<p>I'm not certain how to be sure. A quick duckduckgo search
suggests that 4k native sector also being marketed as "Advanced
Format" - is that right? Looking at the Toshiba spec page, I see
AF listed as "Yes" for the 8T (the first drive I tried) and "No"
for the 4T (which also didn't work).</p>

<br>
Out of curiosity, are the new drives "4K native" sector drives,
and is this the same as the old drives you're replacing? If the
system's old enough its BIOS might not support that & is
expecting to have "512n" (512-native) or "512e" (512-emulated)
sector-size drives.<br>
<br>
Other than that, I'm not sure what it could be beyond being
Toshiba brand (which I've personally never had good experience
with, but that's only anecdotal).<br>
