Bit of background:
1. I have the F4-210 and for a while only ran two HDDs in it. A 2GB HDD and a 4GB HDD. I don't quite remember what file system I used, but they were run in JBOD.
2. I have recently bought three extra 4TB HDDs so that I can run a Raid 5 across all 4x4TB HDDs.
3. I now have a spare 2TB HDD that had some data on it.
Question:
How do I move the data from the 2TB HDD back onto the NAS? I've tried to connect the HDD directly onto my desktop PC (Windows 10). Whilst it recognises a 1.8TB partition, it doesn't let me mount it as a drive on Windows:
.Is there any way I can back up the data from the 2TB HDD back onto my NAS (either on Windows or through TOS itself?).
Thank you!
