When using the Transcend SSD Scope Software (windows) it gives us:

 [0x09],  Power-On Hour Count,  17
 [0x0C],  Power Cycle Count,  6
 [0xA9],  Total Bad Block Number Of System,  0
 [],  Later Bad Block Number Of System,  0
 [0xAD],  Minimum Erase Count,  1
 [],  Maximum Erase Count,  2
 [],  Average Erase Count,  1
 [0xAF],  ECC Fail Count,  100
 [0xC0],  Power Loss Count,  3
 [0xC2],  Current Temperature,  25
 [],  Minimum Temperature,  25
 [],  Maximum Temperature,  25

So for this SSD we could simply add:

"-v 169,raw16(raw16),Bad_Block_Count "

For 173 it seems that

"-v 173,raw16(raw16),Erase_count "

would be more appropriate than

"-v 173,raw16,Erase_Count " // JMF661: different?

And for 175

"-v 175,raw48,ECC_Fail_Count "

instead of

"-v 175,raw48,Bad_Cluster_Table_Count "

The question is, if we should make a new entry for all
"TS(32|64|128|256)G(SSD|MSA)[37]40K?" drives or just one
for the TS32GSSD340K or simply add/change the attributes
in the current "JMicron/Maxiotek based SSDs" section?

The answer requires comprehensive research in past submissions. Leaving ticket open as undecided for now.

Please provide a full smartctl -x -a ... output of an affected drive.

[Andre]

Added smartctl outputs of 3 drives...

[Christian Franke]

Thanks.

BTW, you could use the -q noserial option to suppress Serial Number and LU WWN Device Id outputs.

[Andre]

Right, thanks for the reminder. But I already stripped of the last 14 chars so it should be sufficiently anonymous :-).

If you want me to get anything else from these drives please let me know.
