have created a RAID 1 (mirror) array with 2 hard drives. The RAID is built within Windows as dynamic disks; i.e., there is no hardware RAID controller. Now I need to store a backup file to one of them. Consider this scenario:
- Windows is shutdown
- System boot from USB drive
- A process for creating backup file initiated
- A file was written to one of the disks from the RAID array.
Please note that this operation is done when Windows is not running. So here are two questions:
- Will this operation corrupt the RAID 1 array? If a stored file is deleted before Windows runs, will Windows see any problems/errors? Will Windows spot this operation?
- What will happen if Windows starts when this file is on the one of disks?
The question is mostly to try it out, but I do not have any unused drives to experiment with, and the RAID drives contain sensitive information.
OS is Windows 10. RAID is built as Windows dynamic disks.
