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 version, I've digged into smart_list.xml and found no matches with the disk and its firmware version. 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've done 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.
