Proper attributes for SanDisk SDSSDA(120|240|480)G

[Artem S. Tashkinov]

No idea how to create a proper patch, so:

"-v 5,raw48,Reassigned_Block_Count "
"-v 166,raw48,Min_PE_Cycles "
"-v 167,raw48,Max_Bad_Blocks_Per_Die "
"-v 168,raw48,Max_PE_Cycles "
"-v 169,raw48,Total_Bad_Blocks "
"-v 170,raw48,Grown_Bad_Blocks "
"-v 173,raw48,Average_PE_Cycles "
"-v 230,raw48,Media_Wearout_Indicator "
"-v 233,raw48,NAND_GiB_Written "

smartmontools patch for SanDisk? SDSSDA(120|240|480)G - OK to merge

[Christian Franke]

Thanks for this patch.

Please provide a sample smartctl -x output for this device.

Please add //"-v N,... " comments for the attributes of this device which are handled by the DEFAULT settings. See other SSD entries for examples.

Here is a quote from the smart_list.xml file from some 2018 version of the SanDisk tool (see tickets #464 and #799):

<!-- SanDisk SDSSDA* is being used by multiple hardware, so we define those drive by fw version -->

This comment is followed by 16 firmware patterns. Please check which one matches this device and add a firmware regex to the entry.

Hello!

I have just faced with the same disk in our server. I've adopted the patch for the drivedb.h version
7.2/5224 2021-06-06 15:55:46. I also attached smartctl -x output before and after applying the patch. Speaking about filtering by firmware, I've digged into smart_list.xml and found no matches with the disk and its firmare. The first suggestion was

  <ref fname="aphrodite_generic.xml" matchType="prefix" length="8" fwprefix="U2" version="1.1" />

but contents of the aphrodite_generic.xml surely describes another drive model. Even amount of metrics differs.

So I gave up using smart_list.xml and looked for a file with exactly 20 metrics. Happily there is only one and it's plus_generic.xml. From the name of the file I'm doing a suggestion that there is no need in firmware filtering and it should be general block for SanDisk SSD Plus like it's done in Artem's and my patch.

This was filed two years ago (!) along with the patch.

What's the holdout exactly?
