Hello unraid community,

 

I am in a bit of a pickle - I bought a new 18TB Seagate Exos X20 drive to replace my existing 10TB parity drive. The intent was to replace the parity and then start to replace all my data drives all of which are 8TB each.

This is the link to the seagate drive - https://east-digital.myshopify.com/products/st18000nm003d-seagate-exos-18tb-x20-512e-4kn-3-5-enterprise-sata-hard-drive?pr_prod_strat=e5_desc&pr_rec_id=cff53a14d&pr_rec_pid=9373694329105&pr_ref_pid=9116095316241&pr_seq=uniform

 

I tried to add the Seagate drive to the array and unraid recognises the drive fine. However when I try to format the drive, it errors out saying format failed and to check system logs.

The logs seem to be saying there is a read / write error on the drive.

I have already tried swapping different SATA cables and power cables with no wins so far.

 

Also found some info relating to type 2 protection on some seagate drives, and ran the following command on the drive to check:

sg_readcap -l /dev/sdd

Here are the results:

Read Capacity results:
   Protection: prot_en=0, p_type=0, p_i_exponent=0
   Logical block provisioning: lbpme=0, lbprz=0
   Last LBA=35156656127 (0x82f7fffff), Number of logical blocks=35156656128
   Logical block length=512 bytes
   Logical blocks per physical block exponent=0
   Lowest aligned LBA=0
Hence:
   Device size: 18000207937536 bytes, 17166336.0 MiB, 18000.21 GB, 18.00 TB

 

So, it does not look like the drive is protected (but I am a noob on these things so not 100% sure)

 

Worst of all, when trying to test different cables, I broke the SATA port on the existing parity, so am currently without parity :(, so any help would be much appreciated.

 

Both diagnostics and SMART report for the drive are attached.

 

By the way, I ordered 2 x 18TB drives and both have same issues, so am assuming the chances of a DOA are low.

 

Thanks.

That looks like a bad drive, it's not even giving a complete SMART report, but try another cable and SATA port just to be certain.

Have retunred the HDDs as DOA. Thanks for your help.
