Preclear.sh results - Questions about your results? Post them here.

Correct.  After waiting for it  to complete. 

 

Joe L.

Test should be completed now. But `smartctl -a /dev/sda` yields the same output, except for the timestamp and Raw_Read_Error_Rate, Power_On_Hours and Hardware_ECC_Recovered fields.

 

I guess that's it then? Nothing else to try?

 

The difference would only be one line towards the bottom of the report.  Again, you're on your own... an SSD is a very different beast than a spinning disk and I doubt it implements SMART in the same way.

Just finished Preclearing this drive with the updated preclear.sh can you guys let me know how it looks good or bad thanks.

First, that is not the most recent preclear_disk.sh.  It is currently at version 1.6.

 

The disk looks fine.  There are no re-allocated sectors, nor any pending re-allocation.

No other attributes are failing now.

 

Enjoy your new disk, and always grab a new version of preclear_disk.sh before you clear a new disk. The final report on newer versions is much improved.

The temp never went above 30 degrees C, that I saw.  I don't remember seeing that change in SMART attributes before.  Is it anything to be concerned about?

Its fine, nothing to worry about.

 

I just finished 3 cycles each on 2 drives and my results were almost identical.

I figure nothing to worry about but figured I would ask the experts. I got these off ebay used and real cheap. So here are the terminal outputs from four drives. Attached are the Smart Reports. Thank you guys

Everything looks fine.  Two of the drives ( sdb, sdd ) had been exposed to high temperatures at some point in the past.

 

If you look at the finish report for them you'll see the normalized WORST value is below the FAILURE_THRESHOLD for that attribute on both of those drives.  They probably were used without any fans or cooling.  The temperature looks fine now.

Would someone mind taking a look at these results for me?

 

I've run this drive 3 times now (actually 4, but the 3rd time I was running it, my PC that I had the telnet session open on froze up during the post-read).

 

The first two times, I saw increases in the number of re-allocated sectors -- and the 3rd time, it stayed the same, but I'm concerned about some of the other values:

133 sectors had been re-allocated before the start of the preclear.

Should I be worried about the Raw_Read_Error_Rate, Spin_Retry_Count, End-to-End_Error, High_Fly_writes, etc?

 

This drive came out of a Seagate External Enclosure, and it's been working fine for me for a while now, I just want to make absolutely sure before I put it in my array.

Should I be worried about the Raw_Read_Error_Rate, Spin_Retry_Count, End-to-End_Error, High_Fly_writes, etc?

No, the current VALUE is above the affiliated FAILURE_THRESHOLD.  The manufacturer just happened to put the FAILURE_THRESHOLD at a value close the the normalized starting value on a few of the attributes.  Only they know how many errors are actually needed to fail. (and they aren't telling)

This drive came out of a Seagate External Enclosure, and it's been working fine for me for a while now, I just want to make absolutely sure before I put it in my array.

I'm more concerned about the re-allocated sectors.  If they've truly settled down, fine.  If not, not so good.

 

I've got one drive in my array with 100 re-allocated sectors and it has stayed that way no matter how many times I've pre-cleared it.  It too was re-used from an old USB enclosure.  All we know on your drive is it want through 1 cycle without re-allocation of any additional sectors, but the prior 2 re-allocated 133.

 

My vote would be to preclear it for 2 or 3 more cycles, and if stable, use it.  If it shows signs of re-allocating more sectors, RMA it.

Thank you -- I think I will run a few more pre-clears on it just to make sure.  The drive is fairly old, I'd have to go dig up some receipts to see if it's still under warranty (probably is, just need to make sure).

I just added a 3rd drive to my new unraid build.  The first two drives cleared with no issues.  I pulled an existing 2 tb drive from my PC that was working fine and tried running preclear.  It got to about 97% on the pre-read and then froze at that point (hung for several hours).  Initially I couldnt even kill the screen session.  Anyways.  I am trying to preclear again, however I get the following warning before running pre-clear.  Is my drive toast?

Are you absolutely sure you want to clear this drive?

 Anyways.  I am trying to preclear again, however I get the following warning before running pre-clear.  Is my drive toast?

Yes, there are two SMART attributes that are FAILING_NOW.

 

Be thankful you learned of the failure before you trusted the disk with your data.

There are 1265 sectors that have been re-allocated.

 

In highly technical terms, the drive is "toast."  I see an RMA in your future.

So I am doing a preclear on 5 Samsung F4's and I noticed something.

 

It is on step 2 and running fine save for one thing.

 

4 of the 5 disks are chugging away at 104-106 MB/s

 

the 5th one however is putzing at 23-25 MB/s

 

Is he the runt of the litter?

Could be, or, you might have the SATA controller set to an IDE/Legacy compatibility mode.

Hmmm, never changed anything in the BIOS, and all drives are conected to the MB SATA ports.

 

Only thing I see as different about this drive is its port, all the others are sda, sdb, sdc, sdd and this one is hda.

 

Kinda torked now too as my kid decided he wanted to play a game on the PC I had the Telnet sessions going on and rebooted the PC.

 

Gotta start them all over now.

if it is being shown as /dev/hda, then it is IDE emulation mode.  The BIOS has options for this, and possibly two different options, one for the first 4 port, the other for the remaining 2 disk controller ports.

 

The reason is simple, Windows-XP and prior have no SATA drivers.  If there was not an IDE emulation mode, you could not boot those OS.  Emulated IDE will usually be much slower than native SATA.

 

You can change the emulation mode at any time.  It will not affect the disk assignments in unRAID of affect the disk contents.

Well, I stopped the current run of preclear and went into the BIOS to check and this is what it shows (* = current setting)

 

OnChip SATA Channel -Enabled*

                              Disabled
