Change in the remaining life, instability and SMART

Hi,

 

In september I bought an SSD Plus 240G to substitute the 120G version (this disk was placed in another notebook). After the change I reinstalled all the system (Windows 7 x64), but there is some troubles.

 

- I have noted that the "remaining life" is decreasing very fast compared with the 120G that had no change during more than 6 months. Now it's in "98%". I tried to check the SMART when I noted this. The fast test run without problems but the complet test stops and return the code "27" (stopping at 10%).

- Besides that I noted many instabilities in the system. Many times the system crash. The screen stops to respond but the indicator of the disk shows some activity. This happen principally when I'm using the Chrome navigator. Many times the system crash after returning from the suspended state and this did not occur with the 120G version.

 

Thanks.

Re: Change in the remaining life, instability and SMART

Health indicator is wrong (i sent a ticket about this issue and nobody cared)

Disks health frequency is 1% but program reads as 0,1% .

Can you post screenshot of SMART section ?

Hi ugurkrl,

 

My system is very unstable after replacing the SSD.

ssd seems pretty healty. 

Maybe problem caused by 2nd disk.Try to reinstall windows. Probably problem isnt caused by ssd.And check disk connectors on pc.

And if you are sure , i recommend to install ssd to another computer , if problem still persists , ask sandisk for RMA.

Re: Change in the remaining life, instability and SMART

This is strange. Why the second disk is causing problems and when I was using the 120G version there is no problem?

 

The system was installed from zero when I change the disk, using the most recent image of Win 7 and installing all updates. There is no chance to reinstall all the system just to test and find de problem.

 

Now, the Dashboard is showing 99% of remain life (change form 98 to 99?), no sense.

There is no error in SMART report and health cant decrease again... You should ask for RMA to sandisk. There is some serious problem in ssd / firmware and SMART can't detect it. 98 to 99 is really strange , obviously faulty controller , faulty firmware or faulty nand issue.

Re: Change in the remaining life, instability and SMART

And 

"A9 100 100 __0 000000000000 Total Bad Block" Attrib is zero , this is unpossible on 15nm MLC ssd . Only SLC drives can shipped without any factory / initial bad block , even SLC drives there will few bad blocks...

Mine is 20 , most of people have around 15-50 initial bad block but you have 0 . Bad QC test , initial bad blocks didnt marked after production. 

another thing is : Host Reads : 3342 GB
Host Writes : 2018 GB
NAND Writes : 656 GB

Thats impossible too with DRAM-less ssds without any compression .Waf is 0.318 . I didnt notice any of those when i wrote first reply but it does makes sense now , ssd fails when writing blocks. It cant even update SMART report or bad block list , initial bad blocks wasnt checked during production.

Only RMA can fix this issue

Re: Change in the remaining life, instability and SMART

Can you share the SMART data from the SSD Dashboard ?
