So FreeNAS threw this at me this morning:

Odd, but "Warning: ATA error count 0 inconsistent with error log pointer 1" didn't sound good so I put in an RMA with Crucial which they accepted right away... then it occurred to me that I should check the other 4 drives in the array and smartctl returns the same thing. False alarm? Why did FreeNAS flag the error on only one drive? Should I cancel the RMA? Panicked over nothing?

It's a firmware bug on all CX500 SSDs, you'll get a single pending sector from time to time, it will then return to 0, you can ignore that.

FWIW, the June 19th 2018 MX500 firmware update didn't fix this. Got the error on two of the five drives today.

I was directed to this thread after having pretty much the same issue. Do we know if Crucial aware of this problem, or if a fix in development?

Got the same thing today on 2 of my MX500 drives which are brand new.

Firmware Version: M3CR023

I live-chatted with Crucial about this. My objective was to find out if they're aware of the firmware bug and if they're working on a new firmware. I didn't expect much from a chat person, but they didn't have a tech support email listed...

Spoiler alert: The agent doesn't think this is a firmware issue...
Katy P (6/6/2019, 4:36:49 PM): Hello, you are chatting with Katy, how can I help you?
Katy P (6/6/2019, 4:40:01 PM): Hello, are you there?
Me (6/6/2019, 4:40:09 PM): Hello. I purchased 14 MX500 1000Gb SSD's for use in a FreeNAS server. Long story short, these drives randomly throw "smartd[58718]: Device: /dev/da## [SAT], 1 Currently unreadable (pending) sectors", where "da" represents a number of these SSD's
Me (6/6/2019, 4:41:49 PM): After doing some research, I hear that this is a firmware bug in these SSD's. My question is Crucial aware of these issues and working on a new firmware? The last firmware did not resolve the issue.
Katy P (6/6/2019, 4:42:17 PM): I am sorry to hear that. Give me a few moments to look into this.
Me (6/6/2019, 4:42:26 PM): Sure.
Katy P (6/6/2019, 4:44:59 PM): Okay so at the base the error looks to be indicating bad sectors on the drive. It is not uncommon for SSDs to show a number of bad sectors but that doesn't necessarily point to a fault on the drive. You can find our details on why this can happen on our Knowledge Base page here:

https://www.crucial.com/usa/en/my-ssd-has-bad-sectors

I would also recommend running our own dedicated Storage Executive software, which can evaluate the health status of your SSD and accurately read the SMART information. You can find details on this at the following link:

http://www.crucial.com/usa/en/support-storage-executive
Me (6/6/2019, 4:47:21 PM): For what it's worth, FreeNAS runs on FreeBSD (as opposed to Windows, so Storage Executive won't run), so this might be an issue with the OS rather than FreeNAS.

Also worth noting is that the drive passes smart diag tests without sector errors.
Katy P (6/6/2019, 4:49:52 PM): That is quite odd. But if you need to test the health of a drive you can always connect it externally to a Windows system and use our tool to check it.

As a side note, the Crucial MX500 is a consumer grade drive and is not intended to be used in servers. Use in servers can shorten the lifetime of the drive and can even void the warranty depending on the TBW.
Me (6/6/2019, 4:51:33 PM): I understand that, but it being the few drives with power loss protection, among other features, it should make an otherwise excellent NAS drive...
Katy P (6/6/2019, 4:52:03 PM): Did you have any further questions while we're here, or was there anything else I could help out with at the moment?
Me (6/6/2019, 4:52:54 PM): Server use or not, ultimately my question is if the dev team is working on a new firmware for this drive that addresses this issue. If the answer is no, that I'd like to add this into the suggestions box per say.
Me (6/6/2019, 4:53:10 PM): That's all.
Katy P (6/6/2019, 4:53:26 PM): I do not believe this is an issue with the SSDs firmware.
Me (6/6/2019, 4:53:53 PM): I see. Ok thank you.

By the way, @Brian Stretch , 45 C seems too hot for a drive, although maybe it doesn't matter for SSDs, I don't know.

Is it possible to set attribute 197 to ignore for specific drives?

Also, could this be an issue with the smartd database not having complete information for crucial mx500 drives?

No, it reports a pending sector, then it goes back to zero, it's the attribute's raw value that's changing.

