I have a new portable 4 TB HD - Armor A85 I (USB 3.1) would like to use for back-up. I try to partition it to two drives using Acronis Disk Director but got the following log/ error: "Cannot process 'Disk 4' because its sector size is unsupported (4096 bytes)." how can I partition it? Is there any advantage having sector size 4096 VS 512 bytes (which is requested by Acronis DD)?
https://www.partitionwizard.com/partitionmagic/mbr-vs-gpt.html I would also recommend using their free partition software. It can do non-destructive partition resizing and can even undo most operations if you do something dumb. Large sector sizes can be read faster, but can be wasteful if data is not filling the whole sector. Most format routines will opt for bigger sectors for bigger partitions. This is a compromise. The smaller the sectors, the more will fit in a partition. The more sectors you have to remember, the bigger the file system data is and less space for your actual files.
Diskpart, list disk If it was my HD I'd make it GPT, single 4 TB partition. You can do all this in Windows Disk Management.
