Hello, Arno!
You wrote on 24 Feb 2006 12:35:54 GMT:

Thanks for the interpretation and advice. As noted, drive 3 is a RAID array
consisting of 2 identical Maxtor drives (RAID0). Best I can tell only one
drive (1/2 of the capacity) is being reported so I'm not sure what the smart
data source is. Guess if it fails I will have to separate them and test them
as non-raid. May do that before they fail by booting on other
drive/partition.

One other question - how does on run a long SMART test?

Thanks,

Colonel Blip.

Good question. Depends on the controller, I guess.

You should do that as soon as possible. You can e.g. have them as
single disk on an IDE controller and use a Knoppix CD to boot. The
SMART tool there is smartctl (on the commandline).

I suse smartctl, which is a Unix tool, but also works under Windows.

For long self-test use the following commandline:

smartctl -t long <device>

268 bad sectors replaced out of millions of spares is absolute peanuts.

1883 reallocated sectors out of millions of spares is peanuts.

Not with those absolute numbers. Perhaps they were accumulated during
a very short time and that that had an effect on the Normalized values
decreasing faster. If the problem stops the normalized values may return
to more normal values with time.

It's a RAID, babble box. Which one?
The numbers are likely faked anyway.

If the crash coincided with power failures, sure, why not.

It does on some.

Nope. Some drives can retest bad sectors and reformat tracks so that
Logical Block Addresses are sequential again.

With some drives but not others.

Not with those absolute peanut numbers.

But it may take care of still pending ones.

Urk, those are extremely high except for Drive 2 obviously.

Nope.

Nope, the drives have already added those bad
sectors to the bad sector list and they wont be
removed from that by restoring an image now.

What is the brand/model detail of the drives ?

Show the full SMART data for all drives, that may
have some extra useful info like the temperatures too.

Following is the full smart info. The drive in question is the 3rd one,
which is actually 2 SATA 80gb Hitachi drives on a Via m/b controller setup
as RAID0.
Here is info on the Hitachi followed by the SMART for all three. The 2
Hitachi drives are identical.
