I got some vendor “rebranded” hard disks (from HP), I guess they are original Seagate given some reference on the sticker “ST4000NM0035” (but otherwise, the rest seems to be HP rebranded). And on the Seagate warranty check, the serial number returns the right model number but doesn’t display the warranty (I’m not worried about the warranty, it’s long passed ).
For such drive, do they also change the firmware?
I’m asking because I get strange SMART results:

The SMART attribute list is very short…
The SMART error log and self-test log are not supported!
And it says that the disk is not in the smartctl database.
I guess this is due to the firmware, hence my question.
And, any guess as why they would do such thing (especially the log)?
The SMART test (at least short) can be run but there is no way to see the results.
This is a bit frustrating…
For now I’m not planning to use these disks (or maybe for backup).
All looks good and apparently it does support SMART self-tests.
I have to assume the “strange” readings you were referring to were the three crazy values, Error Rates. This is normal for Seagate and does not reflect the true error rate at fact value. Subtract hex FFFFFFFF from that value and the remainder, if any, is the true value. Seagate uses this register for more that one purpose and anything over that value indicates a failure.
The only odd thing I saw was the Maximum temperature of “-40” and that is odd, and must be an incorrect value.
Run a SMART short test daily and a Long test once a week, or just keep doing what you are doing, it still works.
Well actually I ignored those!
I mean I know that Seagate has a different interpretation of it but I didn’t look into it yet so thanks for the details!
The “strange” readings I was referring to were the absence of logs with -a parameter (which was resolved with the -x) and the rather short list of SMART attributes.
Just for the story, the first time I checked these drives, they were connected on an integrated controller set to HBA mode. And I thought this was because of the controller that wasn’t really acting as an HBA… But then I tried with other drives and it worked well and now I confirmed that it is indeed the drives since I’ve tried them on an other system, directly on the motherboard’s controller.
I am learning to never be surprised when it comes to the incorporation or lack of good incorporation of SMART in a drive. It is odd but at least the drive is working, and working well.
That is also why I came here to ask the question to get more insight from more experienced members! It’s always good to have other perspectives.
And thank you very much.
