RN104 not recognizing Seagate Exos 7E8 8TB

Thanks

Sebastian

The EXOS is the enterprise line, this particular drive is the basic 7200rpm 2.5M MTBF 5yr warranty variety without any of the other features like full encryption or fips or anything like that.  

I have a lot of WD as well as HGST drives as well.  I usually pick up drives that are deeply discounted through authorized distributors (usually open-box returns).  They come with a full warranty, but sometimes may have been returned for an intermittent problem that didn't show up when the returns processing checked it before listing it.  In these cases, it's just a simple warranty issue--which by the way, a warranteed drive gets the remainder of the original warranty so you don't lose anything.  And in fact, if a drive is about to go out of warranty, the replacement drive will have either the remainer of the existing warranty or 90 days, whichever is more.

Sometimes these drives also get banged around a bit from improper packaging since they usually do not have the original packaging.  I don't think that was the case for this drive and didn't know if there was an issue with these drives and the ReadyNas as I know certain nas units are picky (ahem...synology...ahem...).

I ran tests on the drive with a computer and seatools after removing it from the ReadyNas and it failed some tests, so I'm sending it back for replacment.  I plan to try the replacment in the ReadyNas and expect it to work well this time as the previous drive would work intermittently.

Hi sorry to reopen the case,

I got brand new EXOS 7E8 8TB , but this time I have not inserted it to NAS but connected to PC and run :

crystal - OK

seatools all ok apart from SCT Write Same Erase test , it fails after approx a minute. Do you reckon it is something wrong with Seatools or I am super unlucky and got second bad drive in a row? What do you think?

Personally I wouldn't have run this, as I don't actually want Seatools to try to "fix" a new drive (or really any drive).

How is the drive connected to the PC? Are you using SATA, or a USB adapter?

Since it passed the full overwrite erase and the long read test, I am thinking it might be an issue with the setup, and not the drive.

But I am a bit worried, as the first "same erase" test ran nearly an hour, unlike the second one, which ran less than a minute. You could contact Seagate as they must have seen this before.  Maybe in the meantime, run another short test and another full erase overwrite, and confirm that they still pass.

As a reminder, you don't want to RMA the drive to seagate - if it does turn out to be bad, you do want to exchange it instead.

Thanks

Drive is connected to SATA on the mother board.

Yes I run "fix" as I thought that some bad sectors need fixing for SCT test.

Will create case for segate and let you know the outcome., Short generic has passed, long Overwrite Erase is going on.

Thanks

Sounds like you got a second bad drive that sounds like it's mine, lol.  (Can't be though since Seagate hasn't gotten mine yet. :))

I would simply exchange it again if you're running it straight sata in a computer and are running into these issues, even if intermittent.

Case confirmed by CCL:  SECOND FAULTY EXOS drive in a row! I will get full refund. It looks at least for this line of drives quality control of Segate is poor. I will not be going for exos anymore, thanks for help.

Hey, it's not just you!  My replacement 8tb sounded like it was crunching when I first powered it up in a drive dock to see if it would spin up.  This wouldn't happen if they wouldn't just use the same box as it comes in off the pallet.  A pallet of drives like this will survive bumps, but shipping individual units that will be thrown--no way!

While I was waiting for my 8TB, I found a deal on a 12TB exos.  Works like a charm on 4.2.28 showing 0% of 10TB used on the front page, and showing 11176GB in health status as well as "11,885,420,335,104 bytes free". :)  Can't wait to get my other drive back and pair it with this one and see what happens. :D
