I've got a 3TB WD Green drive that flip/flops pending sectors.  One pass it's 65535 then next it's zero then 65535 then zero etc.. for at least 6 passes.  I'm going to RMA since the last pass left it at 65535. That was the highest I've ever seen too. 

<snip>

It's just a bad drive >:(.

Wow... really buggy firmware.    It should never do that... 

 

I'd stay clear of that make/model/firmware;

Device Model:    WDC WD30EZRS-11J99B1

Firmware Version: 80.00A80

Thanks for the reply on my slow preclear Joe. I am seeing the following errors:

Strangely though, it looks like later in the log those errors are showing for a different drive:

Advice? Are these drives hosed?

Link to comment

The number 65535 is not 65 thousand something, it's the unsigned integer representation of the 2 byte signed integer value of -1, so I wouldn't put too much significance in it.  A return of -1 is usually a flag value, indicating a possible error or the current unavailability of the true number or something else but not a valid return value.  If possible and I saw a value of 65535, I would grab a few more SMART reports, to see if it would change to a valid value.  If not, I'd reboot and check again.  If still not, then I would have to assume a bug in the SMART functions of the drive's firmware.

 

As to the End-to-End error, I'm not sure we should give that much significance either, because it is a relatively new attribute, and looks to me to be still experimental.  That does not mean it is not significant, it IS informational, but the SMART reports where both of these occurred (this one and one a week or 2 ago) both indicate that this was flagged 'Old_age' not 'Pre-fail', and therefore this is NOT considered a critical attribute.  Since it is not considered critical, it is only informational, and as such that may be useful, but I'm not sure it should carry much weight in your decision making.

 

There are many critics of the SMART system, and both of these situations just give them more ammo.  Some don't trust SMART reports at all, but I feel that once you understand and have some experience with the vagaries and inconsistencies of SMART numbers and report info, then there is useful info there.  I just wish they would get their act together a little better.

Thanks for the reply on my slow preclear Joe. I am seeing the following errors:

Not hosed, but you do have some bad sectors on 2 drives, sdd and sdb.  You also probably have a bad SATA cable to the drive sdb.

Link to comment

Thanks Rob. Which error indicates the bad cable?

 

These drives are connected via a 4 port SATA card. Could that have something to do with it? (I haven't noticed errors for the other two drives on that card though.)

 

This error line, with the BadCRC flag set:

Feb 27 16:10:51 Bunker kernel: ata2: SError: { BadCRC }

It indicates corrupted packets across the cabling.  That is almost always a bad SATA cable, easily replaced.  It could also be a power issue to the drive, but if it was a power issue you would probably have had more BadCRC errors on other drives too.  Since you didn't indicate any others, it's probably a bad cable to this drive.

 

Both drives, after the bad sector handling, indicated "configured for UDMA/100", so I figured you must have them connected to an older disk controller, with UDMA/100 speed only.  That is going to significantly impact their read and write speeds.

Or, it could be somebody who has tie-wrapped all the SATA cables together, or worse, tie-wrapped them to power cables,  making it neat looking, and inadvertently  maximizing the noise pickup potential from one to another.  (In other words, making the likelihood of induced noise CRC/corrupted packets issues much higher)

 

Memo to builders... do not bundle unshielded SATA cables..  It is a recipe for CRC errors.

I haven't tie wrapped any cables together...but I'll admit that I was tempted to do that before closing my case. I'll make sure I don't and will re-route SATA cables to spread them out a bit more.

 

I went back and double checked my log and don't see any other CRC errors, so hopefully it's not a power issue.

 

What's the best way to keep an eye on this? Just check the log periodically while using the drives? Should I preclear again with a new cable to test?

 

Do the bad sectors indicate a drive that is nearing end of life? Is it still worth adding these to my array?

 

The SATA controller card is from Monoprice and it's SATA I, so yes it's slow. I think it'll be fast enough for my media streaming and I do have a cache drive to help with write performance.

 

Thanks again for all the info guys. I really appreciate that the unRAID community is so responsive and helpful. I definitely have a lot to learn.

FYI.  The drive I posted about has been in a box to RMA back to WD several times and now several months (just haven't had the opportunity to start the process yet).  I got it out last night and put it back in my preclear station to get the smart report - like I've done several times before.  The 65535 is a permanent reading until I initiate another preclear cycle.  It also isn't always a 65535, 0, 65535.  The first set of 3 preclear cycles I ran was 65535 cycle 1, 128? cycle 2 and 0 cycle 3 - so I thought it was a good drive.  The last time I ran a cycle of 3 (there may have been other cycles in-between) it was 65535, 0, 65535.  So I haven't run one since so that it is in that state when I send it back to WD.  So far every time I put it back into my preclear station(s) (I have two cpus that I clear drives on) it comes back with the same smart report I posted above.

I agree with Joe, that combo of drive model and firmware is not confidence inspiring.  Any chance of a firmware update for it?

