My unraid 6.4 works great and no issues at all.

 

But sometimes I need to powerdown unraid and restart the system into native Windows 10 64-bit.

 

Is there a way to read the contents or map to the unraid drives under windows?

 

I do not need to have write access, but if it is possible even better, but I do not want to risk to srew up the unraid disks.

 

thanks

Short answer, no.

 

Long answer, maybe, depending on the format of the drives. Definitely not recommended, windows has a habit of messing with drives even when told not to.

 

Don't do it, the risks are too great, even if you can work out a way.

Ok. thanks for the advice.... definately not worth risking things just to listent to my music collection,  or too lazy to re download some drivers 

The only way I know of to access XFS format disks under Windows is via XFS Explorer.   That is safe as it is read-only access, but it is only suitable for data recovery and not ad-hoc access.   

 

This limitation is one of the reasons that many people want to run Windows in a VM rather than dual-booting.   Running Windows in a VM solves the problem in that the VM can access unRAID files via the network shares.   The possible limitation on this approach is that your hardware needs to support VT-D (CPU and motherboard) so that the GPU can be passed through to Windows.   The upside is that the machine can carry out both roles simultaneously.
