Recover files from Windows install

I have/had a Windows server running the latest Seafile Server.

The C drive is a single 500gb for the OS
The D drive is a mirrored 750gb for the data (Seafile)

My C drive has failed this morning and I’m not sure where to go next.

My first plan was to plug one of the data drives into another PC and pull the data off it, but is that possible because of the format seafile stores the files? I cant see anything about using FUSE on windows? Open to suggestions please.
