harshl Posted February 24, 2019 Share Posted February 24, 2019 Dropped a couple of these (CT500MX500SSD1) into a buddies server for a cache tier and started seeing these messages within 24 hours. Seem to be getting them sporadically now, several times a day. Appreciate everyones feedback, nice to know it is not a failing drive on this particular model. I will open up a ticket with them as well just to make a little more noise. Thanks! Quote Link to comment

Keep in mind this is not an unRAID problem. This is a bug with Crucial and they have not resolved it yet. This error is reported by multiple platforms and not limited to just unRAID. I'm actually considering abandoning these devices and going with Samsung. In the meantime, disabling attribute 197 works around the problem and silences the false positives. You still have attributes being watched to keep track of reallocated sectors (you're not totally blind to a drive going bad). Quote Link to comment
sminker Posted February 25, 2019 Share Posted February 25, 2019 Another one over here. New CX500 500GB drive. About three weeks old. Getting the error since installing. I use it for my plex appdata (got tired of the mover taking forever when upgrading cache drives). This is going to make me avoid Cruicial SSDs for a while. Never had an error with any of my samsungs, SPs, or Sandisks. Some are 3-4 years old. Quote Link to comment
Zervun Posted April 8, 2019 Share Posted April 8, 2019 Chock this up for another person with the issue. Will open a ticket with crucial as well as this is annoying. I have 8 of 1tb mx500's, all bought at different times over the past few years. The 4 I have in unraid all periodically report "current pending sector is 1" and then clear. Immediately after reporting field 197 of smart shows 0, so it must resolve very quickly. Quote Link to comment

I have 8x 10tb shucked WD whites for spinners/array with 2 parity drives of those. I haven't noticed the error on my esxi cluster, might not have the smart notifications setup right on that, or it is because it is on a dell h710 controller doing hardware raid in a dell r720xd and that error may not be noticed on the h710 The other 4 mx500's I have are on a ESXI cluster. (I have way too many servers about ~200 TB total, ESXI, Unraid, Freenas, Synology) Edited April 8, 2019 by Zervun Quote Link to comment
Richjfree1 Posted April 30, 2019 Share Posted April 30, 2019 OK, I have one of these in my cache pool. it is was less than one week old when I began receiving the notifications...I pulled the drive and connected it to a windows machine to update the firmware after reading this thread. only to find that it has the current M3CR0023 firmware. I have disabled notifications of attribute 197 as suggested in this post... I probably can return the drive to amazon since it is so new, but I don't want to bother if there is no consequence. anyone have a recommendation? Quote Link to comment
RichardU Posted April 30, 2019 Share Posted April 30, 2019 There is no consequence that I know of other than the nagging feeling that it is not right. 1 Quote Link to comment
VSC55 Posted June 16, 2019 Share Posted June 16, 2019 Hi, I have 2x SSD CT250MX500SSD1 and the same thing happens to me. This problem is not only in Linux, since I am using them in Windows 10 and the errors also appear from time to time. Quote Link to comment
Kash76 Posted June 20, 2019 Share Posted June 20, 2019 I purchased two of these drives and am getting the same error. Can someone please help me, where do we disable this warning? Quote Link to comment

dr0 Posted August 29, 2019 Share Posted August 29, 2019 (edited) 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?

Fraih Posted October 17, 2019 Share Posted October 17, 2019 Any news about this? My MX500 is arriving in a couple of days and I know I will have this problem, but it was a good deal and the performance is close to the Samsung drives. Any script to turn off the warnings as unnasigned device (keeping the monitoring of other unnasigned devices on). Thanks! Quote Link to comment

It's a shame... But as long as the SSD works as expected I guess it's not too bad. It would be nice to be able to desactivate the attribute 197 having the disk as unnasigned device, hopefully the plugin will be updated with that feature some day...

Yeah, but I wanted to avoid disabling that attribute on my unnasigned mechanical disks Quote Link to comment
bonienl Posted October 18, 2019 Share Posted October 18, 2019 There is nothing that Unraid can do to solve the issue. Have you tried Crucial and ask them? Quote Link to comment

whiteatom Posted November 28, 2019 Share Posted November 28, 2019 I still this issues is still not fixed.. Just got a great deal on an MX500 that i'm using for Plex under UA and I open the unRaid UI to about 20 notices from this drive every time. Looking for the uncheck of smart attributes now.

JorgeB Posted October 31, 2020 Share Posted October 31, 2020 Looks like this issue is finally going to be fixed with smartmontools 7.2: https://www.smartmontools.org/ticket/1336 Quote Link to comment
