Problem

Asus Hero XIII on-board Thunderbolt 4 (Intel JHL8540) to Acasis TBU405 (Intel JHL7440) external enclosure. The TBU is recognized via TB Control Center, the Firecuda 530 is recognized as a Firecuda 530 and it can be interacted with normally via Seachest command-line utilities. Flashing the firmware in Win 11 Pro worked fine, since sector alignment does not work in Windows environment, Seaboot was used.

Seaboot (tinycorelinux) recognizes the drive as Firecuda 530 and it can be interacted with normally. 4096 sector size is shown as available.
However alignment fails with the error message shown on the screenshot.

Expected behavior

Sector size set to 4096.

How to reproduce

See screenshot.

Deployment information
