hi all,

 

Just a quick question with a drive I've just finished preclearing.

 

I've precleared a few other disks that all came back looking fin from what I can tell but this one was different.

It's telling me a SMART command failed.

 

What does all this mean?

 

thanks Josh

hi all,

 

Just a quick question with a drive I've just finished preclearing.

It's telling me a SMART command failed.

 

What does all this mean?

Your guess is as good as mine.  It seems to indicate the first smart test failed.  Perhaps SMART reporting was not enabled on the drive, or it was not initialized as expected....  Or it could be one that SMART is unable to address in some conditions.

 

I'd try a quick test with

preclear_disk.sh -t /dev/sdh

command to be sure the pre-clear actually completed.

Hello!  This is my first pre-clear ever so i was just wondering if i need to be concerned or re-run it or whatever.

Column headers are:

 

ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE

 

Look at the "VALUE WORST THRESH" values.

 

As long as VALUE is above THRESH your OK.

 

Most helpful.  Thank you.

 

I'm going to add the headers to the script output.  ;D

Just spent the past week preclearing six 2TB drives.  Not sure if the results are good or not, but one of the drives took forever to finish.....about 3-4 time longer than the others.  Do my results look ok?

 

Thanks,

jeff

I noticed they are all EARS drives.  Did you place the jumper on pins 7 & 8?  Should normally take about 30-40 hours to preclear a 2TB drive. Were all 6 drives pre-clearing at the same time?

Yes, all drives have jumpers on pins 7 & 8.  I started 4 drives preclearing at same time including the slow one (sdb). After the first two completed, I started up the next two.  Never had more than 4 running at same time.  Drive sdd was precleared twice because I forgot to save the results the first time.

I ran the disk speed test and all drives except sdb were above 100 MB/s.  Drive sdb was 25 MB/s...ran the test again and it was 1.24 MB/s!  I decided to switch this drive to a slot where one of the higher performing drives was and also replaced the jumper and it gave 90 MB/s and the drive that I moved into sdb old slot was still pretty high at 107 MB/s.  Strange...still not sure if it's safe to build the array??

Perhaps the problem was a bad connection with the jumper??

Despite the speed anomalies, do my preclear results look ok?

 

I built the 15 Drive Budget Box listed here http://lime-technology.com/forum/index.php?topic=7998.0

 

my latest speed test results are below...

 

/dev/sdb:

Timing cached reads:  3556 MB in  2.00 seconds = 1778.70 MB/sec

Timing buffered disk reads:  324 MB in  3.01 seconds = 107.66 MB/sec

 

/dev/sdc:

Timing cached reads:  3572 MB in  2.00 seconds = 1786.67 MB/sec

Timing buffered disk reads:  326 MB in  3.00 seconds = 108.61 MB/sec

 

/dev/sdd:

Timing cached reads:  3558 MB in  2.00 seconds = 1779.21 MB/sec

Timing buffered disk reads:  318 MB in  3.02 seconds = 105.31 MB/sec

 

/dev/sde:

Timing cached reads:  3326 MB in  2.00 seconds = 1662.72 MB/sec

Timing buffered disk reads:  272 MB in  3.01 seconds =  90.43 MB/sec

 

/dev/sdf:

Timing cached reads:  3552 MB in  2.00 seconds = 1775.83 MB/sec

Timing buffered disk reads:  354 MB in  3.02 seconds = 117.39 MB/sec

 

/dev/sdg:

Timing cached reads:  3564 MB in  2.00 seconds = 1782.33 MB/sec

Timing buffered disk reads:  340 MB in  3.00 seconds = 113.26 MB/sec

Please have a look to my results, does the drive have any problems?

Not really sure what do do next, do I have a useless/almost dead drive here?

Not really sure what do do next, do I have a useless/almost dead drive here?

 

Was this a brand new drive when you started?

 

There were 38 pending sectors when the preclear began.  A pending sector basically means that the drive thinks it is a bad sector but has not been able to reallocate it yet.

 

After there preclear, you have 44 reallocated sectors (this means that the drive has marked them as bad and "mapped" spare sectors to replace them).  This is a good thing, as if effectively repairs those bad sectors.  But you also have 149 pending sectors.  There are also 44 reallocated events (representing the 44 reallocated sectors).

 

This is a pretty bad condition.  You could run another preclear cycle on the drive.  If the drive is good, you'd expect that the 149 pending sectors would get reallocated (leaving 193 reallocated sectors, and no pending sectors).   If that happened, and the count didn't increase under stress, the drive would be ok.  But the odds are way against that happening.  When this many sectors are being reallocated it is normally downhill.

 

Long story short - you don't want to trust your data to this drive.  RMA it.

When I see a disk with a lot of sectors pending re-allocation after a pre-clear it indicates the sectors were un-readable in the post-clear read.  (If identified in the pre-read, they should have been re-allocated when written with zeros)

 

The other possibility is a poorly regulated power supply, causing read errors. Or, drive electronics sensitive to noise on the power supply lines.

 

Right now, I see a drive with a fair number of re-allocated sectors (44 ) and a lot more pending re-allocation ( 149 )

 

I'd run another pre-clear cycle, and if the numbers continue to increment, RMA the drive.

Thanks a lot for the prompt help guys, I've done another pre clear on the drive and it doesn't look good.

I agree, it does not look good.

However SMART still says the drive has passed so can I still RMA it?

Yes, you can still RMA it.  (and you should RMA it... it is returning many un-readable sector errors.  It does not look like they'll get better with time)

After my disastrous start using WD15EARS drives, used with XP, no jumper and ran WDAlign, I now have 2 new WD20EARS drives, so just to check I'm on track with things I have posted the preclear results for 1 drive.

 

Conditions.

 

1) The drive is new from WD

2) Has not been used in any system other than unRAID and preclear.sh

3) I soon as I unpacked it I placed the jumper across pins 7 & 8

4) I then ran preclear.sh

Looks perfect.
