Iāve noticed the exact same issue.
In my case, sda is an unrelated/unmounted NTFS disk which keeps spinning up. sdb for the old Windows installation + ESP. Linux root is on sdc.
First Iāve thought udisks2 keeps triggering that issue, but this is not the case.
However, the disk seems to be re-appearing constantly, spinning up only to be put back to sleep immediately after.
Iād be happy to get your advice on this issue.
