The system was BSoD-ed while a permission update was processing. After a reboot, the system can't recognize all the drives. When I start Disk manager, it stuck at the 'Virtual Disk' part. I set up the Windows Storage Space with parity and fixed configuration. I use 3x WD Re 4TB HDD. How can I recover the data? If I go data recovery company (ones with their own lab), how much will cost me (around 3.5TB data to recover)?
