 Posted: Mon Aug 27, 2012 11:36 pm Post subject: Crucial M4 SSD 128GB + gdu-notification-daemon :( [resolved] |
 |
|
Not sure this fits anywhere, and surely not a Gentoo issue...
Anyone have a Crucial M4 SSD and run Gnome?
gdu-notification-daemon keeps on reporting that there were lots of relocated sectors. And it's true, when I smartctl -a the SSD, there are thousands in the column for raw value - I get as below in smartctl and something like 110K in palimpsest. (My other SSD in my workstation (Intel SSD520 series 180GB) does not look like this...)

The SSD controller does not think it's a problem else it should have failed it as Pre-fail.
I don't see any real issues with the disk so far, it seems to be reading/writing just fine, getting in excess of 500MB/sec on sequential reads.
For now I've disable gdu-notification-daemon but it would be nice for it to report real issues... or is this really a real issue and Crucial should expect a RMA?
[RESOLVED]
It looks like this is "NORMAL" and Crucial won't fix this by replacement.
I guess gdu-notification will need to be modified to accommodate this issue...

how about: write crucial support a nice email and ask for clarification?

I wonder how Linux friendly they are... once they ask me to run some-diagnostic.exe for Windows support do will I get shot down...
Update:
I got an email response back from them. They basically say unless it's failing it's not failing... Ugh...
So that means I have to fix gdu-notification-daemon to do what I really want...
Looks like my next SSD may be another Intel... or something...

I found Micron/Crucial's documentation for SMART fields so I added this into my SMART database:
| Code: | {
"Crucial M4 series",
"M4-CT.*M4SSD.",
"00.*",
"",
"-v 170,raw48,Grown_Fail_Blocks -v 171,raw48,NAND_Program_Fail -v 172,raw48,NAND_Erase_Fail -v 173,raw48,Avg_Erase_Count -v 174,raw48,UnexpectedPowerLoss -v 181,hex48,Unaligned_Accesses -v 183,raw48,SATA_Downshifts -v 189,raw48,FactoryBadBlocks -v 202,raw48,Device_Life_Used -v 206,raw48,Write_Error_Rate"
},
|
This makes it a bit more clear what the unknown fields are:
| Code: | 1 Raw_Read_Error_Rate 0x002f 100 100 050 Pre-fail Always - 0
5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 55296 (0, 1)
9 Power_On_Hours 0x0032 100 100 001 Old_age Always - 264
12 Power_Cycle_Count 0x0032 100 100 001 Old_age Always - 66
170 Grown_Fail_Blocks 0x0033 100 100 010 Pre-fail Always - 59
171 NAND_Program_Fail 0x0032 100 100 001 Old_age Always - 0
172 NAND_Erase_Fail 0x0032 100 100 001 Old_age Always - 0
173 Avg_Erase_Count 0x0033 100 100 010 Pre-fail Always - 1
174 UnexpectedPowerLoss 0x0032 100 100 001 Old_age Always - 8
181 Unaligned_Accesses 0x0022 100 100 001 Old_age Always - 0x00460009003c
183 SATA_Downshifts 0x0032 100 100 001 Old_age Always - 0
184 End-to-End_Error 0x0033 100 100 050 Pre-fail Always - 0

Still unsettling it had so many bad blocks from the factory... And I don't know why, despite my partitions being 4K aligned, is still reporting unaligned accesses...

basically, "It's normal" and no new disk unless value is less than threshold for SMART failure....
I guess this means that even though the bad blocks were "grown" it's time to change software to accommodate...

Thanks. I won't buy a Micron/Crucial.

Yeah I don't know, suppose that's the way to go if you don't want any chance of annoyances... still see a lot of people with good disks, might have to "stress test" this disk for the heck of it... But with SSDs, pretty much everything is logged, not sure what can really be done...
The Crucial/Micron is still very fast, and no lost data yet...
Need to get more samples though, this is just one...

I think I've had Samsung & Intel on my list, but haven't kept up with prices. I'm considering a few for some systems.

They've all come down a lot. So far I'm pretty happy with my Intel 520-series SSD.
