And another one shortly after.  Looks like Hardware ECC recovered counts up madly, none of the others change much.

I guess it depends which articles you read...

E.g. this article suggests as early as a year
http://www.larryjordan.biz/articles/lj_restore_hard_disk_data.html

Well, I can say my experience with a number of drives is different.  I've had a few of them that are years old and powered up and ran fine.

I recently dug out an old system that has Windows 98 on it because it has a 12 channel ISA video board that I was fixing a program for, booted it up and fixed the program without a hitch.  It hadn't been powered on for 4-5 years at least.  It was buried in the closet, I had to take a whole pile of stuff out to get to it!

Thanks for posting your results. Sadly I'm none the wiser. Your read error rate is zero. Your ECC value doesn't match the read error rate like mine. My spin-up time is zero and yours isn't.

In contrast, my new Samsung 2TB drive showed the error rate as 0 for first day or so and now is "1". It also shows a spin-up time value. ECC value is 0.

So I really have no idea what these figures actually mean.

I'm just looking at my data, and I think I need to use a different control to actually run a test.

How are you invoking the test?

I'd tend to agree. I was wondering at a basic level if running a rsync across the drive "refreshed" the data. I'm just paranoid.

To get the print out? Same as you did: smartctl -a -i -d marvell /dev/sda

OK, that's all I'm doing.  I was thinking I needed to run the SMART test, but in looking closer, I see that all I should have to do is to print the accumulated SMART data.

Don't know what to tell you, maybe it's time to go drive shopping! :D

An rsync doesn't take nearly enough time to refresh all the data on a drive!  :o

You can run the various SMART tests (short/long etc) if you like. That's all tools like Seatools actually do.

Presumably, the data must be read from the drive in order to compare it with the destination? That article suggests that hard drives automatically refresh the data when reading it - unless I mis-read.

IMO, that's pure BS!  I'm beginning to doubt what these guys are saying overall!

Could it mean that the platters are remagnetised by the heads or something. I have no idea :)

The only way to "refresh" data is to do a write operation.  This is basic magnetic physics.  In point of fact, the continual passes of the head, if they did anything, would tend to erode the data.

All that I read about long term storage of hard disks is you're more likely to have a problem with the drive spinning up again due to dry bearings or the like.

If the data is REALLY important, there are archive quality DVD-R/+R media that is supposed to last a long time.  Save the data on a hard disk and on the DVD, and compare them every year to verify both copies are still intact.
