DrivePool only created 2TB partition on 4 TB drive

[wtown]

Not sure if this belongs here or in the Hardware section, but here's my question:

I added a 4TB drive (Seagate Ironwolf) to my drive pool, and let DrivePool format it. For some reason it only created a 2 TB partition, and left 1.6 TB unallocated.

Any idea why this happened?

Can I just extend the partition using a partition management tool, or should I remove it from the pool and reformat it at full size?

No idea why it happened but I'd suggest removing it from the pool and recreating the partition at full size yourself, with a full (not quick) format, just to ensure there's nothing off with the drive.

It's been a while, but IIRC, some older AF drives can act weirdly.  But if there is nothing on the disk, then repartitioning it would be the best bet.