Probably - I've got some 2TB greens with 81.xxx I believe.  At this point unless it is out of waranty I'm not going to mess with a firmware update - just RMA the drive.  I have 2 other 3TB models - they may all be the same model - will have to check when I get home.  Only one of the 3 is working correctly.  The other problem drive is slow and has some of the same smart errors as this one just not the pending. 

 

At one point I really liked the green drives - have 30 currently.  But have 12 with smart errors I don't trust - multi zone, read errors etc... another 12 were perfectly fine until I fried them with a case fan that died and they got to ~60c on a parity check.  Of the 6 2 TB drives left in working condition at least one is slow now - 30 MB/s parity checks when in array.  I finally got the drives replaced with Hitachi/WD Reds in 2TB and 3TB sizes in my 2 unRAID servers.  I could RMA most of these but I no longer have a good idea of which ones were over heated and which ones weren't.  I don't think they should pay for my mistake anyway and I can use them for offline backups until they are dead.

Sorry for asking this again (And I'll probably be asking a few more times) but I like to have a second opinion from someone who knows this stuff more than me.

Other than the read speed, it seems okay to me, but, like I said, I'd rather have a second opinion on this.

Sorry for asking this again (And I'll probably be asking a few more times) but I like to have a second opinion from someone who knows this stuff more than me.

<snip>

Other than the read speed, it seems okay to me, but, like I said, I'd rather have a second opinion on this.

Looks like a perfectly fine drive to me.

 

Only issue, probably in its prior life, are the power off retracts

192 Power-Off_Retract_Count 0x0032  200  200  000    Old_age  Always      -      284

These were where power was turned off when the disk heads were still loaded.    (apparently you just hit the power switch) however, the normalized value of 200 has not budged, and nowhere near the failure threshold of 0, so no need to worry.

Just pree cleared my new 2TB disk, any concern ?

Would this value increase if I had something along the lines of a BSOD? There was a phase where I literally had BSODs every minute, and, I wouldn't be surprised if I racked up at-least 200 in the time it took me to fix it (Which was just saying "Fuck it" and reinstalling windows).

Also, this is another drive that finished preclearing overnight. It seems to have a different read value that what it thought it wrote and failed the preclear. Is there anything I can do to attempt to fix it? It's out of warranty so no RMA.

Just pree cleared my new 2TB disk, any concern ?

 

======================================================================== 1.14

Version 1.14 of the preclear script does not exist here, and I wrote the preclear script.  I only go up to 1.13.

 

Sorry.  you'll have to go to its author for analysis.

Sorry for asking this again (And I'll probably be asking a few more times) but I like to have a second opinion from someone who knows this stuff more than me.

<snip>

Other than the read speed, it seems okay to me, but, like I said, I'd rather have a second opinion on this.

Looks like a perfectly fine drive to me.

 

Only issue, probably in its prior life, are the power off retracts

192 Power-Off_Retract_Count 0x0032  200  200  000    Old_age  Always      -      284

These were where power was turned off when the disk heads were still loaded.    (apparently you just hit the power switch) however, the normalized value of 200 has not budged, and nowhere near the failure threshold of 0, so no need to worry.

 

Would this value increase if I had something along the lines of a BSOD? There was a phase where I literally had BSODs every minute, and, I wouldn't be surprised if I racked up at-least 200 in the time it took me to fix it (Which was just saying "Fuck it" and reinstalling windows).

Yup, that would do it.

Also, this is another drive that finished preclearing overnight. It seems to have a different read value that what it thought it wrote and failed the preclear. Is there anything I can do to attempt to fix it? It's out of warranty so no RMA.

I'd say use it in a "Windows" computer, where an occasional crash or data corruption would never be noticed.  ;)

 

Unless it is power supply related, there is little else you can do.

Would someone be so kind to cast an eye over this, it's an old drive I used in a WHS build.

Thanks very much guys, especially Joe for all his hard work!

Would someone be so kind to cast an eye over this, it's an old drive I used in a WHS build.

Looks fine other than this

It appears as if the disk has gotten as high as 48C degrees.  That is a but higher than I like to see.  (I prefer to stay under 40C)

Make sure the disk has enough cooling.  The preclear shows it got up to 42C in it.  so it is not just in its old life where more cooling is needed.

Thanks very much guys, especially Joe for all his hard work!

You are welcome.

I just picked up some new drives the other day and was going through the preclear but seem to have hit a snag. The first disk precleared with no problems at all. The second however seems to fail for some reason at either 36% or 37% on the disk pre-read everytime I try to run it. It will just seem to stop reading and the script will no longer update. Any thoughts are greatly appreciated.

It's probably getting bogged down, waiting for the drive to deal with all of the bad sectors.  Current count of reallocated sectors is 3168, and there are 4904 bad sectors still to be dealt with, and as you said, it's only gotten through about a third of the drive.  Not good.