While I am not (yet) using FreeNAA, I am facing the same issue on CentOS, even after spending a ridiculous amount of time upgrading the firmware.

I am wondering how long it will take until Crucial will address this? Maybe we should start spamming them on twitter as nowdays they only care about brand visibility.

Both posters here have a high temp of 56C and 50C, way too high in my opinion for a properly cooled system, BUT the technical specs for these drives is 0C to 70C operational temps. So this is probably not the issue.

Is it possible to set attribute 197 to ignore for specific drives?
Yes it is, in a round about way. You can run a script to run your SMART tests vice having FreeNAS use it's internal testing. Then you can send out the results and if you think it's a problem, change the Subject line of the email to "PROBLEM" or some other warning that catches your eye. I have a two scripts for my drives (short and long tests) that does something similar and you can use a script in the resources section to do the same type of thing, then modify it to your specifications. It's all very doable if you take the time to learn how to script and use what is already out there. Here is the link to the resources I was talking about.

As for any other fix, don't be waiting on Crucial or you could be waiting a long time. And as for the checking of ID 197, I would set my script up to ignore a value of "1" but not anything else. If you find that you are seeing higher values then evaluate the situation and if the values are up to "2", maybe ignore those too but if it starts creeping up, maybe it's not the drive for you? Or you could just ignore a higher value if you desire. But I would not ignore ID 197 as a rule. You could also compare previous data to current data and see if it ever goes back to "0". Lots you can do.

Good luck!

On this note, I emailed them on the issue. The good news is that they confirm it's effectively a false positive and that it should be reasonably safe to ignore. The bad news is that they seem to have no interest in fixing this 'The Boy Who Cried Wolf!' firmware.
Hello Sam,


Thank you for contacting Crucial Support.


The pending sector attribute is legacy number from traditional HDDs, where there could be multiple blocks pending because they’re quite slow at processing them. SSDs on the other hand are expected to have a pending sector at any given time, as this is its natural way of evaluating if a sector can be corrected or should be retired.

So the number you are seeing is entirely normal and should be ignored if any utility is flagging it.

Micron has a Linux distro of our Storage executive software you are free to download to verify the integrity of the SMART health if you would like, but I can tell you before even trying that it’s going to flag the drive as healthy, since the pending sector count of 1 is normal as previously discussed. This is assuming all other attributes are healthy on the drive, which they presumably are, otherwise SMARTCTL would have flagged them as well.

MX500 SSD's firmware often throwing 'Device: /dev/ada#, 1 Currently unreadable (pending) sectors' errors. Firmware needs fix to make MX500 drives less 'false-positive error' prone in systems like BSD.
So yeah, if you really want a firmware fix, ya might have to start doling out some negative PR...

Not the answer anyone wants to see but it is an answer.

A few weeks ago I bought a 1TB MX500 for my personal system [i7-3770/32GB RAM/H77/GTX1050Ti/Win 7 x64 SP1] to replace a combo of a smaller SSD and an HDD. My MX500 also has this weird behavior when occasionally the drive reports attribute #197 (Current Pending Sector Count) to go from 0 to 1, but in a few minutes, it changes back to 0. Reallocation Event Count (#196) never changes and always stays at 0.



I have never seen anything like this with any SSD that I had a chance to use. My other SSDs have 10s of thousands of hours of active use and 10s of TB of lifetime writes but not a single one of them have pending sector(s) in the log files, including my trusty Crucial M4 that I've been using since 2011, whereas my MX500 has only 0.68TB lifetime writes and only 91 hours of active time but already had 3 events of pending sector. I wonder what causes this? And if it's indeed just a firmware bug then why Crucial hasn't fixed this to this day, after more than 18 month of MX500 being on the market?

That's rather optimistic when speaking of firmware of any kind.

It might not strictly be a bug. The parameter might mean something other than what your tool is telling you. Crucial's tool should be right, smartmontools has a decent chance of being right. Or it might be normal operation with just a bit too much noise that doesn't make sense to expose to users.

I ended up setting -i 197 as a SMART option on the MX500s I have a couple days ago, and that seems to be preventing the log errors and emails from showing up. It's not ideal as I guess if a sector goes bad, I won't know about it. But I was getting so many false positives I'd never know anyway.

Never mind, this doesn't seem to work for some reason.
