USB Formatting Capacity Limit
Hello guys, Quick help pls? Running OS 6.1.1 1 - I have a USB 3.0 to SATA Dual-Bay USB 3.0 Hard Drive Docking Station attached to my NAS which was previously with two 3TB disks and now th...
So just to confirm, the 4TB drive is only showing 2TB?
That is correct. If I format the disk using Frontview and chose NFTS it will show only 2TB. If I format and chose Ext4 or Ext3 things get even worse and it shows only 512KB or MB (can't remember really)
Please try formatting it on a Windows PC as well.
That's what I did and when I do that it works perfectlly and shows the full capacity 3.64TB

That suggests there's a bug in the NAS formatting.
It works fine here on both 4TB and 6TB drives. That suggests a problem with the partition table on the drive.
What do you mean by partition table problem? This disk is brand new and was one of the disks installed in the NAS. I replace it by an 8TB disk and decided to use it in the USB dock station for backup purposes. As I said, when I plug it into Windows it formats very well and shows the full capacity. The only thing I can't remember right now is if I converted the disk into GPT on Windows. You think that could be the problem? I can be wrong but to have a single volume in a 4TB drive I need to use GPT right? or should I use Dynamic?
Tks,
Yes, GPT is the correct choice.
The NAS "Format" function does not actually repartition the drive (to prevent accidental data loss), so what actually got formatted was probably the root or swap partition.
