Check health of SSD in Raspberry Pi
 
I have Raspberry Pi nano with USB SSD drive connected.
Ubuntu 16.04.7 LTS.
How to check health od SSD drive?
smartmon already installed.

Code:
root@NanoPi-NEO:/home/pi/Pobrane# smartctl -a -d sat /dev/sda
smartctl 6.5 2016-01-24 r4214 [armv7l-linux-4.14.0] (local build)

Any idea? Another tool?

mackowiakp,

Did you run the Long test?

Code:
sudo smartctl -t long /dev/sda
The following indicators should ideally be zero:

#5 Reallocated_Sector_Ct (yours is 18)

#197 Current_Pending_Sector

#200 Multi_Zone_Error_Rate

mackowiakp 02-17-2024 03:19 AM
OK. what is max numer of Reallocated_Sector_Ct ?

mackowiakp,

There is no "max number" for Reallocated_Sector_Ct.

You need to make sure that all your personal data on that drive is backed up elsewhere and then keep an eye on the Reallocated_Sector_Ct figure by SMART testing (Long test) periodically.

Your SSD will probably be okay for a while, but it is going to fail, so budget for a replacement SSD.
