Software and Apps Western Digital and SSD Dashboard

Hello. I noticed Media Wearout Indicator is wrong on SSD Plus. Tried to change on xml files but health stays same

SSD Plus disks have 15nm nand , so wear count spec is 3000  . I have 102 Average Erase Count. Media Wearout Indicator value is 0,03% . But it should be 102/3000*100=3,4%

I hope developers can fix this issue

Drive health not stable
Write amplification factor VERY high, wearout indicator not being reported correctly in software

How can i report issue to developer ? I checked ssd dashboard but there is no space about feedback…

Seems to be nobody is checking this forum

this may be a FW issue not related to the dashboard itself. Please submit a support ticket to sandisk support so they can look into the issue.

Both. ssdplus reports MWI in 1% frequency , ssd dashboard recognizes MWI as 0,01%. it can solved with firmware update or app update 

I will try to send a ticket. Thanks.

Hello ugurkrl,

Welcome to the SanDisk Community. As drlucky suggested can you please open a ticket with SanDisk support? Also when you open the ticket please include the full Dashboard report.

And i forgot , this drive really needs to be updated…

i bought a cheap chinese ssd for IoT board.It have sm2246xt too , WAF stucks on 1,7 even disk is full. But most of SSD PLUS and Z400 users have more WAF than 2,2. Its definitely not normal…

I bought a SanDisk SSD Plus 1TB at a retailer in October, 2022, and I originally installed it in my HP WIN 10 laptop, and it worked great. Then, I moved it into a TiVo DVR, and used it for a year or so. Then, my TiVo started developing problems about 6 months ago, and I debugged the problem (took 6 months!) and the other day I took the SanDisk SSD Plus out of the tivo, and I used CrystalDiskInfo to extract the SMART data from the SSD, and the Media Wear Indicator indicated a DEAD drive (even though it still worked albeit much more slowly than it should be). Then I used the SSD Dashboard from Western Digitial, and it too showed a bad drive as it has 0% health. What’s the deal? What happened to the drive? Are the SSD PLUS drives not rated to go into DVR’s? I reported this to SanDisk, and they are sending me a replacement drive. But, I’m beside myself. Are the SSD PLUS drives really as bad as the their common reputation I read about?
