I currently have the following 2 drives

V9M9K

Seagate ST4000NM0025

3.5in 4TB 7.2K 12Gbps SAS Hard Drive

firmware: DE07

One drive shows up with driveLine Attribute in CLI with EnterprisePlus

One drive shows up with driveLine Attribute in CLI with EnterpriseValue

drives were inserted into SC200 that was hooked up to SC8000 ( SCOS 6.5.3 ) controller

also tried hooking the SC200 to SCV4020 ( SCOS 7.1.4 )

so far the only difference we can tell between the drives is DOM - date of manufacturing. it seems we have found that all these drives with a DOM of Jan 7 2017 and older will come up with EnterpriseValue and any drive newer such as Nov 7 2017 comes up as EnterprisePlus. I was able to confirm this by testing about ~80 drives with DOM's Jan 7 2017 and older, but I have only been able to test about 3 drives with DOM of Nov 2017. I also found 2 drives with DOM of Jun 2018 that come up as EnterprisePlus but their firmware is DE05, which is older then DE07. 

more information can be provided if needed but is this a manufacturing error? is there some CBD on the drive that is messing this DriveLine value up? The drives are used and from unknown origin, but i still dont understand how they can have everything the same and still have different DriveLine attributes.
