That is expected behavior.  Windows does not recognize the file systems used by the NAS.  You will only see the disk listed in the windows disk manager.

As I said, you need to connect all the disks to the PC at the same time.  You cannot recover files from a single disk, because of the way the RAID is constructed.  The data is "striped", so the files are spread over all the disks.

Also, as I said above, you will need to purchase RAID recovery software to access the files on the disks from Windows.  This will let you copy the files, so you will need additional storage to copy them to.

Which software you need depends on whether you ever converted the NAS to OS-6.

If you never converted to OS-6, then you can use something like R-Studio

You'd need the license listed on the far left ($79.99) as that supports linux file systems.

If you did convert to OS-6 (or aren't sure), then ReclaiMe Ultimate will work.

However, it is quite a bit more expensive.

You can download these packages before purchase, so you can see whether they can find your files before you buy them.
