Hi,

I have been using the same disk that is Linux formatted in my F4-210 NAS system for a while until I updated to Mac os Big Sur. It now reads the disk really slow through NAS and if I take the disk out and use USB to directly plug into my Mac it shows "The disk format is not supported".

I did some research found out Big Sur stopped supporting all windows/ Linux disk format and I cleaned my disk and formatted it to be APFS. Then I put it in my F4-210 NAS system to initialize the disk but it tells me to format it back to FAT format. which is reasonable bcs it needs the format to write down the operation system.

I wanna ask is that possible that if I use another empty disk to format to be FAT and initialize my NAS system and plug in my APFS disk on the second bay, will the system recognize the disk and work as normal?

Thanks!

All disks installed on your TNAS will be formatted before they can be accepted by the system.

Your TOS OS only uses ext4 formatted disks in the internal drive slots. If you regularly want to move a disk between the TNAS machine and other systems you can format fat or ntfs and connect to the external USB port. There's probably a utility for apple to read fat or ntfs.
