Still holding up after 2+ years

Works as they should, yes these have an older production date, but they came vacuum sealed and in new condition. No adnormal noises and the synology disk utility says they are healthy.

Works great I upgraded a hard drive no issues

i was kind of worried really did not see this was a renew into after i ordered i had 4 pages loaded and ordered the wrong one. but so far i do not regret it.. no noise. the drive is reading at 3.6tb not 4tbthe drive does not pick up in the window. but does pick up in the device manager. so for the ones that have no ideal how to fix that. just hold windows key and hit X go to drive manager. click on the drive and it well give you a option for that drive. click ok. then give it a drive letter and format it. really simple fix. all in all the drive seems to be working ok. i got this drive cause i fast formatted another drive by mistake and i am using a program to restore files and needed another drive to save what i can. i love this dudes packing like he/she packed this batter then a store package lol. also drive was clean like new.

Background: I've had this same model from 2016 (bought new) and it was working really well, so I got another one since it was cheaper than other options, and I didn't need the fast write speeds.I plugged in this hard drive using an external hard drive adapter and initialized it as GPT (MBR only detects up to 2TB) and disk management only saw 1.6TB. Knowing this issue (since I had one of these), I installed Seagate's Extended Capacity Manager which essentially unlocks the remaining part of the disk. After installed all the needed drivers, I get a message that says "This drive already has the extended capacity", which it definitely doesn't as I'm still seeing 1.6TB. I restart my computer, I plug it into the onboard SATA port this time around, and still no dice. I download other hard drive partitioning programs to see if I can remediate this issue, but to no avail. Thankfully, this is an Amazon renewed product, so I can return it with peace of mind, so I got a replacement product, only to find out that the replacement acts the exact same way.Please note that these hard drives are fairly old, the two I received were manufactured on 05/2014 and has had all their SMART status wiped, so I don't know where it has been.TL;DR - 4TB only shows up as 1.6TB, seagate drivers don't work. Got a replacement, same problem.
