My 2 drives are the same type, and the second just got its first reallocated
sector. The temperature of the second drive is elevated a few degrees
because it just did a read test for a few hours, but it's usually the same
or a few degrees higher (it's in a removable drawer with its own fan).

What I'm puzzled about is why would the "Hardware ECC Recovered" and the
number of reallocated sectors have an inverse relation between the 2 drives
(I marked them with *)?

Also, does "Ultra ATA CRC Error Rate" refer to errors on the ATA cable? If
so, the higher number on the second drive might be due to the connector
(centronics) in the drive drawer (a StarTech). The Value column for "Ultra
ATA CRC Error Rate" looks pretty bad. Would you trust any drive drawer for
ATA133?

Sorry but you might have to switch to a fixed font if you want to read this.
I appreciate it.

Too small of a statistical sample. Maybe you just read more from the
drive with the higher ECC recoverd number. BTW ECC recoverd does not
necessarily mean the sector was bad. It could just have been a not too

the implementation.

It does.

If it works, then it works. If not, the OS may decide the drive is
unusable and disable it (until reboot). The error rate looks still
reasonable to me.

There are people that read usenet with non-monospaced fonts?

Nothing to worry about with Maxtors they deliberately ship
their drives with some questionable sectors in use and let
the drive reallocate them if they turn out to be unusable.


Those temps are fine.

Coincidence.

Yep.

Yep, that flouts the ATA standard and you can clearly
see the downsides of flouting the ATA standard there.

Nope, I'd use a SATA drive if I needed that functionality
and even some of those flout the SATA standard too.

Yeah, the Everest report is a tad wide too.

Of course, you're right. The drive with the higher ECC recovery number does
get read more.


Thanks.

Thanks for addressing all those issues. I'll replace the drawer when I can.
