Contacted Intel Customer Service. The suggestion given is to install this HDD on another computer for data recovery. I used EaseUS, which helped me recover most of the data (but there are still a lot of data lost, unable to open, no file name, No directories etc.). After the recovery is complete, Optane is bound to a 1TB hard drive for game acceleration, but it is no longer used on hard drives with important data. Therefore, I suggest that everyone, Raid0 is a terrible thing, a little carelessness may cause data loss, so when using Optane memory, be careful not to use it on the hard disk with important data, and always back up your important data in Private cloud. Hope this post can help people who are using Optane memory.
