Yesterday my T430 with MX100 Win10 64 bit , started to show error on the storage (with the Lenovo Solution Center)
I have installed smartmontool , I there was a read/write error as per below:
Complete error log: SMART Extended Comprehensive Error Log Version: 1 (16383 sectors) Device Error Count: 5 CR = Command Register FEATR = Features Register COUNT = Count (was: Sector Count) Register LBA_48 = Upper bytes of LBA High/Mid/Low Registers ] ATA-8 LH = LBA High (was: Cylinder High) Register ] LBA LM = LBA Mid (was: Cylinder Low) Register ] Register LL = LBA Low (was: Sector Number) Register ] DV = Device (was: Device/Head) Register DC = Device Control Register ER = Error register ST = Status register Powered_Up_Time is measured from power on, and printed as DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes, SS=sec, and sss=millisec. It "wraps" after 49.710 days. Error 5  occurred at disk power-on lifetime: 3331 hours (138 days + 19 hours) When the command that caused the error occurred, the device was active or idle.

I then installed the Crucial CSE , and no error was showing , the SDD was good health :

Should I be worried ? who should I beleive ? Is there a real issue with the SSD ?

Do you have a screenshot of the Lenovo Solution Center report? Lenovo's software wouldn't do any UNC scans like smartmontools would, so I am curious what it's flagging. Typically 3rd party drive health programs from manufacturers are not designed to work with different brands of drives, or are tuned for HDDs not SSD analysis, so it's not uncommon for them to flag otherwise healthy drives.
The UNC (uncorrectable error) report from Smartmontools in itself isn't anything to necessarily worry about, if the actually SMART data was showing any unhealthy attributes then the combination could be a concern, but the SMART attributes are otherwise healthy. Your drive has 9 Reported Uncorrectable Errors over a span of 3,331 hours, which isn't that abnormal. There is an exceedingly high amount of power cycles on the drive, basically once every hour which in itself isn't bad, but it could accelerate any UNC creation. I would suggest disabling disk sleep under the windows power settings, since this is likely what's cycling power to the drive on a regular basis.
- Go to Control Panel
- Go to Hardware and Sound
- Go to Power Options
- Select Change Plan Settings
- Select Change Advanced Settings
- Make sure the 'hard disk' field is set to ‘never’ (Laptop users select 'battery and power adapter').
Otherwise are you having any problems with the system that could be drive related?
What's the current firmware version you're running on the drive?
The MU02 updated on the MX100 had a few changes which could help
•Corrected error handling NCQ Trim Commands
•Improved stability, Efficiency, and Performance during power state transitions

Here is the Lenovo Solution Center screenshot (storage device error) that started this weekend where it clearly shows this error.
I have changed all HDD power plans to Never Sleep as you advised me.
Actually I am running on the MU2 and there is a firmware upgrade to MU3 for my MX100
Should I upgrade to MU3 ?
What to do now with the SSD , should I leave it like that ? And when should I really worry ?
