Question Bought Seagate drives, are they okay?

[AaronVB]

Hi, as the title suggests, i bought 2x 12TB Seagate Barracuda Pro Compute drives from an ebay seller with great ratings. Once i got them i instantly ran a long/"extended offline" SMART test, and they looked fine. I heard about all the fake/broken/... drives lately and got a little scared, so i went back and checked on them again.

I set them up in a btrfs raid 1, the second of the two drives had a huge number of checksum errors but btrfs fixed them all and im not sure if i just set it up wrong or if the drive is failing. Both drives are ST12000DM0007-2GR116 and show up with huge Raw_Read_Error_Rate, Seek_Error_Rate, Hardware_ECC_Recovered, Spindle Motor Power-on Hours and Head Flying Hours values, which are normal according to wikipedia which links to an article explaining the values and a pdf talking about it too. Idk, im really suspicious and would like more opinions on these drives.

Seagate's verify page says

The scanned QR code is a valid code for a drive with 12000 GBCapacity and serial number ending in: -----XXX
If the capacity or serial number does not match, please contact the place of purchase with any questions about the product.

which does match. Entering the serial numbers into the warranty page however, gives me

Please contact the place of purchase.

they were advertised as "factory recertified", so shouldnt seagate offer warranty on these, instead of the seller? Ill attach the SMART and FARM values, please let me know what you all think! I still have a few months to send them back.

these are used drives
refurbished or factory recertified usuallay don´t come with warranty at all, sometimes about 6 months, depending on the seller
does the label say this?
https://horizontechnology.com/wp-co...Drives-Locate-Pull-Out-Horizon-Compressed.jpg
or not?

factory recertified could mean anything. The factory isn´t named as seagate.

if seagate doesn´t know if it´s a warranty case, most likely it´s an OEM drive

Checksum errors at the file system level would bother me , but huge Raw_Read_Error_Rate, Seek_Error_Rate, and Hardware_ECC_Recovered values are normal. They represent sector counts or seek counts rather than errors.

These are the numbers that I can't reconcile:

  9 Power_On_Hours          -O--CK   098   098   000    -    1965
240 Head_Flying_Hours       ------   100   253   000    -    24h+55m+08.314s

0x03  0x008  4      1140202695  N--  Spindle Motor Power-on Hours
0x03  0x010  4      1140202104  N--  Head Flying Hours

        Spindle Power on Hours: 14025104583
        Head Flight Hours: 14025103992

The figure of "24h+55m+08.314s" can be better understood when the raw value is viewed in hexadecimal mode. The lower 16 bits (or 32 bits) is the POH value in integral hours. The uppermost bits represent a partial hour in milliseconds.

I also see ...

Current Relative Humidity: 175

... which is a strange number, and even more so for a helium drive.

Edit:

Seagate's FARM spec states that the Current Relative Humidity is reported "in units of .1%". So that's 17.5%.

yes, the label does say:

Seagate
12TB
Recertified Product
BarraCuda Pro

factory recertified usuallay don´t come with warranty at all

that does make sense then; i could swear the seller advertised 2 years, but when i go back to the ebay listing it says 1 year - maybe they edited the listing and ebay is showing me the new one? i gotta check if i have any screenshots, im sure i do.

i pulled the btrfs device stats like this:

# btrfs device usage /mnt/Raid
/dev/sdd1, ID: 1
   Device size:            10.91TiB
   Device slack:              0.00B
   Data,RAID1:             88.00GiB
   Metadata,RAID1:          2.00GiB
   System,RAID1:           32.00MiB
   Unallocated:            10.83TiB

/dev/sde1, ID: 2
   Device size:            10.91TiB
   Device slack:              0.00B
   Data,RAID1:             88.00GiB
   Metadata,RAID1:          2.00GiB
   System,RAID1:           32.00MiB
   Unallocated:            10.83TiB

# btrfs device stats /mnt/Raid
[/dev/sdd1].write_io_errs    0
[/dev/sdd1].read_io_errs     0
[/dev/sdd1].flush_io_errs    0
[/dev/sdd1].corruption_errs  0
[/dev/sdd1].generation_errs  0
[/dev/sde1].write_io_errs    7280396

[/dev/sde1].flush_io_errs    65
[/dev/sde1].corruption_errs  0
[/dev/sde1].generation_errs  0

and that doesnt look good imo. seems like btrfs is set up correctly, it knows the raid has the two drives and is writing to both of them, so i doubt its a user error at this point. the two drives both have the same uuid as output by blkid, so i doubt its an error in my fstab either. im leaning towards sending them back and saving a bit more for new drives...
