I have recently purchased 2 identical HDDs:
- Model Family: Seagate BarraCuda 3.5
- Device Model: ST4000DM004-2U9104 (labeled as ST4000DMZ04)
- Capacity: 4.00 TB [3.64 TiB, 4000787030016 bytes]
I've decided to test them a bit before using them in order to determine if there are any issues. What I did/intend to do:
- SMART Conveyance test
- SMART Short test
- Run "format /fs:NTFS /p:2"
- SMART Extended test
The issue I ran into is that the 3rd point is taking way longer on one of the drives. I ran the command for both of them roughly at the same time (~8PM). I checked the progress before going to bed (~11:30PM) - one was at 43%, and the other one - 14%. I left it overnight, and after ~12 hours, the 1st one had completed (not sure how long it took exactly), but the 2nd one was still at 53%.
I terminated the process and started it again in the hopes of getting a different result, but in about 1 hour it's only 5% done, so it looks like it's not going to be faster.
What could be the reason for this? Should I be worried and just return the drive?
UPDATE: Based on user1686's comment, I've decided to return both disks and buy CMR/PMR disks instead of SMR.

chkdsk-ed /fsck-ed em? It is theoretically possible one got damaged during shipping.chkdsk(orfsck; on Windows 10, but could use WSL if needed). I was under the impression that formatting and using the extended SMART test would be sufficient. @KamilMaciorowski the drives are both connected to the same motherboard, using the same type of cables, and both are connected to the same power supply. What I'm considering is switching their cables and checking again.
