I received 3 of these yesterday. Had a heck of a time with them. All three were showing 512 for the sector size (logical & physical) and zero total capacity. One had an additional odd behavior of timing out and causing "Spinning up disk..." to be logged in dmesg repeatedly.
I used sg_format (linux) to format them with a 4096 sector size, since these are 4kn, and they've been working fine since. I'm currently running my torture test on them but so far so good.
None of my other He8 drives (same part #) behaved this way but they are a bit newer. These three drives are all dated Aug-2015 but my other He8's are 2016 and 2017.
