Seagate Exos 7E8 missing from the database (ST8000NM000A, ...)

[niconiconi]

Hello. I purchased some Seagate Exos 7E8 hard drives, and I found this series is not in the database yet. I made a simple patch to include all models in the ​Seagate datasheet.

As commented, I tested it with my ST8000NM000A-2KE101/SN02 and ST6000NM021A-2R7101/SN02. After applying the patch, attribute 240 "Head Flying Hours" started to increment seconds by seconds, so it's probably correct. Also, I found "Power On Hours" looks like an hour-only integer value, even with "-v 9,msec24hour32", it's only reported at hour-precision, we probably don't need it, thus I didn't run the short SMART test.

However, there's still an unknown attribute 18. I'm not sure if "Head Health" is the appropriate option, so I didn't add it.

The full output of "smartctl -q noserial -x" for the two hard drives are attached, please double-check my patch, and see if whether attribute 18 "Head Health" is needed, thanks.

Thanks for this patch. Experience shows that regular expressions for Seagate drives should not be too coarse to avoid false detection of other series.

SAS should be excluded, see the FAQ.

Possibly better: ST[123468]000NM0(0[01234689]|1[0236]|2[1256])A-.*.

Thanks for the feedback. I've removed all the SAS drives from the list and improved the regex according to your suggestion. I saw only SAS drives have "NM03", thus I also removed the "3" in the first group from the suggested regex.

New patch.
