Its a Toshiba PX05SRB050 listed in spec sheet with 500GB, but the divice size is only 200GB.

Any idea how to resize it back to the maximum of 500GB?

It's likely overprovisioned. You can disable that with sg_format. You'll probably need to find the exact sector count with hdparm first though.

Its a SAS SSD.
hdparm don't work for SCSI

I'm aware that you can't resize SAS drives with it, which is why I said to use sg_format.

I used sg_format to reformat to 512 Sector Size
I'm currently reading in on the topics:
DCO (Device Configuration Overlay)
AMAC (Accessible Max Address Configuration)
HPA (Host Protected Area)

lshw -class disk shows for the device:
size: 186GiB (200GB)
capacity: 372GiB (400GB)
