Guess I was lucky, we ran a lot of these over the decades when things were far more unreliable than now and never experienced anything like that. Manufacturing issues, sure, but we always had everything we bought run on stress for 48 hours and see if that killed it, if it didn't, it didn't usually break anymore (I have many of the machines from mid to end 2000s still and they don't have diskfailures now while they ran for many years).

The older hdds imo are more reliable than the newer ones. They're pushing for density, and mitigating the inheritly higher sensitivity through aggressive error correction.

Would like to know the manufacturer and model.

Sorry, this was back in 2006-2007 time frame. I have no idea on model numbers as that's just not information I ever cared to commit to memory.

My time frame is about since end 90s to now. I saw more failures in general in the olden days. I have quite a lot of rented servers at traditional hosters or Colo that have not been down outside kernel security updates for 10+ years. No hardware issues. I am now swapping them out for new servers which cost less for more, but hardware wise they have been pounder hard for 10 years without issues. All hotswap raid5 drives, so when broken, they or us just fixed it without downtime.
HA! I had received new 16-bay chasis and all of the drives needed plus cold spares for each chasis. Set them up and started the RAID-5 init on a Friday. Left them running in the rack over the weekend. Returned on Monday to find multiple drives in each chasis had failed. Even with dedicated one of the 16 drives as a hot swap, the volumes would all have failed in an unrecoverable manner.
All drives were purchased at the same time, and happened to all come from a single batch from the manufacture. The manufacture confirmed this via serial numbers, and admitted they had an issue during production. All drives were replaced and at a larger volume size.
TL;DR: Drives will fail, and manufacturing issues happend. Don't buy all of your drives in an array from the same batch! It will happen. To say it won't is just pure inexeperience.
