When I run that command, sdd is my SDD drive, ironic I know. Anyway, it doesn't show block sizes. It returns nothing. root@fireball / # smartctl -x /dev/sdd | grep -A2 'Supported LBA Sizes' root@fireball / # This is the FULL output, in case it is hidden somewhere grep and I can't find. Keep in mind, this is a blank drive with no partitions or anything. root@fireball / # smartctl -x /dev/sdd smartctl 7.3 2022-02-28 r5338 [x86_64-linux-5.14.15-gentoo] (local build) Copyright (C) 2002-22, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Samsung based SSDs Device Model: Samsung SSD 870 EVO 500GB Serial Number: S6PWNXXXXXXXXXXX LU WWN Device Id: 5 002538 XXXXXXXXXX Firmware Version: SVT01B6Q User Capacity: 500,107,862,016 bytes [500 GB] Sector Size: 512 bytes logical/physical Rotation Rate: Solid State Device Form Factor: 2.5 inches TRIM Command: Available, deterministic, zeroed Device is: In smartctl database 7.3/5440 ATA Version is: ACS-4 T13/BSR INCITS 529 revision 5 SATA Version is: SATA 3.3, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Wed Apr 19 12:57:03 2023 CDT SMART support is: Available - device has SMART capability.
