<p>And I guess one more question... I was not able to learn much
about these errors from the interwebs, but perhaps they don't
necessarily suggest an actual drive failure but some sort of soft
problem with the array - perhaps repartition the bad drive and add
it back to the array and hope the errors don't come back? The
errors look scary to me, but most people on this list have a lot
more sysadm chops than I do...</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>
