so in all i bought 24x of these, 8x then 8x then 8x (over about 6 weeks). All are awesome (all are 0-1% used writeE , 0 sas errors).
however 2x (of the last batch i got) i noticed were acting weird. I was trying to run some benchmarks on an extra adaptec 71685 card i have (just to see that cards speeds), but 2x of the 16x i had attached were showing up (in maxview on windows) with a yellow ! and were unusable (maxview info on the drives show unknown sector size).
(jump to bottom for the answer/fix)
Window also would not see the drives at all. so i moved those 2x, along with some others over to a ubuntu 18 live usb boot machine (with a LSI HBA) , and all showed up in the gui disks app, but the same 2x showed up as un-usuable (or something simlar, also fdisk would not list them).
smartCTL -a showed their data but showed sector size as 520b. same with sg_info (or sginfo).
so it was clear i needed to chnage the sector size to 512b. ubuntu 18 live, comes preinstalled with the latest sg3-utils pkg (a tool set for dealing with SCSI or SAS devices).
in google searches (which led me to some posts here on STH ofcourse!) ppl were using this command to change HDDs and SSDs to 512b (often from 520b):
sg_format -v --format --size=512 /dev/daXX (or /dev/sdXX)
or if that gave errors then:
sg_format -v --format --size=512 --six -v /dev/daXX (or /dev/sdXX)
however ubuntu 18 live kept giving me some error on sg_format like:
sg_format: symbol lookup error: sg_format: undefined symbol: sg_memalign
(however this is an issue specific to ubuntu 18 live, or the latest sg3-utils, as even when i tried the 1st command on full accessable 512b disks, it gave that same error.. fyi i was using /dev/sg5 ect on ubuntu18).
i then figured let me try them on my FreeNas 11.2 machine (also w LSI HBA), as i know FN is good with weird disks and has a full suite of utils, stock. first i just tried using the FN gui to wipe the disk, but it ofcouse gave me this error (related to 520b sector and not being 512b):
Disk wipe job failed: Command '('gpart', 'create', '-s', 'gpt', '/dev/da18')' returned non-zero exit status 1.]
or
Disk wipe job failed: Command '('dd', 'if=/dev/zero', 'of=/dev/da18', 'bs=1m', 'count=32')' returned non-zero exit status
FN reported the same 520b with smartctl -a and sginfo,
but in FN this command did work! (and now the 2x disks are full accessible/working on all platforms!)
sg_format -v --format --size=512 --six -v /dev/daXX
(note this command on FN failed: sg_format -v --format --size=512 /dev/daXX )
I was going to try ubuntu 16 live, b4 trying on my FN box (which i think would have worked too btw).
FWIW, one of these 2x 520b disks from this seller did have 3% WE used up, the other had 0%
SGformat command working, and then below that:
